Took Erichs lead and replaced my heavy gearbox wearing warpdrive on my 912S with
the E-prop glorieus 8lb all carbon hydraulic (engine oil) constant speed prop.
Manno! What a different aircraft it is now. Takes off and climbs with all 90hp
now like crazy, and is able to do 145nkots at max continuous (7gal/hr) down low.
Previous relaxing cruise settings give about a 5kn increase for the same fuel
flow too. And the new gearbox internals appreciate the effortless instant
start and stop without the previous typical rotax dog-clank. Much smoother
as well. Terrific performance and ~1lb lighter than the warpdrive and classic
spinner.
Minor nits: controller display goes blank intermittently, and the blades have
more play in the hub than id like (Erich reports no play on his, factory says
its normal). Factory is quite supportive tho.
Best transformative investment to-date.
Cheers,
PeteZ
