Thrust decrease during transition

[Sejin_J]

Hello all

I’m testing a y-3 tilt rotor using px4. (E-flite convergence airframe)
My plane is good at transition. But I looked at the flight log and found something strange.
I did almost 100% thrust but px4 didn’t keep the thrust at 100%.
Here is my log image.

The upper graph’s black line is my control input and lower graph’s black line is actuator control.
I want to know why that is.

Have a goooood on

Hi @Sejin_J

I think during transition you can’t control the throttle directly, as the vehicle by itself is trying to keep altitude constant (altitude controller running). So probably you only need roughly 40% throttle to keep it, as also the wings start using lift.
