I have a firebird xl electric plane and I need to take the prop off but I can't figure out how to do it!! There is no nut like a standard prop. The only way I can see to do it is to just pull, but it isn't budging. Can someone help me?

pull... it is only held on by friction. (only take it off if you are replacing the prop or engine, if stays on fairly well by itself, but you may have to CA it on if you remove it a couple of times

THX. I am changing the propeller to a new fuselage. The old one got beat up in a failed corkscrew dive.
