[TC15] Propeller Launcher

[Lucullus]

Hello everyone.

My entry for the Technic Contest 15 is based on the simple idea, that all Lego motors have a too bad power/weight ratio to be used to power a flying object, as long as they stay a part of this object. Therefore I used a Pullback engine to power a simple propeller to make it actual fly. As this alone would be a little too simple I decided to build an aiming/launching mechanism arround the basic concept.

The functions are:

-tensioning the motor by a worm drive

-blocking/releasing the motor

-rotating and tilting the launcher

Hehe, I loved doing this when I was young with little motors and small fans. It actually flies quite far, I’m impressed!
