Hi,
> Are you sure of your MP gauge and tachometer calibration ?
I don't know anything about 914s but I do know that the standard Rotax
analog tachos are notoriously inaccurate. They often misread by more
than 400 RPM.
A person I know (who shall remain nameless) who has a 912S discovered
that their Rotax tacho was under-reading by 600RPM! Says something
about the durability of Rotax engines!!!
Blatant plug: If you buy a Smart Avionics constant speed controller
(www.smartavionics.com), you get an accurate digital tacho with
percentage power display that will work just dandy with a 914. It
takes the same amount of panel space as the Rotax bogo-tachometer.
Regards,
Mark
