Hi Dutch,
I too am in the middle of a Guillows build of a Thomas Morse Scout. Its going to be old school .020 gas and control line.
Your kit is a pretty good one, except Guillows balsa is not the best and will need to be replaced in some areas with a better grade to take the stress of the RC conversion.
Google your kit name with "RC Conversion". There are some really good tutorials on the internet on how poeple have made this Corsair kit work for electric RC. There are a lot of motor and ESC choices to make, so many, it makes my head spin.
The plane will be very light, so I doubt you will need to make the flaps. I've build several Corsairs for RC and those flaps are a bugger to make.
The amount of channels you may need is 6. Aileron, Elevator, Rudder, Speed/Throttle, Retracts, and then a sixth if you plan to have a release for a bomb or rockets.
I look forward to seeing you project.
Scott
