After finally getting every piece on my plane to work, another piece decided to be a problem. Great.
My problem is pretty much already summed up in the title, my prop keeps flying off my motor, and I want to stop it from doing that because no prop pretty much means you crash.
Here is a picture of the motor pod and prop unattached from each other.
Here is a picture of the prop hardware that goes over the motor.
Sorry if the pics aren't working, I don't use them a lot and haven't quite figured out the syntax and stuff. Any suggestions on how to keep the prop on during flight?
