Patent ID: 8430709

Claim:
A flying toy comprising: a body, a first propulsion unit, having a first motor and a first propeller rotated by the first motor mounted on the body, a propeller holder for mounting the propeller including an end cap for location in front of the propeller holder, a snap joint between the holder and the end cap, the end cap being removable by disengagement of the holder and the end cap at the snap joint, and the propeller being releasable from the holder by a human hand and without a tool, and the holder including a drive shaft for engagement with the motor, a stub for mounting the propeller, the propeller having a bore for accommodation on the stub, the stub and bore having an interface whereby the propeller is mountable for normal operation to be rotatable by the drive shaft in an essentially right angular transverse plane with respect to the drive shaft, and wherein with the drive shaft rotating in a normal drive mode, and with a removal of the propeller towards the body, such removal effectively disengages the propeller from the drive shaft whereby the drive shaft rotates in the normal drive mode and the propeller is removed from the rotating drive action and is trapped at least in part between the body and the stub.
