Prop is 2 bladed 20X8 Hawk (wooden). Muffler is the black box muffler by MVVS.

Tempreture was 12c , sea level. The engine is new, ran the 4 tanks on 1/3 or little less of throttle range. Did a full throttle just to check the RPM.

What is the Max. rpm for this engine, what can u get of it with box muffler.

I ordered the Bisson inverted for this engine, waiting for it to get here. wht would i expect the range of RPM with bisson muffler?


Thanks
