Differences Between Axe CP and CPv3 Tail Motor

The tail motor in the Axe CPv3 is ungeared and runs at a very high RPM, because of this, I’ve already burned out two motors at a very pricey $24.99 a piece. I’m sure these cost Helimax $2 each, but they overcharge for all of their replacement parts. They hook you in with an affordable helicopter and then get you when you need to replace parts. This is one reason why I’m looking forward to moving up to the T-Rex 450, because replacement parts cost about half as much.

Anyway, the last time I burned out a CPv3 motor in my Axe, my local hobby shop didn’t have the replacement motor for the CPv3, but did have the CP version with a brass gear on the end. They assured me it was the same motor, but when I got home, popped off the gear and put on the prop, I realized the shaft was much shorter than the original motor. The prop still fit on, but I’ve lost two props now, on a hard landing where the prop pops off and slams into the ground, breaking. I don’t think there’s any way i could further secure the prop, so it looks like I’m just going to have to replace the motor again when I get around to it. Anyway, Make sure if you replace the tail motor to wait for the correct one.
