Gents:
I am building a Unionville Otter, 72" span. I went with separate flaps and ailerons just to have fun with them. I am putting in separate outboard servos in the wing for the ailerons and servo(s) in the centre for the flaps. Given the span of the wing and the size of the flaps, about 1 ½" X 12", would I need one or two servos? I would be using standard Airtronics servos. I think the max size of the engine would be a 40 or 45, depending on the weight.
Many thanks for any advice.
