I am using the E-flite 25-Amp Pro Brushless ESC, and when i plug in my 3-cell lipo, the esc gives off 1 long beep followed by 3 medium beeps. According to the ESC manual, the esc should be armed, which it is, as I have ail, ele, and rud responce, but NO throttle response. I occasionally get the motor/throttle to work, but have no idea why it worked. Any help/hints on what to do would be greatly appreciated. Thanks - Justin

Are by chance using a Futaba (and maybe Hitec) transmitter? I recall that for non JR transmitters the E-Flite ESCs require that the throttle channel be reversed. Not having the proper travel will prevent the motor from starting...
