Turbocharged the RC that I had put this in. It was a brushed setup before. This thing was soo powerful it ate the plastic gear in the rear diff almost immediately accidently 😂. I turned down the power a little and it's a rocket now and the kids love it. Would definitely buy again for another project!

Very fast delivery, fits in my LCG chassis like it was made for it. Just installed it this morning. Would like to have seen it come with a IC3 connector instead of a 5, since the 2s Lipos have the IC3 on them. Other then that, looks like it's going to be fast as hell!

Put it in my Arrma infraction mega 1/8 scale and it's quick. Kicking up rocks and moving.

This things a beast! Way too much power the truck just flips itself over from a full stop. Lotsa fun definitely recommend

Ordered this for my losi 22s Roller no prep drag car. It originally came stock in the car but 0 fitment issues. Exactly what I was expecting.
