Hi John,
actually I really donīt know.
All meassured flights with number two up to 455 km/h were done with 120.000 RPM.
The flight with 470 km/h and 481km/h was done with 123.000 RPM and turned clamps.
The extra speed probably had two reasons.
The higher RPM and the changed clamps.
And the colours are very important. Again in my opinon this is the best combination of colours for high distances flights.
It doesnīt make sense if you paint a plane in camouflage and try to fly far away.
