Physics/Lightweight flying helicopter Electronic toy design.


Dear Prof Steve

Is it possible to design and construct a Lightweight flying helicopter Electronic toy having a magnet and pulled up by a powerful magnet Embedded in the remote control and then operated with radio signals technology?


Hello Prashant,

Of course it would be possible. But I can't guess what the benefit would be which could offset the difficulty I anticipate. I am certain that you know these characteristics of magnets: Magnets that are almost impossible to separate when they are in contact, have very little attraction when separated by 300 mm.

I hope this helps,

I would be delighted to help with questions up through the first year of college Physics. Particularly Electricity, Electronics and Newtonian Mechanics (motion, acceleration etc.). I decline questions on relativity and Atomic Physics. I also could discuss the Space Shuttle and space flight in general.


I have a BS in Physics and an MS in Electrical Engineering. I am retired now. My professional career was in Electrical Engineering with considerable time spent working with accelerometers, gyroscopes and flight dynamics (Physics related topics) while working on the Space Shuttle. I gave formal classroom lessons to technical co-workers periodically over a several year period.
