I have been reliably informed the UH-60 Blackhawk Tail Rotor can demand as much as 800 Horsepower.

How much would a 24VDC Electric Motor weigh in order to provide that much output?

What kind of gearing/gearbox/shafting would it require?

What Electric Load would it have to have feeding it....and what would the Generator/Alternator weigh for that?

Where would you place the Electric Motor along the Tail Boom not to have a CG Issue?

Let's carry this a bit further......what size motor would be required to power the CH-47F's Aft Rotor considering it already has two 4700 shp Engines driving the rotor system now.
