Okay so just to explain my problem. I have a central shaft that has two belt drives connected to it. Each belt goes to a propeller on either side of the drone. I need to connect the shaft that is being spun by the belt to a propeller. I'm using the APC 13x6.5 props. The parts I need The shaft that is being driven by the belt, and a means to connect that shaft to the prop. I was on the motionrc website and it seems to me that it would be much more difficult to use one of type a,b, or c adapters, so I thought about a collet. Now if each prop is making 6lb of thrust, I want to make sure that the gripping force of the collet is sufficiently high enough. I was wondering how I could go about this. I understand I need to calculate the strain, as a result of the applied force used to tighten the collet, but for that, I would need deflection, so I'm stuck. Can I get some steps and explanations on how to calculate this?
By the way, the thrust from each prop is around 6lbf.
