Programming Menu 7 Instructions Correction
Some instructions sheets included with these ESCs had some incorrect information under
Programming Menu 7, #2, a & b. The corrected instructions are listed below. We inadvertently
listed as 8kHz PWM Frequency instead of Normal Mode in 'a' and 16kHz PWM Frequency instead
of Heli Mode in 'b'.
Programming Menu 7 – Operating Mode
The default setting is set to Normal (airplane) Mode, which is limited to a start-up rate of 0.25 or 1
second. Alternatively, the Heli Mode can be selected which reduces the start-up rate to 5-seconds for
the first start-up and any start-up after the motor/ESC has been stopped for more than 5 seconds.
This helps to prevent damaging the motor, gears or any other components from an abrupt start-up
when none of the parts are moving. Any time the motor/ESC has been stopped for less than 5
seconds in Heli Mode, the start-up will be immediate. This allows power to be applied immediately,
such as when aborting an auto-rotation attempt or for any other reason, to help prevent a crash.
Remember, you must wait more than 5 seconds after stopping the motor/ESC in order for the 5
second start-up to occur again.
1. Move the stick to center (between 1.4 and 1.6ms) for 5 seconds, and the controller will beep 7
times, indicating you are now in Menu 7.
2. Move the throttle stick to full throttle (>1.7ms) position to make changes to the Operating Mode
programming.
a. To select Normal Mode – You will hear 1 short beep. Move the throttle stick to center (between
1.4 and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or
leave in full throttle for 5 seconds to advance to the next selection.
b. To select Heli Mode – You will hear 2 short beeps. Move the throttle stick to center (between 1.4
and 1.6ms). The controller will beep 2 times, indicating you have set the program selection or leave
in full throttle for 5 seconds to advance to the first selection again.
