Hi,

My friend was flying his large composite EXTRA with a big AXI and 10S lipo and hyperion 90A speed controller, everything was going just fine until about 3 minutes into the flight turning towards at 1/2 throttle it froze with throttle on and sprialled into the ground, control was lost but the power stayted on.

The model was beyond, close examination shows that all linkages were ok, the battery lead was ripped out of the receiver (the plug in but the wires pulled out), power was still in the receive pack.

The RX was a JR 7 chanel SPCM with 3 flights under its belt, everything in the plane was brand new.

My question is what could have happened for the plane to freeze, with throttle still on, failsafe was set to cut the throttle, there were no glitches it just froze and spiralled in ?

Thanks for any comments you have

Are you running a seperate BEC. If not, I'd wonder if your BEC didn't overheat and by the time you tested everything it could have cooled down and allowed the servos to respond. Just a thought.

There was no BEC just a brand new receiver pack 2400mAh Nimh ?
