“Are you volunteering to crawl out on a wing to give the prop a spin in case of failure ?”
Wing? sheesh....you trust the WING to hold the engine? no, the engines should be mounted directly on the fuselage, that’s the only place I would trust it.
And NO I wouldn’t crawl out on a wing, they are made of aluminum and can corrode. I’m for cloth wings, they don’t corrode - and frankly I think it’s a good idea to have two sets of wings, for redundancy, just in case one fails.
