Just thought I would tip the forum to this:

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 :)

My question is how much does a Mazda RX7 12-A engine weigh and how many rotors does it have?

Thanks,

My guess is within ten or twenty pounds less than a 13B. Two rotors just
like a 13B only a bit narrower. No replacement for displacement.

BTW from the looks of the stock air cleaner is has a stock four barrel carb
which is useless for aircraft use but valuable in the after market.
