I'm all for clean sheet designs building on old knowledge so Im not trying to find faults. I just want to learn more about the design.
Looking at the patent application, I saw something on the diagram Fig.7a.
The center push tube splits into two paths and wraps around the engine input drive shaft before being connected to the servo.
Will there be some protection provided to the push tubes should the drive shaft split and flail about?
How is the fuselage held to the transmission and how are misalignments and expansion dealt with between the engine and transmission?
