I am curious on the input side of our flight control boards were we connect our Elev, Aileron, rudder & throttle leads will the firmware/hardware accept a higher then normal 50 Hz pulse for lets say the aileron & elevator servo command but also at the same time accept a rudder input signal from the RX in the normal 50 Hz range?
I've carried out a quick indoors test to confirm if increasing the frequency pulse to 90 Hz on the input side of the flight control board would the system remain functional. The tri-copter performed great, it had a more rock solid feel for level flight and I had to lower the gain slightly on the aileron trim pot. However it did not resolve my tri-copter's slow auto recovery from non level flight to level flight (emergency recovery). Now I think the issue might be because of a feature with firmware 2.9 in non-acro mode that limits the end-point-adjustment (EPA) to 50% on the flight control board and maybe the Guardian module requires full TX EPA to perform an emergency recovery quickly. Have to wait until the weather improves to attempt acro mode which allows 70% EPA.
