RE: 1/7 Top Flite Spitfire or P47, which retracts
I have the ARF TF P-47 and I used Lado's. Sure they are a little more expensive than mechanical retracts but they have been absolutely flawless so far. No linkage to set up, no leaking air lines, no problems. A good set of pneumatic retracts aren't cheap either so the Lados are well worth it to me.
