Well, you're not going to like my answer, but you asked. I'd say 10% chance of even surviving the first flight (with an experienced RC pilot) would be on the high side.

I think it's a noble goal, and you'll learn a lot by building it, but it's on the very edge of possibility in my opinion. There have been a few successful conversions of Guillows kits to RC. They are usually predicated on keeping the aircraft as light as physically possible by replacing Guillows' notoriously hard, heavy balsa with contest grade, then using the very latest in light weight RC equipment, AND by limiting the plane to three channels, throttle, elevator and either rudder or ailerons.

By adding retracts, a lighting system and a camera, I doubt that the plane will be capable of flight.

Try this. Figure out what your wing loading will be by getting the wing area in square feet and the weight in ounces. (You want the loading in ounces per square foot.) For a plane that small, you don't want the wing loading to be much over 15 to 18 ounces per square foot. I'm guessing your's will come in closer to 30 (or more).

You might get it to fly by skipping the retracts (maybe landing gear all together), skipping the lights and camera, keeping it to three channels, and using the absolute lightest RC gear around. I'd suggest something like a GWS RS-4 receiver, and their Pico servos.

Using a couple of geared electric speed 400 motors will also let you use a small Lithium pack for power and radio, and eliminate one servo by using a speed control for throttle.

Just my thoughts.
