Guys I almost have my P-51 done but have a question. The retracts that came with the ARF (CMP) dont lock in place totally. The retracts seem to be a bit lose when extended and retracted. Its not by much maybe an inch or two. Is there anything I can do to remedy this or is this not a big deal? It seems like a big thing to me. They lock in place but there is a little freedom each way( closed and open). Please help!
