EP's Rock Force

[EeePee]

Truck whore that I am, I had to get one of these too. Will it take my seriously abused Berg's place as my comp truck? That is the question at hand my friends. We shall see. If not, then I still have a cool Kyosho truck to add to the collection.

As much as I want it to work perfectly right from the box, I just don't see that happening. I'll be adding the high speed gears and dig option parts when I get them, along with Eritex's wheels. That will be my real starting point.

Being on board with Reign RC, that will be my choice for an aftermarket chassis, when that time comes.

It sits here in running form, with the electronics slapped in place so I could try it out already. I don't think they can stay there if I mount the body. I believe it sits quite low, and the electronics will hit. Speaking of the body, it's damn cool, but not legal so I'm not sure what to run at the comps...

For the moment, I have a Holmes Hobbies 10 turn Cobalt Puller and MaxAmps 3S 2200 lipo pack.

http://img301.imageshack.us/img301/7236/img0452vb9.jpg

I did make a change to the gearing after the first run. I went from an 18 tooth pinion to a 26. Stock final drive is ~143:1 and now I'm at ~99:1. It's not terrible, but I'd like just a bit more. It has a lot of get up and go snap to it, but I want just a little more. Enough so it's like a lunge forward when you gun it.

http://img139.imageshack.us/img139/6971/img0449et0.jpg

Still a lot of room for a larger pinion gear, notice how the screws are placed.

I have very lightweight oil in the shocks. 15 in front, and 20 in back because they are laid down a little. I didn't modify the shock pistons like they suggest, and with 40 weight in the cold, they wouldn't move at all. I've cinched down the suspension as Kyosho has it spec'd out in the instructions. Skidplate is pretty low this way. Also, I've started cutting out a longer axle mount for the Panhard bar. After speaking with a suspension geek friend of mine, and wanting a higher skidplate height, and parallel Panhard bar, I can move the Roll Center up, and idealy have less weight transfer. Lowering the chassis side of the Panhard will lower the Roll Center and increase weight transfer.


So this here is the beginning of my Kyosho Rock Force experience.

So why is the body not iegal,

nice motor you should have alot wheel speed with it "thumbsup"

Let us know how it drives ;-)

[roborg5000]

Do i feel a win coming next week ? :ror:

[killjoyken]

The body's only 4" wide. Rules require a 5" width.

He's got no wheel speed with that 99:1 ratio. :lol: Not to worry, high speed gears are finally here.

EP: Can't wait to see what you do with it!

[EeePee]

Aaron, John beat me to the answer, but he is correct. It's unfortunate.

Do i feel a win coming next week ? :ror:

We'll see! Besides my Berg is always ready to kick ass if I'm not ready to wheel the Kyosho yet. One thing is for sure, the Kyosho can go so incredibly slow, it makes me want to relearn the super slow approach to crawling.

[EeePee]

Okay, well John deleted his post, but killjoyken has an answer too.

It's got some get up and go, nothing ridiculous though. Not like the new trend of rock racers out there.

[Unimoger]

sure ,:lol: I 'll play along. what's next?:roll: we want video.8)

[Georgerm]

crap you got another new toy to beat us all with.

[EeePee]

sure ,:lol: I 'll play along. what's next?:roll: we want video.8)

What up Ben!? Next... hmm. Well, I'll probably put some foams in the tires, and glue them to see how they do. I've read not good, but I gotta try for myself. What I'll probably do is mount up my VP DH Comps with the Panthers already on them. One less thing to fault, as I know those work great. Until Eritex Gerame gets us those RF wheels he's shown off.

Video... I haven't made one of those in a long time. This could be the right time to.

crap you got another new toy to beat us all with.

Yeah being a single 30 something with an okay paying job has some perks, like being able to buy toys when I want. I can't complain.

To mount the DH's you'll have to bolt the hub adapter first, then bolt the hub adater to the wheel. Unless you have a 10mm socket that can fit in the DH. You'll also want to use the narrowest offset hub adapters too.

Thanks. I think I read that in your thread, or some post you made.

I hope the red Loctite I used on those wheels isn't a pain in the butt. :roll:

I thought you only ran Droopers?

That's his pants your thinking of.



Looks good Cory."thumbsup" Have you had it on the rocks yet?

[4stAir]

so you bought one of those screaming crawlers too...:lol:

i am gonna wait till i see you or john make one work on the rocks then i will go get one to."thumbsup"

[EeePee]

I thought you only ran Droopers?

Nah, for two days back in 2005 with my TXT, and just this Berg thing I have. All my other trucks have been sprung. I like the spring, but the droopy Berg does good. Probably cause it doesn't have those damn driveshafts.

That's his pants your thinking of.

Looks good Cory."thumbsup" Have you had it on the rocks yet?

:shock: At least you said pants! And thanks Josh.

I've not had it on any rock yet, but I've driven it a little bit. Tuesday will be it's first scratch. I can't wait. :twisted:

so you bought one of those screaming crawlers too...

i am gonna wait till i see you or john make one work

This thing IS TOTALLY a screamer, but in a good way. I have every intention in my world to make it work good, and at first with as minimal effort as I can. I don't think it's nearly as bad as some of the nay sayers do, but of course, I haven't put the thing on a single rock yet.

Got an old Proline Courier body on it for tomorrow's first outing. Looks okay I guess, but it's no comp body.

Good Luck Cory...

I haven't touched mine yet. Figured I will wait for some packages to arrive and do it all at once... ;-)

Let me know if the 10T heats up. The 7T was generating some heat at Cole's Place...

[saydee1800]

so are you guys saying that these Rock Force are crap. I have been really wanting to get one. They look great. Very Solid.

Thanks John. Yeah the 10T heats up. It doesn't have that smell of hot, but it's warm for sure. But so are the worm gears, ESC and battery. I can feel the axle case is warm after a while, that's kind of weird.

so are you guys saying that these Rock Force are crap.

I'm not. I think it's pretty freaking sweet. If you're not sure if you want to spend the dough on one, then give it, and me, a little while and I'll give you the scoop on it. I've driven almost pretty much everything and if it doesn't work, I'll tell you why.

You best believe I'm getting one of those. Probably get the Venom crawler too. One with the most toys at the end wins right? "thumbsup"

I'm not even going to give the stock tires a chance. I know the Panthers work great, so there's one less variable in question.

[EeePee]

Hey EP how'd it go?

Well lemme tell ya how it went.

Firstly, this is likely the best out of the box crawler we've ever seen thus far. I set it up pretty much as the directions have you. I have the zip tie cinch downs set so I have 2 1/2" under the skid. That's kind of low in general, and a 1/2" too low for where I typically crawl. And it's also a little wider than what I run, which all leads up to one thing. Stability. This truck is stable! Off cambered, off kilter, teetering on three, or two wheels, stable. But nonetheless, it's too low. So that means the aluminum skidplate was scraping everything, and we all know how aluminum is on the rocks. Too soft, and too sticky. And the worst part is the leading edge corners, right near the ball ends for the links. Gotta do some heavy throttle control blips and steering wiggles to get it unstuck, or take a reverse. I didn't have much of an issue with the axles getting stuck on anything. Well, once in the back on a corner, but that's driver error, and what axle wouldn't get stuck like that?

The suspension is very smooth. I have only 15 weight in the front shocks, and 20 weight in the back shocks. But with the piston being the way it is, the rebound and compression dampening is still pretty slow. And with the front shocks being vertically mounted, they'll have a more direct effect than a set of laid down shocks will.

Torque twist? A little, maybe? If so, it was never bad, not ever out of control flop to a side and stay there. Really, it was hardly anything at all. But what helps with that? Each front tire/wheel combo weighing 1 full pound.

Which leads me to climbing our rock wall. My buddy measured it at 63 or 64 degrees and it went up it. Had to drive it carefully as I might be about at the limit set up as is, but it went up. Rear tires wrinkled a little, the truck took a set, and slowly it crept up with all four tires on the ground. Flooring it while climbing made the truck hop right up and off the face of the climb, and settle back down ready to climb more. Which is great, cause that's just like my Berg and Axial. Much better than flooring it and the thing flips over backwards. That's unacceptable to me, as if one truck of mine can do that, then all of them should be able to, or it's inferior and can go sit in the corner with my Hi Lift.

So, I'm driving this thing for a little while now and thinking to myself, this thing is actually pretty sweet. It's not my Berg comp truck by any means, but it's not that bad at all! Then I had a small problem...

[Georgerm]

this is getting good what happend!!!!!!!!!!!!!!!?

[THnCS]

Then I had a small problem...

And Then:?::ror:

[XJ Farmer]

Nice info, I'm impressed"thumbsup" Can't wait to hear more.


Later
Farmer

[EeePee]

Word up guys, I really like evaluating trucks. I'm a nit picker.

And Then...

Thermal'd the Tekin FXR! Holmes 10 turn Cobalt and a MaxAmps 3S 2200 with a CC BEC and 99:1 final drive thermal'd! A little while before this happened I thought I could smell the odd stink of a hot motor. Was I surprised? Yeah, a little, but first a short story about someone's Kyosho from the week prior.

Someone I know got a Kyosho before me and was ever so kind to drive a while to bring it to our Tuesday Night Fights that I attend regularly. He had a stock Slash motor in his, which is a 12 turn 550 can and it was powered by a big 2S lipo battery. It's comparable to a 19 turn 540 I believe. I was driving the truck before the competition started to just check it out, and noticed how the whole truck was warm. No big deal? He insisted I drive it for the comp, so I did. Well, before the second gate was cleared the truck stopped and the metal tab motor brush spring was taco'd in half, rendering it useless. All I could do was apologize to him for his drive out and killing the thing. I still don't understand why it happened, maybe the motor is more of a turd than I thought.

So I knew the truck would get warm by just by running it. What I didn't know was how HOT this thing got when you REALLY run it! Do NOT touch the motor or you're gonna scream. The skidplate was radiating heat, and more surprising was how warm the axle cases were! Heat from the worm gears! Weird!

So I thermal'd a crawler, and during all my testing with Tekin, I've never done that. Maybe I should drive it a little more slowly? But to drive it medium speed, I gotta be deep into the throttle. 99:1 final is still slow really. But the torque. You can feel the torque! And POWER.

Funny thing about so much power and torque. Those plastic spur gears, man, they don't like it when you try a little too hard. I chewed up two teeth a little bit. I moved my motor over and practically buried the pinion gear teeth into the spur. Sounds bad, but worked for the rest of the night. Which by the way, took a few battery charges. We all know how long a 2200 mah pack should last, but this combo went through them like something maybe half the size, I swear.

So if I'm recalling correctly, other than a few steering knuckle screws coming loose, that was it for any real issues. Oh, the truck is a little short at just about a 1/16th over 12 inches. And that's at a low ride height, so it'll shrink a little if you raise it a bit. Back to the good stuff...

[dkingston]

Nice write-up!

How would you compare how the Rock Force worked either as well, better or worse than others?


- David

[Rc_Cam]

traxas did have a little problem with those 12 turn motors throwing brushes so i wouldn't blame the crawler for that one.

thanks for the info about how the rock force runs. i'm still a low wheel speed crawler so i am hoping that the gearing won't be a problem for me.

[EeePee]

How would you compare how the Rock Force worked either as well, better or worse than others?

To compare it to what I was running before would be tough, as it was either a decked out Berg, or a tweaked and tuned Axial. I can try to though.

traxas did have a little problem with those 12 turn motors throwing brushes so i wouldn't blame the crawler for that one.

Oh, okay. I've killed two of them things in my Slash, but I thought they'd be fine in a cralwer, guess not!

I have more to share, I'll have to get back to it later, as it's little late for me.

[JOOTZ]

good hands on review, so the esc and motor combo for this rig is still up in the air ?

[Georgerm]

you bringing this thing to saturday right EP

[Rckcrwlr]

We all know how long a 2200 mah pack should last, but this combo went through them like something maybe half the size, I swear.

I realized this two. Hoping that the HS gears with the right Spur/pinion combo will help.

I will be running mine in a comp this year with the changes...we'll see what happens.

[EeePee]

Thanks, yeah, I'd say it's still up in the air. But with the HS gears trickling in, we'll get it all figured out pretty soon. Or not...

you bringing this thing to saturday right EP

Yeah, but I'll probably run the Berg.

I realized this two. Hoping that the HS gears with the right Spur/pinion combo will help.

If it's because there's no load on the motor, we'll just have to gear it like other trucks I guess? The 15:1 cuts the reduction in half right there, so those will most likely help. But then the new concern is the increased speeds and friction and the heat it causes in the axle. Could be interesting. Could be nothing at all. Can't wait to find out.

I'll take smoking hot axles over smoking hot electronics any day though.

[THnCS]

I know when Jason brought his RF out at our fall finals, it only lasted about 10 minutes. He had a 19t motor in his and it went up in smoke also. The esc was warm, but still worked. The extra load on the motor is the main concern I have with the worm drive axles. Never thought to check if the axles had any heat coming from them. Hopefully the high speed gears will allow the use of a 35-45t motors and still get the wheel speed we all know and love. Also improve the life of motors.

[blueridge72]

If it's because there's no load on the motor, we'll just have to gear it like other trucks I guess?

It's not looking good. Killjoyken overheated a Holmes 35T at a 53:1 ratio. Sounds like those worm drives are very inefficient at the speed we want them to run. Should have known. There's a warning in the manual about the gears getting hot. All that heat comes at the expense of the motor and ultimately the battery. Crap. :sad:

[Rckcrwlr]

Just remember that this is unexplored territory with the worm gears...it is going to take some time, motors, escs and batteries until we find the right combo.

You also have to enter this territory with a new or open mindset. What works for R/P may not work for Worms...

That is why there are several guys building theirs and testing different set ups.

[JOOTZ]

has anybody tried the manufacturers recomended motors and still have problems with heat or electronics getting nuked still ?
im thinking kyosho for sure would have put a lot of field testing behind their recomemdations for this rig.

[dkingston]

The rig EeePee mentioned with the slash motor was mine. I had run it quite a bit and in fact run a couple battery packs through it on those rocks before that failure. Keep in mind, that motor failure was a common one with those motors. I have seen them fail that way while racing with stock traxxas electronics.

That setup, (essentially a 19T 540 with 25T pinion and stock gearing) worked well minus the wheel speed that most would want. My Mamba Max and battery did not get too warm at all.

I installed the HS gearset. My anticipation is that the final motor/pinion combo, to get folks where they are used to being wheelspeed wise, will be a fairly similar setup to what you run now. There will be extensive testing this weekend. Possibly a 45T if you used to run a 55T? The findings will be reported here!

I was crawling with Ken when the overheat occurred. He and I have talked about gearing a few times now trying to figure out what exactly happened.

What I do not know is if there is any load difference in a 53:1 ratio if the reduction is done more at the transmission and then less at the axles or like it was 2:1 at the trans and the rest in the axles.

If it does the same thing with the high speed gears.....

thanks for that info, i am very tempted to get my hands on the RF as more become available on the market, however all the testing done on it now with regards to motors and the addition of ESC makes me sit back and take a look at what options are coming out, for sure this will all be addressed in this forum.

Jootz,

There are more in the country right now, they will start showing up soon. In fact, I believe Stormer still has some if I am not mistaken.

Hasn't rbgerrish been running worm gears for a little over a year on some custom axles? His rig seemed to have plenty of wheel speed. Here is a link to his thread....axles are 50:1
http://www.rccrawler.com/forum/showthread.php?t=124209

That brings me to the next point. What about possible running a motor right to the pinion? I know that is an option on the axles rbgerrish is using offers.

Just some thoughts.

[killjoyken]

But he said he lost wheelspeed. ;-) He's also running MOA.

Yeah, I lost wheelspeed, but I gained slow speed control, which is something my old truck didnt have...

[e-hills4x4]

he lost wheelspeed because he went from 30:1 to 50:1. the truck is still plenty fast. it was a rocket before

[killjoyken]

he lost wheelspeed because he went from 30:1 to 50:1. the truck is still plenty fast. it was a rocket before

I see. But again, it's MOA. And the motors (as far as I can tell from the pics) are coupled directly to the worm gear. We're dealing with a completely different setup. 1 motor trying to turn 2 axles doubles the load on the motor. I'm going to try a Holmes 30T with a 72/21 tomorrow before my high speed gears show up next week.

It's still going to take a lot of tests to find that sweet spot, but regardless everyone will have a different idea of fast. :)

[EeePee]

Got the HS gears and dig on the way.

Yay.

[JOOTZ]

Got the HS gears and dig on the way.

Yay.

really interested how you gonna set this up, i will try to get my hands on a rockforce this new year and follow your build, if you dont mind.

[EeePee]

I'm pretty interested in what I'm gonna do too! The HS gears I think, are mandatory. I believe it would be in Kyosho's best interest to either include them, or swap out the low speed gears. Not that the truck is unusable, not by any means, but with the certain style of driving we have developed, it's just not suited for that. And I tried to make it work, but thermalling controllers is not an option, and the truck as I set it up, is still too slow.

So, once the HS gears and the dig come in, it's game on!

Oh, and of course I don't mind. I wouldn't post as many truck builds as I have over the years if I did. "thumbsup"

[Dewmerz]

I would agree on the high speed gears after seeing the RF run. I like running small low mah batteries to keep the weight down. With the stock gears a faster motor is needed to reach the same speed my Axial runs requiring a bigger battery or same size with a higher C rating sacrificing run time.

As mentioned in another thread the HS gears don't come with the shaft for the main gear. The shaft only comes with the stock low speed gear set. If Kyosho included the HS gears in the RF the HS gears would have to include the shaft so people who damage it don't have to buy a useless (to them) low speed gear set.

[EeePee]

As mentioned in another thread the HS gears don't come with the shaft for the main gear.

Part #24?

[Dewmerz]

Correct 22, 23, and 24 fall under RF006 in the exploded view which is the stock gearset.

[EeePee]

the HS gears would have to include the shaft so people who damage it don't have to buy a useless (to them) low speed gear set.

And how do you think they'd damage it, cause it's awfully beefy.

[Dewmerz]

And how do you think they'd damage it, cause it's awfully beefy.

Nuclear bomb, semi driving over it, etc....Not sure. Maybe a set screw backing out doing some damage on the ends where the cups attach.

Piecing the axles together from part numbers right now you have to buy at least one low speed gear set to get the front. The rear is covered with the new shaft in the dig kit. I pieced together axles and am waiting on one more part to arrive before I put everything together.

[EeePee]

I pieced together axles

Oh, gotcha.

So since I have a dig kit coming, I guess I'll have a spare for the front. Ya know, in case a bomb goes off. :ror:

[EeePee]

Not the greatest picture, but I finally slapped some paint on the body. Took me two days, and whole can of black. Let it sit, forgot about it, went grocery shopping and it was in my way, then well, I took the window masks off and said to myself, "Self, that's kick ass! Take a picture!"

Kevin of course. Kevinlongisland. Owner.

I'm from Cleveland, and now I live in Columbus. But, I don't like football, but if I did...

I'm thinking the HB Rovers on the Eritex wheels might be the hot ticket for these things. The taller height will allow me to run the lower ride height I want to. I'm waiting for the Softs to be in stock.

[exesivefire]

Interested to see on how everything works out with the new gear sets..

We all know I cant drive, so I need throttle :lol:

Still wondering what the motor setup for these rigs needs to be, as someone posted the motor I put in mine lasted all of 10 minutes before it threw a brush.

Anyone tried a Novak Goat system in one?

This is the motor I ran in mine.

[saydee1800]

Please throw it in and let up know

[Dewmerz]

VXL setup won't work well without batteries capable of handling the amp draw. The VXL will immediately kick into reduced power mode if the voltage dips to a certain level.

I have a VXL, and I have a 5000 mah 3S lipo. That could work, but why would I want that big brick of a battery in my crawler? Maybe the 2200 3S will work alright with the VXL...

Or maybe just a 6 pack of GP3300s...

I agree. It is too hungry of a setup requiring a BIG battery. Something more efficient power wise while still putting out the torque would be better. A nice efficient 35T-55T brushed motor should get the job done with the high speed gears.

I'll be running either a 35T or 45T handwound Fantom motor (I have both) on a Sidewinder using either a 3S 1550 lipo or 3S 1100 A123 pack.

Should be a interesting test. Assuming a 5.25 tall tire, stock pinion/spur, and my math being correct the speed should come out something like this. The RPM is based on 3500 which is what I remember the VXL being.

LS Gear /2S Lipo (25200 RPM): 2.75MPH
HS Gear /2S Lipo (25200 RPM): 5.49MPH
LS Gear /3S Lipo (38850 RPM): 4.23MPH
HS Gear /3S Lipo (38850 RPM): 8.47MPH

[EeePee]

Hey! Finally got everything together, and made a quick little video of indoor back and forthing, and seeing how fast this thing is, and if it's going to cog or not.

And guess what!

http://www.youtube.com/watch?v=DsWxiJCXIi8&ftm=18

I love the whirling sounds of this thing. Sounds crazy. But the VXL doesn't have an instant reverse, so no way would I use it even if it did work awesome. What's weird is that it would roll a little bit after letting off. The axles didn't lock up like they did with the HH Cobalt Puller. Which would be a good thing for me, cause I like a slow roll more than a parking brake.

But again, I'm talking with Tekin to see if they have something that might fit my needs. And now that I know how fast a 3500 Kv motor is on a 3S lipo I can choose a motor. And I'm thinking sensored might be the ticket, not unsensored like the cog master Traxxas.

I have half the high speed gearset here (order two!), and the dig stuff.

[dkingston]

That video was... cog-a-licious "thumbsup"

[Rckcrwlr]

Now how are you going to get the tire marks of the woodwork...

[EeePee]

I get em all the way around the apartment. And at about 12.5 high, and 14 high and 16.5 high. :ror:

[killjoyken]

The HS gears lessen the braking effect and Tekin has a "push" setting you can play around with. But personally, it works fine for me. And really, what did you expect from a Traxxas esc? :lol: I'll stick with brushed. Even my Tekin RS Pro 8.5t sometimes cogs at startup in my Firestorm. Rarely, but sometimes.

That 3500kv motor is going to be overkill with the HS gears. :-P

[mike_d]

That 3500kv motor is going to be overkill with the HS gears. :-P[/quote]

3500kv is nuts! I just installed the HS gears and it is crazy fast with my 13.5 and stock gearing. I think a 17.5 or 21.5 brushless motor is going to be the ticket with the HS gears.

[EeePee]

The HS gears lessen the braking effect and Tekin has a "push" setting you can play around with.

Tried the Tekin's push, it didn't work as planned, it just kept the crawler moving along at low speed for a duration then stopped. Not like a drag brake in the sense that it gradually stops.

I think a 17.5 or 21.5 brushless motor is going to be the ticket with the HS gears.

I think you're about right. Novak's Goat with their 18.5 is rated at 2700 Kv.

I'm actually looking for something to work with the stock truck first. But even with the HS gears the stock gearing is at 71.6:1, my Berg is at 40:1 stock. The truck is freaking slow anyway you look at it.

[666]

To many years of engineering, that would have been perfect wheelspeed in o5-o6.

i wouldnt even think about running anything but a sensored BL system in anything that i run. if you are looking at tekin, make sure you get a sensored system or the goat system. there is also the novak sport systems, but im not sure if they will run 3s lipo.

Hard to tell if it is really worth the fight in the long run when it comes to the cost using the LSG's. Maybe in a year everyone will be running brushless with 50C+ rated lipos. "thumbsup"

Tekin RS combo: $270
Orion 3S 3200 Lipo: $120

the second option looks very practical, how long will this be good for before one needs to buy another combo though.
i am waiting for a used rockforce, new highspeed gears and a dig to arrive but have no idea on what motor and esc combo with pinions and spur to get the rig to a healthy pace. add to that the ? on wheels.

[Dewmerz]

I would not mind seeing something from Tekin for brushless crawling as long as it doesn't require a huge battery. I've had bad luck with Novak controllers the past few years and wanted to run sensored so I bought a Tekin RS.

[EeePee]

as long as it doesn't require a huge battery.

How huge? 2200?

[Dewmerz]

Small enough to fit on the front axle or on the upper links. Going with something like a 3S 2100 will fit on the front axle and would be able to handle a 42 amp draw. The motor would need to stay under this.

[EeePee]

Flipped the knuckles. Flipped the tie rod. Made a new short link, because the stock rod ends are big, and interfere.

New TCS delrin skid prototypes.

I ran it at the indoor place, and I ran only the long skid. I tried to get stuck, but this thing is slick. Me likey.

You can see I was dragging on the edges and the point. Can't say for sure, but I don't think I got caught up much at all.

So, I knew the truck was a lowrider. It was on the skid plate all night sliding along.

But I didn't know how low it really was. So I just measured. I'm used to driving a droop Berg, but not that stupid low.

I will post up on my thread..

[Truggies]

Thanks guys for all the info in this thread. I been looking at adding 1 of the RF's to my stable of Crawlers but was undesided on what to do with the new Losi soon to arrive. I now have 2 Axial based Gatekeepers which I love and a axial based Bender SWX I just finished building but have yet to test. I will have the new Losi as soon as they hit the street. I think that crawler is going to be a big hit.

As for the Kyosho RF would a 55T Integy and Rooster or Mamba Max esc Be a good setup, along with the HS gears and Dig.

Keep up the good work and keep the info com'en, More video is always good as well.
Thanks

[EeePee]

"thumbsup"

As for the Kyosho RF would a 55T Integy and Rooster or Mamba Max esc Be a good setup, along with the HS gears and Dig.

I would not go with the Rooster for one reason. Max voltage. It's limited (per Novak) to a 2 cell Lipo, or 7 cell Nimh pack. Personally I'd run a Tekin controller, but the Castle stuff is good too. Both of those will allow you to power the motor with more voltage, and that's a good thing.

[Truggies]

I run the rooster now with a 2s lipo and it does ok but I been thinking of switching to an esc that will let me go to 3s lipos. I been using 2s lipos sence i started in rock crawlen back in march of 08. they worked well so i kept on using them. But i need to switch to the 3s. Thanks again

Mine it going to be about the same with a little different set up.

Will post videos this weekend.

[EeePee]

How are the low speeds and tork with this?

Since it's a Cobalt Puller motor, the slow speed and torque is still AWESOME! The motor has got to be one of the best brushed motors on the market. Honestly. If not, I'll drop some teeth of off the pinion. 26 is still big kind of, and the final is ~50:1.

You nailed it...

I hope so, seems like it.

What servo have you found to work well with this dig. I am running a Hitec 7955TG for steering I was think about doing the same for the dig it only 10-15 buck more than the next lower one

[EeePee]

Oh hey, kinda forgot about this! Ha!!

I've got an Airtronics 361 controlling the disconnect. It's a 200 ounce servo. It's what I had, and as far as I'm concerned, you can never have too much power for any reason.

And with that said, damn this Cobalt Puller motor on a 3 cell lipo! :x

Too much power! :ror:

If I'm not munching teeth off the spur gear, I'm throwing the pinion gear of the motor shaft. It happens when I'm just dorking around or before gate three on a course. The motor shaft is still round, but never did I have this problem in the other trucks I ran this motor in, so I'm not modifying anything. I'll find a different motor, one not so awesome.

[BILLYGOAT]

i love the cobalt. but i had the same issue with the 5t cobalt and the 4600kv brushless motor i tried. i have a handwound 35t now on 3s and i think its just about right.

[saydee1800]

What gearing are you running now. I just put the high speed gear in at 84/23 and a 3s5000 lipo it was fast put my Tekin 21.5 sure did get hot!!!!!!

I have the stock 86 tooth spur, and a 26 tooth pinion with the HS gears for a total reduction of 49.6 to 1. I was aiming for a nice and even number, like 50. My AX10 is at 47.8 to 1 so I tried to get the Kyosho close to that.

I should have a 35 or 45 turn motor around here somewhere with a fresh cut on the comm, I'll stick that in there and see how it goes.

Me too, they're positively the best. I guess I could fiddle more.

I got speed, I got power, I gotta learn to control myself. :ror:

[microgoat]

Yeah the 10T heats up. It doesn't have that smell of hot, but it's warm for sure. But so are the worm gears, ESC and battery. I can feel the axle case is warm after a while, that's kind of weird.


Worms are inefficient by nature, but the biggest thing to watch out for is movement of the worm gear. Does the RF use a thrust bearing in the axles?


So I knew the truck would get warm by just by running it. What I didn't know was how HOT this thing got when you REALLY run it! Do NOT touch the motor or you're gonna scream. The skidplate was radiating heat, and more surprising was how warm the axle cases were! Heat from the worm gears! Weird!

So I thermal'd a crawler...

Got a temp gun you can shoot at the axles? If they're getting warm enough to feel heat, I can see explodage before too long...

It's not looking good. Killjoyken overheated a Holmes 35T at a 53:1 ratio. Sounds like those worm drives are very inefficient at the speed we want them to run.

They're inefficient at any speed, but they shouldn't heat up like that.

They definitely heat up. I may opt to pack the case with a good heavy grease to help dissipate any heat. Just not sure what to use...

[sparky0068]

Keep in mind that if you use too much grease it will retain heat. The objective is to lubricate without heat retention while still lubing. The best bet is to use a adhesive grease, and rebuild/lube frequently.

[dkingston]

My case around the worm gears has never temped above 90 degrees or about 20 degrees above ambient.

That was temping with an Exergen. Eee Pee has seen it.



- David

[Rckcrwlr]

On a normal run, mine doesn't go much more than that also. If I am bashing or testing...it will get up closer to 100

[dkingston]

Yup, now if you just grab a handful of throttle and rip around for several minutes (ala Kamikaze) you will warm those babies up. Truth be told, you will warm up Axial, Berg or any others as well (maybe not as much). Its just that nobody is temping them.


- David

[gimpygolden]

What kind of run time do you get on the 2200Mah with the puller?

[EeePee]

What kind of run time do you get on the 2200Mah with the puller?

In this truck, not as long as usual as I'm on the gas much more. But still long enough to finish three courses with some power to spare, I'm sure. Typically I'd say an hour or a little more, but again, in this truck, I'd guess half that.

I did recently switch over to an Integy 35 turn motor and a 84 tooth spur with the stock 18 tooth pinion which put the final ratio at 70.00001 with the high speed gears in the axles. The ESC runs a bit hotter than I'm used to it running, but the motor temps are cool. And since the ESC has thermal protection, I don't care if it gets too hot.

I just wanted a weaker motor so I can actually drive the truck for a bit instead of munching spur gears.

I also put Proline Badlands on Proline Epic wheels and have to say the truck looks pretty sweet. Like a 4 wheeled motocrosser buggy racer thing.

After a bit of crawling how many lights are flashing on the ESC? It has a built in temp monitor ya know.

I've had all the lights flashing before, and it kept working. Just cruise around for a bit and get some air flow over it.
