If any one is interested in getting a fix for their tail, the ep50 motor from GWS is amazing. It is a direct drive motor, so you will have to use the DD props. Everyone that i've done that for has met with remarkable results. Your tail rotor control will be wonderfully impacted. If you purchase the GWS motor it will come with motor, diode, and mounting screws. You will have to do some Slight MODing on install to achieve a perfect fit (10 sec worth), But your going to love it.
