I had flown my super Airliner twice before it lost all power midflight and crash without control. My findings tell me it was that the reccommended E-flite 20 amp ESCs were overloaded, got to hot and shutdown temporarily causing the out of control condition. I used all the reccomended e-flite motors, ESCs, servos, batteries, except for my RX and TX. I have been getting the parts needed to build a new one, but I am doubtful if I will use the E-flite 20 amp ESCs again because of the failure. If you look at the specs on the motors versus the ESCs it appears that the ESCs dont support the burst current or continous for that matter and require a UBEC for it to work correctly. When I called E-flite about the crash they said I needed an on-board RX battery pack and should have disabled the BEC on the ESCs so the RX battery would power the servos. What ESCs are you guys using out there? Anyone else have random power out crashes due to the E-flite ESC? How are you providing extra cooling to the ESCs? I dont think the manuals instructions that call for the ESCs to be covered by the tape allow proper cooling. I know some folks on the wattflyer board that had identical crashes to mine. Thanks
