Looks like a kit built Kadet Senior (also based on your stated wingspan) You will have to build mounting plates for the aileron servos.
You will need a .46 to .61, 2 stroke glow or .63 to .82 4 stroke glow. I have flown both of my Kadet Seniors (1 ARF and 1 from a kit) with .46 2 strokes with fantastic results.
The engines you have are too large for that plane.
You will probably have to look around a bit to find a compatable receiver for that radio.
