The gear box is dangerous as the stock shaft diameter is not up to the

gyro

bending loads loads imposed by a prop. There is no way to put a large

enough shaft

in the stock gear box. Also the gears themselves are marginal for

continuos

high HP use. Trash the gear box.

The test stand alone is worth $500 if you need one. I am thinking
of bidding. Last thing I need in the hangar however is another test stand

:)

The engine is worth probably about $1000. 12A engines are not very costly
on the used market. Only the road racers use them and that is because the
SCCA forces them to use them :)

Dale, apart from Paul's comments, the housing is a manual (all in one bell
and gearbox housing ) I don't know if the full housing has been used or it's
a cut and shut. If it has been cut and welded I would be concerned as
injection casting has a lot of silicone to help with flow of molten
aluminium in thin castings. The silicone doesn't allow good penetration for
welding.

The stresses on the housing is also different on a car to what will be seen
on an aircraft, there's no ribbing to accommodate those forces.

The Planetary from the Mazda - although similar to the Ford is much
smaller/lighter.
Is there a damper and what is it !?

The questions go on and on - the motor and the frame seem OK. It would be a
good test rig and something I'm looking for, but it's too far away for me.
