Default RE: prop saver bands?

Unless you can stop the propeller in the horizontal position just before each landing, your prop is going to pop off, in order to save the weak shaft of the motor.

O-rings are ideal, but you could use regular rubber bands if they give enough to release the prop upon impact and strong enough to keep the prop attached to the shaft at max rpms'.

You could also build some protection for the prop not to touch the ground, made out small piano wire.

Go to your medical supply store and get a few ft. of rubber pipe called Theraband. It's used for stretching exersizes for therapy. Slice it up with scissors or a knife about 1/8 in. long. These rubber bands will work much better than the neoprene rubber O rings.
