    engine mount cups?

    Rusty, the new(er) 912's with the Soft Start ign ain't that bad on start up. The older modles were so bad it wasn't uncommon to shake off a carb or two.

    How do you tune the engine?

    Proper EGT, CHT and Tach is used to determine what if any adjustments are needed. I have a line of props that are less than 400 bucks and ground adjustable. 66" max diameter.

    Rotax 670 build

    Biggest issue with the 670 is the exhaust system. Theirs at least on guy out there claiming 80 - 90 HP and still only turning 6500 RPM. The snowmobile racing crowd is a good power source. Trust but verify. The stock 670 internals are fine.....you'll need a 4 to 1 gearbox.

    Confused by FAA Part 103 - who isn't?

    All's fun and games until the airport mgmt files a formal written complaint with the FAA that you an operational safety hazard. When the airport accepted FAA grant money it also agreed to provide a safe operational area. It's the rouge attitudes that have given Ultralights a bad rap in the...

    Material substitution help

    The VP II uses a similar configuration for its Rudder Post.

    Why the animosity towards ultralights?

    Ultralights are counted as "operations" and at many airports are the majority of monthly operations.
