This little truck is a blast. No regrets on the purchase. I did (still do maybe?) have 2 issues:
1. The front drive shaft was not securely connected to the diff. It came off during my first use. I disassembled the front end and put loctite on the screw that connects the drive shaft to the axel. So far that has worked. I was lucky to find the front half of the driveshaft on the ground.
2. I could not get the motor to respond to input when I first turned on the vehicle. While trouble shooting, I found that one of the 3 wires from the motor was not seated in the plastic connector. It has worked fine since I corrected that.

I would purchase this again, but I think some better quality control would benefit those less inclined to tinker with things.

Nice kit, but space is tight in the chassis. Every nut has blue loctite which is good, except they didn’t loctite the diff input shaft to the pinion gear. It came apart during the first 10 min and launched the input shaft and half the driveshaft. So still check all screws and nut before use.
