Hello to all.
I have a new OS 120 Surpass 3 with about 1/2 gallon of fuel through it. Fuel is 18% Klotz Super Techniplate and 10% nitro and I have OS type F glow plug.
I can get 2200 rpm idle and 8800 rpm full throttle with a Graupner 15-8 prop. Does this rpm are OK or should it get some more? (the transition is excelent)

Thanks in advance.
