I have a Turnigy brushless in runner motor plus prop, 2 Hitec HS-81 servos, and 1 Hobby king 40-50amp ESC for sale. All in working condition, sold as is. The ESC has some extensions i soldered on and the female plug is not on it, just a minor solder job and you can attach one. Never really used it. Could never get the Ardupilot to work and so now, after about a year, i figure it is time to trade my stuff in.
