GAUI ESC programming
| Programming instructions for the GAUI SAE 12A brushless motor controller |
I had also requested the manual from the manufacturer, and they sent it within one day. Thanks, GAUI!
Note that the ESC calibrates the throttle range while entering programming mode.
Make sure that the throttle commands from the transmitter really reach the endpoints as desired!
The LiPo battery mode reduces engine power and turns it off, when the voltage reaches a point where the battery would suffer damage.
The NiMH mode turns off, when the voltage is getting too low for receiver and servos.
Below a flowchart of the programming features of said motor controller. It is used for example in GAUI EP 100 / EP 100 SE electric radio controlled helicopters.
The default settings are "LiPo", and "heli with governor off".
Comments regarding the governor:
- It can cause dropouts during flight, where the engine power is suddenly reduced to maybe 30 %. It may be possible, that the low voltage protection circuit triggers in LiPo mode.
- I experienced dropouts, when the throttle curve was not flat.
- The governor causes a small “wobble” in headspeed, and that can cause tail shaking. It's not like steady oscillation, as with too much gyro gain, more like random shaking.
- After landing and spooling up again, the headspeed was not the same it was in the first flight. I don't understand how this is supposed to work, and won't use governor.
Possibly this can be circumvented by setting to NiMH mode, at the risk of accidental deep discharge.
