I've just replaced an apm 2.6 for a pixhawk in an x quadcopter, main characteristics are:
The fact is i'm doing bench tests with propellers pushing down to test throttle response to input and i get something like the log attached.The first one is almost ok but in the others output 1 is completely flat. I was wondering maybe due to a slightly pitch up attitude (not more than 2º).
Please if anyone is having or has had some similar behavior please contact me. Just a little bit scared fly this giant in these conditions.
Thank you very much
