Reject Position Control message on Helicopter


Currently I’m building GAUI GX4 helicopter with modifying Blade 130 mixer.
First flight was OK, but it is very unstable to control.
So I’ve tried to change “Posion” mode, but PX4 did not allow this mode with “Reject Position Control” message.

Anybody can confirm if PX4 can not support posion mode in helicopter or not?

This is due to version mismatch between QGC 2.7 and PX4 1.7.3.
After upgrade to QGC 3.3.1, it works fine. Thanks.
