You can go here to read about what’s available.
You can either use one of the following airframes:
Generic quad delta VTOL

SYS_AUTOSTART = 13006
Specific Outputs:
MAIN1: motor 1
MAIN2: motor 2
MAIN3: motor 3
MAIN4: motor 4

AUX3: Motor
Vertical Technologies DeltaQuad

MAIN1: motor 1
MAIN2: motor 2
MAIN3: motor 3
MAIN4: motor 4

You’ll need to search what other folks with the same airframe have used for quad and pusher motors. You can check out what Vertical Technologies used on theirs.
I converted a similar airframe with the RVJet where I used the Generic Quad Delta airframe as a starting point then tweaked it from there.
Good luck.
