Hi,
for some equations on power required, etc see the attached file. Is it referenced for human-powered helicopters but has lots of good information and equations.
For small helicopter information, try scaling the Yamaha RMAX: it uses a liquid-cooled, two-stroke, 246cc engine rated at 21hp and has a blade radius of 3.4m (~12 feet):
Main rotor diameter:
:
3,115 mm
Tail rotor diameter
:
545 mm
Overall length
:
3,630 mm (including rotor)
Overall width
:
2000 mm
Overall height
:
1,220 mm
Weight
:
approx. 93 kg
Two blades will be less efficient (smaller radius, turn faster) but might help you reduce your footprint.
