I just received a set of rotating retracts with longer struts for my TF P-40E Gold Edition from Darrell, and the retracts turned out superb as expected. These retracts would also fit my Hellcat with 4" wheels. Darrell added more meat to the axle end of each strut, which is a plus. Unfortunately, these rotating retracts do not have any toe in, so the next step for Darrell would be to incorporate 1.5° or 2° of toe in per axle to improve ground tracking and handling. It's too late for me, but I know Darrell would make this happen for future sets. Without toe in, on landing, the wheels and axles would flex back, creating a toe out condition that would increase the tendency for the plane to nose over.
