Cole, go for the Lado electric retracts. I put them in my P-47 and they are outstanding. You have no mechanical linkage to deal with and no air tanks, hoses or valves to leak. You just plug the Lados into your receiver and that's it. They seem a little expensive at first but not really much more than a set of quality metal mechanical retracts & servo or a good set or air retracts. Whatever you decide on, get good quality. There's nothing more frustrating than cheap landing gear.
