No collective control

[akabud]

I have a Trex 550 I've been flying with the Spirit with no problems.
Now I'm upgrading the TX from a DX6 to a DX9. Now the collective does not respond. The throttle works but no pitch.
All the servos work with cyclic stick. The pitch responds in the Diagnostic Tab. The Tx monitor shows it working.
Pitch curve is 0 to 100.
What else can I check?

Hello,

Bailout is activated all the time. Check your gyro gain which differs from Dx6.

As always you are correct.
And once again I overlooked something simple.

Thanks
