Have had issues posting the past week, but as it turns out others have said what I was going to say anyway so no great loss. 🤣
The Drive Article is probably the most balanced read I’ve seen about all the discussion on this topic. If you want to read other interesting things related to V-280 I can suggest searching for US patent 10,570,931 B2 where Bell describes the tilting gearbox/prop rotor in great detail, with drawings of the drivetrain.
I found another patent for the possible Hydraulic system as well but I forgot to save it. Will post later when I find it.
