Question
Dear ZZ

Is it possible to design and manufacture a Lightweight flying helicopter Electronic toy remotely controlled?.

The Helicopter will have a magnet and will be picked up by a powerful magnet inside the remote control and operated by radio signals.

Will the law of gravity not allow for this design?

Thanks
Prashant

Answer
It would not be recommended simple because magnetic materials are so heavy making the law of gravity your enemy.

Some of the light weight new rare-earth, exotic materials are now being used in toys but these materials are expensive and still relatively heavy compared with electronic components.
