I have tried two types of prop adapters on my Sportster and don't have a lot of confidence in either method.
I haven't flown the plane yet but I am almost afraid to.
Which method is best? The collet or the set screw?
It seems that, since the set screw is tightening down on a smooth shaft, there isn't really that much to grab on to.
The set screw adapter came loose tonight when I accidently reversed the prop direction on my TX.
Prop came flying off and I started thinking that might happen when I am flying.
I was wondering if I put a groove in the motor shaft where the set screws hit, wouldn't that give it a better chance of staying on?
Do you have to really, really tighten down the collet to get it to hold on to the shaft?
It also came off when I was testing the motor.
I can't be the only one that has a problem with these things (or can I?).
I'm new at this and need some advice from all you experts out there.
