Hey the truck has a vibration in the tranny? Common with plastic gears? Just ignore or should I look for bent shaft or messed up gears?

I had a similar problem with a noisy tranny. It wasn't improper meshing of gears. Turns out the pinion gear set screw was contacting the spur gear teeth. I'd check to see if that's the problem.

I was super disappointed with how easy these trucks get stuck last year when I got mine. Coming from all 1/10 scale equipment that is WAY heavier and runs tires nearly twice the size, I guess I should have known but I was still like WTF? Anyway, at the urging of some friends I locked the rear axle to try it and it works much better. I just used hot glue and it is holding up fine so far, the best part being that with greasy gears the glue doesn't stick. It cools and takes the shape of the teeth but the pieces just come out when you take apart the diff without any fuss(I didn't have spare spider gears to use). Chaseracer has both axles locked permanently in his Autocar dump truck and it still steers fine loaded on dirt. I will be locking the front tandem in both my trucks too in the near future just to try it. My Hayes also gets better traction than my KH because it has my own springs and the shocks removed. Like Rob said, if you tighten everything up properly it won't articulate.

I also had the same issue as Mario with a smaller pinion I swapped on. I had to shim the motor back for clearance so that the set screw didn't hit the driven gear. Luckily for me I remembered his experience first and shimmed the motor prior to running it. May not be your issue but it's worth a look.

"Ok which one is better for dirt roads and uneven surfaces? Axles with lockers or having front wheel drive? Obliviously front drive with lockers all around is best but I have rear (2) and front drive axles for the dumper build. But would have to purchase locking axles. My thoughts are for building the Aeromax dump truck with lockable rears and just stock front. Figure if it gets low on traction I can lock and still be able to have a good turning radius when not locked. Is that what you guys are doing?"

Cooper, if you haven't read through LMACKATTACKS build thread on his ten wheeler dump truck it will help you decide how to set up your dump. http://www.rctruckandconstruction.co...ead.php?t=7706
I drove this truck for about 2 hours at the RCTandC spring meet and had a blast. It would go just about anywhere in the sandy mixed dirt. I'm currently building a dump using a TLT front drive axle with a scale 72.5" tandem spread based on a Hendrickson walking beam suspension. The steer axle is locked and the rear rear drive is also locked. It will have a scale 19' bed. This was based on things learned from LMacks build and the spring meet in Ill.

We need more animal pictures in this thread!

Sorry forgot to say nice job on the Areomax! I like the color.
