Scale Aircraft Conversions is a name well known for their replacement white metal landing gear for many different scales and kits. This set provides replacement for the Modelsvit 1/48 XP-55. Besides the landing gear you are also given a white metal nosewheel gear bay roof which will no doubt aide in preventing the model from tail sitting or at least reduce the amount of added nose weight required.
These are drop fit replacements for the kit plastic landing gear and are also stronger.
I have used many of these sets on my tricycle landing gear builds. The extra strength of these is extremely helpful especially when a large amount of nose weight is required. They are always well molded and easy to use. CA glue is required, and I have used every type of model paint from acrylics to lacquer with no problems.
