I have put together the Super Airliner by E-Flite and flown several times. Problem is, the darn ESC units keep going out on me and I don't know why. I have had two burn out on me now... lucky I wasn't flying either time... just hooking up the connections to fly and then could smell them burn and then the motor won't run smooth. Is it possible that they are just getting too hot from flying over time? I have the 400BL motors, 25amp pro ESC (E-Flite) running from 2 2200 lipo's. I'm just wondering if the cause is from the ESC units not getting enough air flow over them and this is causing them to only get about eight flights on them before one seems to wear down. I hardley fly more than 75% throttle too. Why do I keep frying up the ESC units?
