Yeah I hear you. I made the ailerons twice the surface area from scale- I assume that will be enough.
First- Elevator and rudder servo placement. My life would be a thousand times easier if I just placed the servos under the horizontal stabs and on the side of the rudder- much like the Windrider 737. Originally I was going to place them internally and run long push rods. The difficulty with this is getting the two elevators symmetric since I don't want to be punching tons of holes in the fuse. See pictures. I do have tons of spackle though.
Second- Spoilers- I can either keep them scale for looks or increase the size per the pictures and have them overhang the flaps about 5mm The nice thing about this is that I will be able to round the upper surface of the flap which will improve appearance when deployed. Not sure if this is helpful or just plain stupid.
