Not sure who they get to build the RTR's or where QC is.
Unfortunately the stock spur gears released with this chassis are notoriously easy to strip. Upgrade to a better quality gear or even a metal gear if you don't mind the extra noise. Make sure the gears mesh properly (adjust with a normal weight paper between them) and avoid mashing the throttle and going straight from forward to reverse.
Ahhhhhhh, that would be what I did -- a couple of reverse slides to full throttle to slide it around. Thanks for the advice! I hope I don't have the motor mounted too tightly.
I just reread the thread, I didn't realize how many people were complaining about stripping the gears. I only noticed the dogbone issues. I checked that before running, and mine have very little/no play in them -- so I'm good on that front.
It still does have the steering issue. I trim it one way and then have to trim it the other way after driving for a couple of minutes.
This car is great though, I'm not going to be doing any racing so the steering thing is a minor annoyance. I can't wait until I can find a very wide open parking lot to try it out at full speed. Popped one tire's bead when bench testing full throttle with the speed gears and a 3s. Those tires start looking like pancakes!
What I thought was low speed gear slippage seems to match youtube videos of standard brushless low speed stutter, so I think I may have it adjusted alright. My son and I are just paranoid of that slipping/skipping sound, haha.
