Greetings from Finland
I am sure that also there on the other side of pond is many H9 0.60 series planes (Corsair, Hellcat and P-40) just collecting dust because of landing gear failure. That plastic ball joint gets loose if landing is not perfect. I made prototype of how to solve the issue.

Picture 1 problem and solution. Plastic ball joint is the problem and that aluminium plate is solution.
Picture 2 Aluminium plate attached landing gear mechanism.
Picture 3 Landing gear coming to out position. Plastic ball joint turns gear strut. Eventually ball link touches aluminium plate. When wheel causes torque to gear strut during take off or landing, ball link eliminates that torque by leaning against aluminium plate.
Picture 4 same thing from other wiew

I hope that this little tip helps to bring some of those Hangar Queens back to active roster
