Hi.
My Alpi Pioneer 300 is running on a Rotax 912 ULS. I have a MGL Explorer Lite EFIS operating through an RDAC XF and a Flybox prop governor. The wobbly prop is an electrically driven hydraulic system call Idrovario (also Italian). Over the last two flights, the EFIS RPM gauge and the Flybox governor are about 700-800 RPM out, with the EFIS reading lower than the governor. Also, it is clear the prop is overloading the engine, creating a variable shuddering effect.
Has anyone else experience of this, and any suggested fixes please?
