Thanks for the info. The retracts on the plane I got do not clear the bottom wing surface with the wire or wheel in the retract position. I was thinking of taking my Dremel and taking off material under the retract mount but there is very little clearance left like you say under the retract motor or in the fiberglass wheel well. I've uncovered the wings as I'm changing the wing color. The retract strut covers are unless as shipped plus they would be hanging out over 1/8" below the lower wing surface. I may just go nuts and sheet the open bay areas with balsa cover with .75 oz cloth and glass the whole wing. I'm not real keen on a open bay covered wing as we had several AB Skyraiders in Club 40 racing have the covering come loose on the leading edge and blow the wing apart and lose an airplane and that was at 80 mph.
