For those who maybe having problems with a "lefty loosey, tighty righty" car:

Please check your swaybars. I was having the same problem at the track, and I was sitting there racking my brain trying to figure out what was wrong. A friend took a look at my car and noticed that my swaybar was "skewed", one side was pushed more forward than the other. Re-adjusted my swaybar and voila! Problem solved. Also check the fit on the ball end on the arm. Mine was a bit tight, and I had to "work" it a little to get it free. Just some food for thought...

I just got a Pro 4 but have a few questions about shimming this thing. I'm used to the R2 which was much more simple (IMO) than the pro 4 as far as the gear boxes go. Granted, it can be different for other people but how do most of you guys have the pinions and gears shimmed? I have a two diff setup and shims are as the directions say. Just looking for some tips or anything I should do differently.

i assume your talking about the pinions inside the gearbox, best is to shim per instructions and readjust if its not right, for me i had 2 extra in the rear and one more in the front.

I also shim mine as the directions say and run 2 diffs. The only time I stripped a gear was when I ran the one way. Once I started running 2 diffs I have not had any problems and the transmissions are super free. Couldn't ask for much more from the car.

Yes, inside the gear boxes. I'll do as the instructions say and go from there. I actually just received the car today, I purchased it from rblove and I just had to tear it down to see what makes it tick.

Is it possible to torque down the diff cases too much? I tend to overtighten things on a regular basis.

Now I have to get another cuda cause I have a ton of parts lying around for it!

i too have a bad habit of overtightening things,

write now the diffcases seem to hold up due to really dense material used, but i only red screwed the diff about 3 or 4 times...

Not quite sure I understand... you're running two more shims on one side of the one way to push the one way into the pinion more?

Thanks, it's really a nice kit, I'm pleased with the construction and this BMI chassis I got with it is really awesome.

I didn't notice any ill effects from tightening down my diff cases. Not like the TC3 where you need to watch how much you tighten them or they bind up.

Rob's car should be killer for you. Wonder what car he is going to run now?

I'm not sure, I hope he sticks with RC, it seems many are taking a break lately.

Too bad as Rob seems like a good guy. My buddy Mike use to race with him a few years ago.

You still running your Cuda? If so how do you like it? Was almost thinking of getting a R3 or a 415 for a 2nd car or my main car as HPI parts are still kinda hard to get. Speedtech always seems to R3 parts in stock or has them in a week or so.

No I sold my R2 and I miss it but I just wanted to try something new. I'm getting a red R3 in a few weeks, as soon as my new job pumps out a few paychecks. (don't tell my wife)

Oh here's a question... I have the diffs out in front of me and I can rock the gear back and forth a bit. Is this supposed to be like that or should I just crank it down a bit more?

Tighten it. The gear should not be able to move between the outdrives....... Glad to see you are rebuilding the car to learn it and get it all fresh. I had not rebuilt it since I converted to that chassis............. Rear gear might have been bad. Started making noise last time out, but I threw a new set in that box for ya. Hope you enjoy it....
