RE: Electrically Powered Helicopters

["Rodney Benn" <rodneyb@uec.co.za>]

Hi, Actually I do not know, and not many people can tell me how much power the 
rotors of a hello' need when out of ground effect and not in the hover.

ie. when going forward at say 50MPH ?

Are there any good mechanical engineers out there who would like todo some qwik 
sums?

ALso, does anyone know the formula for working out the thrust produced by a 
spinning helicoptor set of 2 rotor blades ? Spinning at 0-1000 rpm range.
