Here in Central New York we have the cursed humidity you speak of. My brother-in-law moved up here from North Carolina and he says every summer that it's way worse here. Not to mention the winter... It's like the worst of both worlds! Ohh and it's windy or raining most says to top it off. To tell you the truth, when I run my 3s Lipo, I'd be happy with like 5 hours of use on those motors. They're only designed to handle between 3 and 6 volts, so 11 really pushes them hard. Honestly I never expect either motor to last long on the heli. I do want to get a dual tail motor setup though. Ohh, I am thinking of trying another motor I have next time the main goes, I started a thread about it. If I actually do it and it works out well I'll let you guy know what motor and where to get it. I have high hopes.
