The small drive gear is glued in place and falls off quickly. I have had two of them last less than an hour. You also have to rotate the gearbox 90 degrees as the wiring points straight up and interferes with the body. If the gear were attached properly this product would deserve more than 5 stars.

Pinion gear comes loose with in the first minutes of use

I had the same problem as Chris , did not even make it off the bench

The Main Gear from the motor to the gears slips off during the work after one Drive forward and backward. That's really sad.

Simple plug and play including an incredible surprise at high and low end plus sheer torque at low speed. All this pleasure comes without any fatigue and total absence of the usual esc noise at any speed. Congratulation to this mind blowing product!
