Hi.
I would like to use exposed prop shafts for my next build, (4mm shafts).
I am thinking about a conventional short shaft tube to just clear the hull bottom but with a full length shaft thru' P brackets,(phosphor bronze bushed), to the props.
How can I prevent the thrust, which will be considerable, from being taken by the couplings/motor prop shafts.
I will be using brushless outrunner motors which I don't think have thrust bearings fitted.
Mike.
