RE: Crow set-up.
Yup- just remember "spoilers= Throttle"
Thats really the only difference- there are more mixes for 4-servo wings in the sailplane mode. I have a 388X- the fore-runner of the 783, and I used sailplane for my Magic- worked fine. Plus if there is anything silly you want to do there are like five free- mixes in the sailplane section. No assignable switches though... Just on, off, and switched.
GL in your programming.
