Wind was my first thought as well. For quad-copters the simple fact is the lack of collective pitch does massively affect the maneuverability in adverse conditions. You need a high volume of airflow over the blades to compensate and fixed pitch there is not much you can do to increase airflow without climbing rapidly. (although whether you could do it with an octocopter with four of the blades pulling down and four pushing up to counteract the climb?) There are plenty of model sized helicopters (even some microhelis with 8" blades can handle 15mph with a skilled pilot) that handle wind very well - they just need a high head speed.

iirc the most recorded for an electric eel was about 600volts and a bit over 1 amp. Wikipedia claims 500v, 1amp produced through a series of cells each producing 0.15v. Of course this discharge is pretty short, each pulse being incredibly quick. Not sure on electric eels, but electric catfish can only discharge once every hour or so as it takes time for them to charge up again.
