Abstract
A propeller-driven toy flying vehicle set which includes a hand-held launcher and a propeller-driven toy flying vehicle detachably mounted on the handle. The toy flying vehicle, which may be in the form of an airplane, has a body with wings and a propeller which is substantially oversized with respect to the body and wings of a conventional propeller-driven airplane. A gear-driven mechanism is included within the hand-held launcher which is actuated by pulling a member, such as a string, to impart rotation to the vehicle propeller while the toy vehicle is retentively held on the hand-held launcher. The gear train includes multiplier means, in the form of step-up gears, to increase the speed of rotation imparted to the propeller through the pulling of the string. After the string has been pulled sufficiently at least such that the speed of rotation of a drive shaft in the mechanism is less than the speed of rotation to the propeller, a coupling means detaches the toy vehicle from the launcher permitting the toy flying vehicle to 'take-off' into flight.
