Re: From the "tub up"
 

Droop may not be the best word but it looks like its lacking travel for sure. Here's a couple pics of my shocks @ ride height, full extension, and compression. It doesn't look like your shocks are extending when the wheels are off the ground. https://uploads.tapatalk-cdn.com/201...ddfc6b3de5.jpghttps://uploads.tapatalk-cdn.com/201...cbf104420e.jpghttps://uploads.tapatalk-cdn.com/201...0b31b41f87.jpg

Re: From the "tub up"
 

Does the suspension travel smoothly? Is anything binding? Here are those same shocks on the rear of a Wraith. Its obviously a bit different but they have full travel...https://uploads.tapatalk-cdn.com/201...4c808df8a8.jpghttps://uploads.tapatalk-cdn.com/201...fc647bf27b.jpghttps://uploads.tapatalk-cdn.com/201...af2e7c3514.jpg

Re: From the "tub up"
 

Thanks for the pics, they help.
I futzed with the sway bar, seems to help a little. Plus the shocks may not be filled properly...gonna check them tomorrow.

Re: From the "tub up"
 

So I have to use the longer plastic body posts bending them slightly to attach the cage because the Luxury panels aren’t a perfect fit and the reservoirs just barely clear the cage. Ordering power plant tomorrow :ror:

Re: From the "tub up"
 

I bet your excited to get that rig out for a shakedown!!

Re: From the "tub up"
 

Totally excited! Venom LiPo 3S 11.1V 5200mAh 50C Is on the way.
The MMX intimidates me a little though.

Re: From the "tub up"
 

What gearing will you be using? Would you not want to run 4s with the 2100kv motor and the MMX?

Re: From the "tub up"
 

I was planning on 16/64
Would 4s work well with the combo I’m using?
I’m a novice so I’m open to input and ideas.

Re: From the "tub up"
 

I'm a novice at brushless motors myself, but as I understand it, the motor rpm is a factor of the kv rating and the battery voltage.

I got the impression earlier in this thread that you wanted some speed (vs crawling); if you are looking at getting the wheel speed of what you would get with a 3s battery and a 3xxx kv motor you will need to gear up or volt up (go to 4s) with this motor.

Someone more knowledgeable can chime in if I've missed something here.

Re: From the "tub up"
 

You are correct sir"thumbsup"
4s will still be well below 50,000 rpm max spec’d for 540XL 2100KV
Ordered SMC Factory Spec 14.8V 5600mAh 60C
Motor should be efficient and not overheat.
Recommendations on gearing?

Re: From the "tub up"
 

Why? Setup and programming? Hooking up the aux wire?

Re: From the "tub up"
 

Set up and programming I should be okay. Not sure what to do with the auxiliary wire and this is my first sensored motor.

Re: From the "tub up"
 

for the yeti the rock racer/crawler mode is really nice. i have set it to a seperate channel so i have up to 20% dragbrake race over crawler mode. some hock it to the shifter so 1. gear crawler and 2. gear race mode. crawler mode fwd / rev race fwd / break / rev.

regarding gearing start with the planned stock gearing 16/64, but you can go up with pinion i run the 3800kv on 3s with 19/64 no issues. take a temp gun to check temp while testing.

Re: From the "tub up"
 

Had to butcher the battery tray in order to accommodate the sensor wire and give the two speed linkage room to move. Probably will end up using Velcro straps to secure battery. So far it’s rolling smoothly on the floor :mrgreen:

Re: From the "tub up"
 

With the 2-speed and 4s power you probably have enough flexibility to just start with what you have, and go from there.

I can imagine using the data logs from the MMX for temperatures and motor RPM to fine tune things, but I'd start with just getting it out there, and see if you can manage the wheel spin. :)

Re: From the "tub up"
 

As for sensored, the connectors are not waterproof, so make sure you've coated them well with dielectric grease. My Tekin motor included a tube of this stuff.

For the aux wire, I recommend connecting it in parallel with the servo for the two-speed transmission. This way you should not find yourself accidentally letting off the throttle on a speed run, expecting the truck to coast to a stop, only to find that the drag brake engages instead. :shock:

Test it first, but I expect that this will require a servo reverser such as the Expert Electronics EXRA320 with integrated y-cable. The reverser is needed if the third channel engages crawler mode on the ESC while shifting into high gear.

If you find that you don't need the reverser, you can make or buy a simple y-cable.

Re: From the "tub up"
 

Ugh!! Was MMX a stoopid:cry: purchase? It won’t fit on either ESC mount. I’m looking for creative help.
I could always use it in one of my YXL’s but really want it for this project.
Some of you have been really helpful (you know who you are) , searched but could find a solution.

Re: From the "tub up"
 

It's probably overkill for the yeti, but then so is 4s and the 2100kv motor. :)
1) use GOOP to fasten the ESC to the flat ESC mount, leaving only the front and one of the side screw holes exposed. There is not a lot of mass here, and two screws should hold it well enough. I only use two screws on my yeti, having made the pan too narrow to use both sides of the mount.

or 2) fasten the flat ESC mount in with three screws, and then attach the ESC to the mount with this stuff, from Home Depot:

Re: From the "tub up"
 

+1 use the flat one and then outdoor double sided tape to mount and a zip tie to secure it. i use tesa outdoor tape tesa Powerbond® OUTDOOR - tesa great stuff "thumbsup"

yes the mmx is overkill but i like overkill electronics, cause they never run at their limit :mrgreen:

Re: From the "tub up"
 

I bought a separate mount for this: https://www.amazon.com/dp/B01J4MG1OS

Works like a charm, with a bit of Xacto-knife surgery. I originally tried just mounting it with some servo tape to the flat mount, but it kept coming off. Much more secure with this Mamba ESC cage.

Re: From the "tub up"
 

Thank you!
I went ahead and ordered it.
Can you share a pic?

Re: From the "tub up"
 

Ok, so mounting the MMX is going to be a PITA! The holes on the RPM plate don’t line up. I’ll probably glue the RPM plate to the stock plate and go from there.

Re: From the "tub up"
 

Double tape and zip tie :mrgreen: easy cheap and clean. no pita 8)
just use the correct double tape mine is so sticky that if i have to remove the mmx i'm afraid to break the housing "thumbsup"

Re: From the "tub up"
 

Awesome! Thanks :)

Re: From the "tub up"
 

But you have to remove the paper on the bottom of the mmx if using double tape to mount. my fault i forgot it first time and on a huge hit my mmx came off. sticker was still hold by the tape:mrgreen:. that's the reason for the zip tie just in case 8)

Re: From the "tub up"
 

Sorry, I'll try to post a pic tonight, but the holes lined up perfectly for me. Just my motor mount was in the way, so I had to trim a corner off the ESC cage, and remove one of the mounting points for the ESC switch (there's a mounting point on each side. Just pick one, and remove the other one). What sorts of issues are you running into?

Re: From the "tub up"
 

Thanks for your input. There was no way the RPM was going to work. $10 in the trash :cry: nothing lined up nothing fit. Going with Scotch Extreme fasteners on stock mounting plate.

Re: From the "tub up"
 

Ugh! So close! I need help please. I’ve been at it for days.
I’ve got everything installed and mounted,gear mesh is good,2 speed action is good. End points seem to be good, I can change gears by hand easily. Everything turns by hand and rolls across floor smoothly. When I connect battery servos and motor fine but the pinion just spins spur and I can’t get the clutch to engage. I’ve tightened the spring 6-8.5 mm, even tried completely tightening it. Haven’t had this problem with my other rigs so I’m stumped.

Re: From the "tub up"
 

What do you mean by “getting the clutch to engage?” Are you not getting power to the wheels? If you spin the spur manually do the outputs spin?

Re: From the "tub up"
 

I can spin the spur easily by hand and it will spin the transmission shaft turning the wheels.. Under power the spur spins but doesn’t spin the transmission shaft.

Re: From the "tub up"
 

I’m not sure what spur your running but in the pics on page 3 or 4 it looks like you have both the original style slipper plate(flat washer looking ones) and the vented slipper plates installed. I’d take the washer style ones off and only use the vented style then give it another shot.

Re: From the "tub up"
 

to check the clutch adjustment put it on the wheels and tide it up to the point where you barley can move the spur. then a little bit more till you can't move it. that's how i did it. all with out movement on the tires.

Re: From the "tub up"
 

I don't know what you had trouble with using the rpm cage. That is precisely how I have my MMX mounted in my Yeti. Works perfect. Everything lines up without issue. I might have had to shave the corner of it like roach said, can't remember.

Re: From the "tub up"
 

I’m recovering from surgery.... will address mounting esc and clutch issues in a week or so.

Re: From the "tub up"
 

Ouch! All the best! I hope you're doing fine.

Re: From the "tub up"
 

Me 2

Re: From the "tub up"
 

I’m baffled :x
I tried without “washer style plates” part# ax31059 ,still no go. I’ve tried completely tightening slipper spring, no go. 2 speed transmission shaft spins freely both directions but when I put everything together and apply power, no go, spur just spins.
http://www.rccrawler.com/forum/attac...1&d=1509825508
What am I missing?

Re: From the "tub up"
 

Last piece on the right, you should have 2.

I had tons of problems with my slipper setup on the YXL, and it uses the same slipper parts. The fix was a robinson racing yeti gen 3 slipper set up."thumbsup"

Re: From the "tub up"
 

On the back of the slipper pad is a doubletape. You have not glued the slipper pads to the spur.[emoji41]
