I have a P120SE in a Flash, the airframe is new but the turbine was in a previous model, it ran perfect for the first three flights, then I had a wet start as I forgot to open the fuel valve until half way through the start up, then a nice flame out the back, all shutdown ok and checked and seemed ok.

But on the next run up the throttling was not perfect like before, there were a couple of momentry hesitaions as I opened up the throttle, all obvious things were checked, fittings etc.

This was put down to the pump needing to remap to the ECU as the pump voltage would have gone high during the problem start up.

Anyway changed the throttle setting to normal instead of fast in flew it a couple more times all seemed ok although not running as before.

Then this week went flying and after sitting idling for about a min on runway it flamed out just as throttle was being opened up, restarted and did again, then run in pits and all seemed ok, then flew the model and seemed ok,

So today I swapped the fuel pump just to see if that was the problem and it still did it, changing the engine throttle response to slow seems to help but there must be something wrong somewhere ?

Any ideas before I send it off to Jetcat.

Cheers

On a full size it sounds like an ECU problem.

But, I'll probably be bashed for saying that.
