Hello Paul & group,

I promised to make a 45 min aircraft rotary prensentation for the winter
meeting of our local EAA equivalent. I have about six weeks to put it
together.

I thought to address this from the viewpoint of builder, thus the
salient points could be:

- How much there is 'em? Flying and being built? (Tracy's PSRU sales?)
Several hundred.

- How much accumulated flight hours? What's highest? Experience?
up to 2400

- Likely MTBO, MTBF
3000 hours

- Compatibility with 100LL/autogas/heavily ethanol-blended gas (>=10%)
anything depending on what the fule tank is made of

- Installation weight, price, power, consumption
320 pounds fire wall foreward +/- 20 2rotor. 420 pounds 3 rotor.

- Noise and vibration
High noise 100 db 30 feet away. Depends on muffler. Low vibration.

- Models: 100/200/300+ hp, Rotax 912/O-200, IO-360, IO-540 equivalents,
250 HP 2 rotor. 375 HP 3 rotor. Both p-port.

-weight, price & consumption comparison.
see above. Price  $5000 2 rotor  $10,000 3 rotor. BSFC .47 cruise

What's our current knowledge of these issues? Please comment.

If we can come up with something like presentation kit, it would be
easier for everyone to keep one.

Cheers,
Petri
