I would strongly suggest investing in a SAC metal landing gear set I have a set coming in either Tommorow or Friday along with a Quickboost P-61A .50cal set on top of a P-40C cockpit set. Oh and I ordered a Quickboost P-61engine set today from Sprue Bros.
You will definitely need a metal landing gear set for that beast luckily the SAC sets are plug and play especially after major assembly and painting(got that one from the website).
