Today I did an experiment.
The new RV-8 has 80 hours on it, and I have had opportunity to do all the tweaks. Part of this included setting the SkyView ADHARS so the HSI is on the horizon for level flight, and this setting has been confirmed over several long cross country runs. This was done solo with 25 pounds of balllast in the rear baggage compartment.
Today I jacked up the tail to compare HSI in level fight to the canopy rails (what i always assumed as “baseline level”). The result was with the plane, as measured on the canopy rails, is nose up by 1.4 degrees in level flight.
So my questions to all you AEs out there:
- Is this what others have found - as in typical for RV-8s?
- Is this indication the thrust line is not quite high enough?
- Anyone experiment with changing the engine thrust angle?
