MOC: Motorised helicopter

Hello all. Wow 20th post already. This time i bring you my motorised helicopter. No it doesn't fly but it does create a noticeable draft. It has a sort of a brake but instead of "braking" it works like a gear box. It interrupts the gear train so the momentum from the blades doesn't keep the motor from turn after it gets turned off. On with the pictures:

And finally a video of it working:

And thats it. Hope you liked it. If you have any questions or comments please feel free to email me or post a comment below. Till next time.
