Simjet 3000 low rpm
My Simjet 3000 has run faultlessly for a couple of years. I recently flew the same model twice in one day. The first flight seemed to fly as per every other flight I have had with this model/engine combination, but the last flight the engine seemed down on power. Looking at the ECU readings, the MAX RPM is set at 122000rpm but the engine is achieving from 118000 - 112000rpm. Any thoughts as to what is causing this?
