tolla; I know alot of people who tried that servo and only one of them are still going and consiquently it is on 5v but it still heats up more then it did when first used. I have read all the hype about it being over voltaged being the culprit for it burning out but it burns out on 5v aswell. I have come to the conclusion it is too small for the high stress of 3d flight. plus i run a 2200mah battery that weighs in at 170grams so i need something with alittle weight on it back there.
