Hello everyone! I am currently trying to setup an electrical hydrofoil craft built from 3D-printed plastic. I am using Pixhawk Cuav V5+ and latest update of arduplane. All servos seem to work well to adjust roll, pitch and yaw. But I am having some trouble with my propellers and ESCs.
First: I use ESC: Hobbywing platinum v4. 60A with Super BEC 5-8V plugged in on the rail on the pixhawk. There is also an additional cable on the ESC for RPM that is currently not plugged in. I have 2 propellers plugged in on M1 and M2 as “Throttle”. Min/max PMW for both servo outputs are currently set to 1100 and 1900.
The problem that I have is that when pushing throttle up, the propellers first start to turn at around 1450 PMW. And the biggest concern is that they accelerate up to the right RPM very slowly. It is not responsive at all. What could the problem here be???
My second concern is that I would like to implement a sonar sensor (that I have already successfully implemented in range finder, seeing acccurate values) to control the height of the vessel. My thought (that I am not sure if it works in arduplane) is to somehow set at what height the vessel should fly, and that propellers and flaps will automaticly control to maintain this exact height, creating a smooth ride. Is there someone out there who knows how to do this? Please see pictures attached!
Thank you in advance!!!
