Hi again, Brenner.
I found that section, and WOW ... there is no question in my mind that you made quite an improvement in bearing and gear life with the improvement in stiffness of the system.
Grabbing the tail-shaft with a bearing does wonders too, I'll bet.
In CL Stunt, where guys were mangling bearings on rear-mounted outrunners in maybe 100 flights, turning them around and mounting at the front made almost everybody's problems go away.
The problems that were left, almost all of which signaled their presence with funny noises in the 1/4 second long 1/4 loops, were due to flexibility and resonances in the fuselage.
The tail-shaft bearing killed those, though most guys don't need it now that we understand how to build stiff noses and use 0.093" G-10 for the motor mount former rather than mere plywood.
again, Bravo
Dean
