Well I love the quality of the Rc-motor mount. No flames toward you guys. But I think it flexes or the frame does because your can see the gear seperate front the spur as I gun it (holding in hand of course). Aside you can see the vibration created with the flex which caused the rotor to snape off the little 1/4 hv 4.5 motor. Aside from braking the rotor shaft, I can't be the only one that notices this? Its as if we need something holding the tip end of the shaft in a bearing with the trans? Or bracing the motor mount better to the frame. Anybody?
