Thanks Andy. I'm going to try the stock gyro with digital tail servo. Which one of the servo in xheli.com fit the bill..
http://www.xheli.com/servos.html? I'm also replacing the stock cyclic servos. I don't know what to order. I'm getting the lipo/esc/motor combo from xheli. Will my stock lipo that came with my G2 will still work? It is exceed 11.1 1200 mah. I don't know what the C rating is. Thanks in advance.
