Hi folks,
I am writing you as I need some guidance on where my speed is missing....
Summary:
The plane:
My performance (all measured with Dynon HDX):
The performance of a build-alike RV9a, same config:
Here´s a link of a 2.5h flight showing the same data:

I am writing you as I need some guidance on where my speed is missing....
Summary:
- I believe to be at least 10-15kt short of TAS at cruise. Question is aerodynamics vs. engine performance... I can´t think of aerodynamics...
- Would be great if you can let me know where to look for some more knots
The plane:
- RV9A / (Y)O-320-D2G (ordered from Vans), carburated, fixed pitch Sensenich 70CM7S9-0-79, dual mag ignition, all flaps and controls even and on surface, gear boots installed
My performance (all measured with Dynon HDX):
- 5000ft, 77%, 2500RPM throttle wide open, lean, 35L/h (9.2USgls), 144KTAS (166TAS mph)
- at take-off on MSL I am reading 2200RPM
The performance of a build-alike RV9a, same config:
- 6000ft, 77%, 2500RPM, 39L/h, 161KTAS (186TAS mph)
- 6000ft, 63%, 2300RPM, 34L/h, 145KTAS (167TAS mph)
