Tamiya’s Wildcat has been around for a while and it is an excellent kit. Scale Aircraft Conversion has produced a set of metal landing gear to use on the kit. The set includes all the gear parts including the portions up inside the nose. A new tail wheel is also included. The metal parts are well made and are drop in replacements for the kits parts, but are made of metal. The metal is stiff but retains its malleability. Some cleanup will be needed to free it from the molding sprues and I recommend a razor saw for this work.
Several modelers have asked me “why metal gear”? I agree, that this kit is not particularly heavy and my answer is twofold. First, have you ever lost a part? I have and while you can get the parts for most kits, getting these sturdier parts is much easier and it may be cheaper that the alternative of buying an entire sprue to get a part or two.
