Hobbypartz.com has great prices and great motors. I think. But for some reason I seem to be having some very bad luck frying motors lately.
I've been running one of their 450TH motors rated for 230 watts (http://www.hobbypartz.com/45oubrmo6.html) at exactly 230 watts, and haven't had much issue with very short bursts at the 230 figure of 40 seconds or less for takeoffs.
BUT-- For the first time I flew full throttle the entire flight, mostly due to winds, and the motor and controller both fried. That's 20 amps through at 25 amp controller, 3 cell lipo, which is roughly 230 watts. This outrunner motor is out in the open air, so it shouldn't be overheating.
I know the rule is probably to run way under the motor's rating, but what do you guys think? Is it unreasonable to expect a 230 watt motor should run 230 watts for at least a few minutes? This is the 3rd motor that has done this to me, and I am starting to think that I should be running 80% of maximum as a rule and see if that gets me any better luck.
One possibility though. I have to limit max throttle to 75% to keep the current at the maximum of 20 amps. Could running a controller in this way cause problems?
Thanks for any ideas!
