Stay tuned. I have a SH-60b Seahawk 1:35 on the shelf that I'm starting in a month or so. Apparently, one of the rotor hub parts was produced backwards. I'm going to attempt to 3D print a correct one. If it works, I will make it available to other builders. There is a scratch build fix that requires a lot of cutting and gluing, but a newly formed part will be more secure.
