I have built 4 Magicians, all with moveable flaps. I have never built one with fixed flaps so I can't really tell you anything about that one. On my flapped ones, I use 1 to 1 ratio flap to elevator. On mine, about 20 degrees has been plenty on the elevator. I do move the balance point back to about 3/4" ahead of the spar because of the flaps. If you build the fixed flapped version, I would move the balance point forward to what the plans show. It should fly well either way.

Thanks Richard; I was looking at your picture of yours, and I was amazed as it looked exactly like mine at that stage. Cloth hinges and all. It is a neat plane and you are doing a superb job. Makes me want to go build another.
