hi Doug,
just logged on for info on just the same problem. i have a Hacker A40-10S and an airboss-80, i have found that the amps are spiking very quickely and the speed controller is kicking out from too many amps, it makes a terriable noise when this happens. Once i hooked up the watt/amp meter it was easy to see and i thought dialing back the throttle travel to keep the amps under control was the way to go but that means dialing the travel back to 37%, i think this is strange but was told to go ahead and run it for now. So, four flights later i have nothing at all working i have two ESCs and changed over and i still get nothing. Ido see the bind light blink on the rec. when flipping the switch. i have emailed the hobbyshop and have not heard back from them
