This is a motorised helicopter that i built last year.
About this creation
And no unfortunately it doesn't fly. 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 to the pictures:

I can not tell how you made your braking system, but I watched the video, and it seems like it works. This has the basic frame of a helicopter, if you added some details it would look better. 4/5
Thanks. I could create the braking system in MLcad and post some renders of how it works if you want to know. I do plan on making a better version of this some day.
