RE: Overheating eFlight Brushless and ESC?
That set up will draw 45+ amps, way too much for the e-flite 400. That motor will last if you keep the amp draw around 20. a 4x3 looks real good for direct drive use. Amp draw about 20, static thrust around 20 oz and static propspeed around 100 mph. That should haul your frieght.
