A flying toy has a propeller rotated by the first motor mounted on the body. A propeller holder mounts the propeller. An end cap is located to the front of the propeller holder, and there is a snap joint between the holder and the end cap. The end cap is removable by disengagement of holder and end cap at the snap joint, and the propeller is releasable from the holder by a human hand and without a tool. When the toy crashes, the propeller is forced relatively free from the drive force rotating the holder and back towards the body and is trapped against separation from the toy.
