Launcher
The
Stunt launcher is a stunt plane launcher that straps on to the user's
arm. Before launching the foam planes the user can adjust the flaps
on the plane to control its flight course after launch. The principle
of this device is based on the spring Mechanism inside the plane. When
it is pushed against the wrist-launching device, the spring is compressed
and the trigger device on the launch pad keeps the plane from launching.
When released the spring will push back and the plane will launch into
the air. Construction
Cost: Components include plastics and springs. Construction cost should
be around 10 USD. Durability
and Safety: The hard plastics are durable and shatterproof. It is lightweight
and it does not contain sharp edges. Suitable for children ages 14 and
up. |
