Hi, Paul. First of all, let me say that I am very happy to see

another

rotary engine aimed at the aviation marketplace which could further

our

efforts to get more rotary aircraft installations.  I have always

thought

that the Mecanair was a very compact, well engineered engine.  I was
dissapointed when their website no longer showed their engine a

while

back.

I really wanted one.  I would have shelled out the bucks to buy one

of

those

engines.  Unfortunately, I'm so far along with mine at this time,

that

it

would take me longer to get airborne than to continue with my

present

installation. (I have it running now).

     One area that could possibly use improvement, however is the

alternator

belt. Looking at the last picture in the message you sent at 6:48

p.m.,

it

appears that there is only one alternator belt, and it passes

through

the

bellhousing/casting through a vertical slot. Two alternator belts

might

be a

nice feature.  That being said,  I guess that if I had to choose

between

a

single belt on the water pump or a single belt on the alternator,

I'd

choose

the alternator. I'd much rather loose an alternator than a water

pump.

Do

you know how their water pump is driven?    Thanks for sharing those
pictures.   Paul Conner

There are two alternators. One is gear driven like the water pump on

the

back of the engine. Same goes for the aircraft vacuum pump.
This is a first class aircraft engine in all aspects. The next hurtle
for Mecanair is the firewall forward overall package. Most of that
challenge will be effective water and oil radiator sizing and ducting.

Changing that front alternator belt would be a bitcxxxx! You'd have to
remove the psru...........?
