I am trying out the autonomous landing mode available within Px4. The documentation states that: " Until
RWTO_NAV_ALT is reached the plane is held level and only rudder is used to keep the heading". The Nav Alt was kept at its default value of 5.
The problem is my airplane, a kadet, turns directly right after approximately 1 seconds and there is no rudder correction at all to keep the aircraft aligned with the runway. The log of one of the tests can be found below:
In the log one can only see that I initialize the take-off phase and directly abort it due to the fact that the aircraft is turning right. Moreover, in the log you can see that there is a small change in yaw response (rudder) but it is relatively small. I can find no parameters in Qgroundcontrol, which can alter the controller response on the ground which keeps the aircraft going straight.
More details about parameters values:
- I use the runway take-off mode. (RWTO_TKOFF = enabled)
- The gain of wheel steering and yaw rate is set equal to 1%/rad/s (I thought this would solve it)
Another issue is that I enabled RC stick override of auto modes, however, I was not able to use the rudder to correct for the heading error in the auto take-off mode using the RC.
Can anybody help me solve the above two issues?
