Default Kyosho GeeBee Engine/prop?

O.S. .91 FX two stroke with a 14x6 APC prop at a little over 100 mph.
According to ThrustHP, there is no way an APC 14x6 spinning at 12,000 rpm can get you over 100 mph. If what you said is true, then a YS 110 spinning an APC 15x10 at 9500 rpm can get you over 120 mph.
