The way this airplane floats in you will not need flaps and the ailerons really are not that big so I do not think that they would be that effective for flaps anyway.
If you end up doing the dual aileron mod and your radio is capable of doing flap programing you can use the radio and the two servos to move them into the flap position.
As I said they will not be need this airplane is a dream to land as it floats in.
I loved mine until the experation date hit which was after only a few flights.
Went thru a number of airplanes that year should have seen my wifes eyes roll when a new package was left on the front door.

Ed,
I think I can make that mod without any problem, I hope. I was also thinking of cutting the aileron and using the center servo hole to make flaps.
I've seen it done that way on a Spitfire and a Chipmunk that I had.
