Rock Force Build with some Cow Bell... [Archive]

I was so intrigued by this rig that I just had to do it.

The idea of worm gear diffs made me take the leap.

Well, I picked it up at AB-C yesterday. First impression when I opened the box was good. Only disappointment is the wheel and tire selection. These will not be good for anything but bashing. They are a wheel with a real soft tire and no foams. :shock:

First thing I noticed is you better make sure you have gear grease, thread lock, etc. This kit does not supply these items. A good grease is very important being that wormgears are known to heat up with excessive running. I am using RC4WD's Monster Lube.

Instructions are very clear as Kyosho has always been good at.

So let's start with these axles... The gears are heavy metal...great tolerances...

The axles are set up pretty neat...the drive cup is enclosed in the axle case and then there is a dogbone that comes out to the stub axle...

http://i139.photobucket.com/albums/q307/rckcrwlr_bucket/RC%20Items/RockForce/RockForceBuild001a.jpg

These dogbones are massive...look at the compared to TLT's

http://i139.photobucket.com/albums/q307/rckcrwlr_bucket/RC%20Items/RockForce/RockForceBuild002a.jpg

Both axles are build...these things are heavy and bulletproof...

Now comes the tranny or should I say the motor mount with a spur gear. To explain this, with the wormgear, all reduction is in the axles. This eliminates torque twist and also gives you the best drag brake around.

My first plan was to throw in a 35t warrior...they actually recommend a 24T. I figured, what the heck...and through in a 7T Puller... :wow:

http://i139.photobucket.com/albums/q307/rckcrwlr_bucket/RC%20Items/RockForce/RockForceBuild007a.jpg

The chassis consists of the Tranny? and several plastic cross supports.

The driveshafts are an interesting design. They consist of two half shafts, a hex shaft and an aluminum sleeve. Great design.

Axles are on the chassis...
http://i139.photobucket.com/albums/q307/rckcrwlr_bucket/RC%20Items/RockForce/RockForceBuild012a.jpg

Shocks are a nice set up. The fronts are shorter than the back for better function. The come with aluminum caps and plastic bodies...they do offer an aluminum body upgrade. I am running 30 w Oil in them...

The place where they tell you to mount the ESC and RX is two cross bars...I attached a piece of lexan to make it easier to mount.

The wheels and tires had to go...

I got my Mayhem Dbl Phattys with Rock Crusher tires and Kreepys. These things are heavy will be just add to the planted feeling...
Problem is that the RF has larger axles so I had to get the drillpress out and open them up...

Findings...

The Puller is definitely the way to go. It gives you all the torque and still wheel spin. I may try a 4s to see if I can get some more top end speed.

I will definitely need a softer tire. Actually may give the OEM tires a try with some foam in them. They are pretty soft.

Waiting on the dig set up. We're having a Test'n Tune this Saturday so I will know better then.

Need to get another body for comps though... :-(

Well the wheel/tire set up is terrible.

I needed a set of wheels with negative offset and was ready to order some when I remembered my DNA Stalkers.

They put the width at 10.75"...perfect.

Now what tire...I opted for M3 Hammers on the front and M2 Hammers on the back with ProLine Memory Foams.

I am thinking this is the combo...we will have to see...

that would not make it legal.... the body must be its stock unaltered width in the cab area.
i do not see stock or unaltered any where in that rule, it would be full original width just with a bend to make it wider. I dont see anything in that rule about making a body wider..
2.1.2.1 – Super & 2.2 Class body must be 3” minimum height on sides. No less than 12.5”
total length and full original width, and no less than 5” in the center. All bodies should
resemble its original form (Jeep bodies look like a Jeep)

is that one of the rules on the super secret set of rules??

Well...I got to run the RF today at the comp...

Only thing I changed this time around was I cinched the suspension so that the Panhard Arm was horizontal.

Sitting a little to low with the lack of wheel speed but other than that...I was very impressed with how well it was planted. The only place that stopped me was a breakover that highcentered...all of the sidehilling, verticals and manuvering was great. Hope to have the dig and HS gears by next run...

This is on 3S LiPo...charging a 4S now to see how much more I can get...

Temps were right in line also...that dig is smooth, once you dial it in...Still working on that...:roll:

looking good, did you do any modding to fit the DNA wheels ? i have been in touch with DNA for those and still waiting for a response.

Thanks...

No modding needed. I had these from my 2.2 Clod. They work perfect...drilled airholes...can't wait to run it at the comp on Sunday...

Will update

It helps a lot if you don't forget your TX to an event...so I finally was able to get some wheel time...
until my spur gave in to the 4S LiPo :oops:

90T Spur/25T Pinion, 7T Puller, 4S LiPo
(Houston...We have Cowbell)

90T Spur/25T Pinion, 7T Puller, 3S LiPo
(Delrin Skid makes a world of difference...and still Cowbell--Slick and Speed, what a combo)

I had the 90T on there from imploding the OEM one at a comp and that is all they had...I think I am going back down to the 86T...and staying with 3S LiPo...

i noticed some here have been using the stock spur and getting good wheel speed with 26 pinion, i might use a 25 on stock spur with 3s. pinion option is because i am still waiting in 26t i ordered. will let you know how it goes.

Ran it today at the GTG...

Love the wheelspeed....

87/25 gearing
7T Puller
3S LiPo

10 min run yielded motor temps in the 190's and that great electrical smell. Need to look at another option for a motor.

Handwound 35T??
Handwound 25T??

What do you guys think???

dkingston

01-25-2009, 07:54 PM

I think I would go to a 23 to see how the temps come down. I think you are just overgeared.

JMHO ;)

dkingston

01-26-2009, 06:20 AM

A lot is going to depend on the motor AND the combo. A 55T, with 86/23 the motor never gets above 100 degrees.

Having a nitro race background and some of the required paraphernalia necessary has been handy in crawling. This is the temp gun I use.

http://www.asturmodel.com/images/big/exergen.jpg

Infrequently, I will check my speedo, motor, battery and on the RF I initially checked the axles at the worm to make sure there wasn't heat buildup there. I would not recommend getting something that expensive, but there are some much cheaper ones out there.

This one is available from tempgun.com for under $25 (I think)

http://www.petgadgets.com/Images/PetTempLarge3.jpg

When not using it for your RC habit, they are handy for other things around the house.... Uhm, like well, lemme think... well you will think of something! "thumbsup"

I have a Raytek (http://www.raytek.com/Raytek/en-r0/ProductsAndAccessories/PortableThermometers/PortableThermometersSeries/MiniTemp-AutomotiveHandheld/Default.htm)...a must have in the pitbox whether Nitro or Electric.

I was thinking of going 2 cell to see if I can lower the temps without changing gearing.

Time for some Temp Tuning...

I dont think you will be able to reduce the temps enough. The voltage drop will have more of a detrimental effect than changing gearing...

Change the pinion first... I think that will help you a bunch!

- David

01-26-2009, 12:58 PM

Yeap...change one thing at a time... ;-)

I'll run for a set time and then take a temp...change to a 23T Pinion and run the same time and see where the temps went...

i had a problem with temp in my motors too, fried 3 different motors. switched to a 21.5 goat system and everything is good now.

thanks dezmoon.

I'm thinking of running 7t puller on 3s A123's 2300mah. Do you have any idea of run time on that? What batts have you ran on your setup?

Honestly, I don't think the 7T is the right motor. I am changing to the Novak 21.5 Brushless.

I saw Dezmoon run with his and there was no heat at all.

As soon as the motor comes in...the changes will start.

Rckcrwlr

04-02-2009, 04:39 PM

Well...here is what I am starting with...

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover001.jpg

A Rock Force that is showing potential but needs some tuning...

Add an Xtreme Racing CF Chassis
Add a Custom Dezmoon BTA Steering assembly
Add Panther Cougar Tires
Add Novak Goat ESC with a 21.5 Motor

What do you get...

The RckFORCE!!!!

Rckcrwlr

04-02-2009, 04:40 PM

First is to introduce you to the new chassis...

Xtreme Racing Carbon Fiber Modified Chassis

I wanted to keep the integrity of the RF so when I saw this chassis, it was all for me.

Check out how the "fat" was removed from it...this is how Kyosho should have done it.

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover004.jpg

Also notice how there is another row of holes for shock mounting above the OEM Chassis

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover005.jpg

This is the Novak Goat Crawler ESC matched with their 21.5 Brushless Sensored Motor.

The stock RF sits at a 11.5" wheel base.

That needed to grow so off with the rear links and in come the Delrin...

Get the delrin 5/16" stock and measure it to size.

This stuff is slick so make sure you clamp it good...

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover009.jpg

Drill the holes for the rod end allthread to go in. (sometimes you can get away will not tapping the hole)

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover013.jpg

I added a little more than 3/4" to the length of the lower links...

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover007.jpg

Here are the upper rear links
http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover014.jpg

This resulted in modding the drive shaft so I cut one of my allen wrenches to get it to work. The fuel line will keep the hex shaft from pulling completely out of one side or the other...

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFMakeover008.jpg

All put together and it is now sitting at just under 12.5"

I was running Proline Hammers last year during the testing mode.
This year I am going with Panther Cougars with their stiffer foam to help with sidewall strength.

These really change when mounted on my DNA Stalkers...With a 1" width...I like the why they look...

Well...she is pretty close to done, so I figured I will give you a sneak peak.

The wheelbase is perfect now...running a longer rear will help with verticals. The chassis gives me more adjustments and also better geometry. The tires give more ground clearance and a softer compound.

The Novak System is in and ready to be programmed...

http://i265.photobucket.com/albums/ii209/wpac-rc/Builds/RockForce%20Make%20Over/RFRevamp-004.jpg

Only thing I need to do now is fab new mounts for the panhard. I would like to have it as horizontal as possible.

Mine worked fine...I use the Kyosho Tool with no problem. I am going to change to regular nuts to eliminate them sticking out.

Finally got back to the RF.

My next thing was to get the Panhard more horizontal. I used some 1/4" Delrin to fab the bracket.

Here is how it transpired:

Made a template based on the OEM bracket

Nice

I really wish there was a way to get more articulation out of this rig. I feel it is more like a tank than a crawler

I really think if the front shocks were more on an angle it would help.

I know switch to a berg untill my rock force is better. I need a chassis
