I'm a happy owner of a Mammoth for 6 months only, the engine is 7 hours running now and powered a F16 1/6. Take off weight 23kg.
the engine is gaz start and I know that jet central is working on the kero start version.
During winter start was slow even after removing the gaz restrictor between the gaz valve and the engine.(temperatures below 10°C).
The acceleration is really good as my jet munts 160.
the noise is really much more important than a class 160 and the power too.
fuel comsuption is equivalent of a P200, I can fly 6min with 4,6L on board, with 1,5L remaining after landing, and 9'30'' of total running time from start up and cut off.
No flame out for the moment either in normal and inverted flight.
Before the Mammoth the F16 was powered by a Merlin 160 and Take off weight wax 19kg.Now with 23kg(engine weight difference+additional fuel+ under wings loads), the aircraft seems less heavy in flight and max speed increased seriously.
The engine max RPM is 104000 Rpm compare to a P200 112000Rpm.
That's my first Jet central but it seems to be a good engine.
let see for the next hours...
