The gyro upgrade seems to have shortened the life span of the tail motor a little bit. After going thru a couple of tail motor, they did not fully die they just slowed down to a point that it slowly spins to the left even with full right rudder, I decided to experiment on the belt upgrade. I bought parts for the 'blade cp' belt mod and with a little machining and fabrication I made it fit the AXE, I also change the main gear to a t-rex to have more options on the pinion gear. It is nearing completion I am just waiting for the new idler pulley because the first one is too big. If any one is interested I will post pictures when completed.
