So why not make a seperate door for the wind-generator?
Open it drop the wind mill and close it, to reduce drag.
If you loose power and battery (..worst case - sh** never happens alone...),
you don't want all the drag you describe below, until you are ready to
land....

Subject: [FlyRotary] Thoughts on an Alternate Alternator
It occurred to me that for those among us with retractable gear, a
wind-powered alternator might be an interesting approach to a back-up
power
source.
You could rig the standard wind-powered generator/alternator (like
Ward-Aero) to the gear leg of a retractable landing gear. When you deploy
the gear, the generator is put in the wind and produces power. When you
retract the gear, the generator is tucked away and is not producing drag.
The back-up generator would be on-line during the most critical portions
of the flight, during take-off and landing. You could deploy the generator
during flight by simply dropping the gear if there were a problem with the
primary generator.
Alternatively, if you are considering some sort of custom air brake,
perhaps you could incorporate a wind generator in it.
Hmm, with the increasing number of all-electric airplanes out there, a
combo air brake back-up alternator might sell pretty well.
Just a thought,
Bill Dube'
