What prop are you using?
xKmotx 3 years ago
I believe when this was filmed I was running a 16 x 8 Xoar "Sword" in white. They're amazing props if you haven't already heard of them. Here's an adderss for them: (replace DOT's)chiefaircraftDOTcom/rcmsec/Models/Accessories/Props/XOARPropsDOThtml
Also I was only running 15% nitro and that is NOT enough! It needs 25-30% nitro or it knocks and robs power. This video doesn't reflect the engine's full potential.

O.S. FS-120S-E Surpass 4-Stroke w/o Pump = 1.9 hp @ 11,000 rpm
O.S. FS-120S II Surpass w/Pump = 2.1 hp @ 12,000 rpm
O.S. FS-120S III Surpass 4-Stroke w/Pump = 2.1 hp @ 12,000 rpm
O.S. FS-120S-SP Surpass Supercharged = 2.5 hp @ 10,000 rpm
