Yes, that is my plan, to have the spoiler/flap combination. I'm not planning to use the original linkage, however. My plan is to have four servos in the wing, and the retract servo at the centerline. I'm just now trying to figure out the best location for the wing servos.

The retracts that I will use are the ones I was able to pick up at the LHS. They are Hobbico retracts. I hope they will be ok, as I have passed the point of no return on that decision/
