Just noticed my typo in the subject - coupling
Hi, Having been supplied with the plans for the Perkasa a few months ago by Doug and now having a bit of time on my hands, I have just received my brushless outrunner motor. My question is do i use the plain motor shaft that comes out of one end of the motor or what I guess is the alloy device for mounting a prop on an aircraft? The latter fastens on the opposite end of the motor to the shaft, mounts on the outrunning element. Actual mounting of the motor will vary depending on the answer. Photo attached showing the plain shaft and alloy thingy.
My follow on question is what are recommendations for couplings these day? I have read the blog from 3 years ago but as things move i wondered what the current suggestions are? And possible suppliers in the UK.
The plain motor shaft is 4mm dia
The alloy thingy is 6mm dia (the unthreaded portion)
My propshaft is 4mm dia (the unthreaded portion)
Thanks for any advice offered.
