New to VTOL Tilt-Rotor: ZOHD Altus

ArduPlane VTOL Plane
1

Decided to try Ardupilot running 4.6.3 plane on the ZOHD Altus VTOL. Pulling my hair out just getting the aircraft setup in manual mode. Right now the V-Tail is the issue, either the yaw or the pitch are backwards and cant get the two to work in sync correctly. Would appreciate and help from you fine people. :smiley:

Including my param file, please be kind. Point me in the right direction. Yes I did RTFM :exploding_head:
ZOHD Altus VTOL with Speedybee F405 Wing Mini, and ELRS RX with Radiomaster TX16S, using ArduDeck V0.0.30 on Apple Mac Mini.

IIRC fixing V-Tail configuration is described on the wiki for VTails.

Page linked below. Sounds like the fix may be to swap left/right output functions (79 and 80). Don’t get too hung up on the “left” and “right” words, in this case.

I’ll read it and see if I can get myself straight. :grin:

OK off i go to try and digest it all !

After many hours reading docs and experimenting with settings, I finally have the vtail figured out! Had my brain twisted in knots for quite some time.

To make it easier on myself I simplified:

SERVO1_FUNCTION 4 aileron
SERVO2_FUNCTION 79 left V-tail
SERVO3_FUNCTION
SERVO4_FUNCTION 80 right V-tail

Thanks all!
