Note, if your throttle reverse setting in your TX is incorrect, it can cause the Programming or operation of the ESC to not work properly.
You must be in the "NORMAL" switch setting and not "3D", "Throttle Hold" or "IDLE Up" switch setting.
Your Throttle curve in the "Normal" switch setting must have 0 value for first value in the throttle curve1(stick low) and near 100% value for the final value in the throttle curve (stick high)
If your swash is repsonsive to your cyclic stick but your esc is still beeping the motor, it may not sense the throttle limits correctly. Reset your throttle limit into the ESC memory:Settings I use w/ my Blueray 450 helicopter:
Brake : off
Battery type: Lipo
Cutt off : Soft Cut
Cutt off threshold : High
Start mode : Super soft start
Timing : Low (alternatively you can use High timing, some people have experianced problems with Med timing on the Alpha motors)
