I am using a RCtimer Pixhawk with RCtimer power module (6S compatible) along with a 750mm X8 frame and DJI E1200 standard propulsion system running on a 6S 10,000 multistar pack.
Running 3.3.3 latest firmware.
Futaba 8FG controller with 6303 SBUS receiver.
Using 915mhz telemetry also.
Fairly new to Pixhawk in multirotors but have used them in fixed wing.
The multi's I have used the Pixhawk in did not have DJI motors/esc's.
I went through the wizard and setup all parameters.
Everything checks out OK and initializes fine.
Tested motor directions and they are good. Had a bit of trouble decoding the ABCDEFGH motor test but ended up finding the required information.
Held down the unit to triple check rotation and inputs.
While in stabilize mode with me holding it down so I could test input directions and only raising throttle maybe 10%, the motors rapidly start to increase speed, enough to make me lower throttle not knowing if it is just going to rocket off while I am trying to hold it down. Did not feel safe at all.
Makes me worried that I will have very sensitive throttle control.
Tried taking off in ALT Hold mode and as soon as I get above 50% throttle the 2-5 motors starts to slow down and the whole unit starts to shudder so I cut the throttle.
Log files attached, hoping someone could shed light on what is happening.
