Helicopter experiment

Hi Guys.

I'm new to arduino, and discovering this great product.
However, i have seen many 'helicopters' on youtube...

What motors do you need for this things?

Shound DC Motor be enough?

Hopefully you can inform me!

Thanks!

The most critical design parameter for a helicopter is its weight.
Without knowing that , its impossible to know what motors will be needed.

And how do I find the balance? What is te basic, and how to calculate if it's enough?

Many thanks!

You need about 1 watt of power to lift 10 grams.

You might try playing around with the calculators at http://www.ecalc.ch/
