Greetings you as a supporter of the internal combustion engine!
Check out my post here Testing of the aircraft with the HOLYBRO DURANDAL flight controller for resistance to large vibrations . The problem with using an internal combustion engine is its vibrations. I had no problem with the airspeed sensor. I performed a test of the aircraft without measures to eliminate the influence of vibration, my goal is to establish the stability of the control system to the appearance of vibration, it was to check the flight controller for how much it itself is provided to this effect.
