Hi Paul

I fly a Long EZ Paul and that 326 lb installation for the rotary engime from
Powersport could probably work but I would like it to be lighter. At that
weight, its basically the same weight as a Lycoming 0-360, marginal in my
application. I have heard of potential weight savings of 80 to 100 lbs with
appropriate attention to weight savings for the rotary. That would make the
engine incredibly attractive; 215 hp 250 lbs plus the prop would be close to
what I have now in weight plus 55 hp. Believe me , that would work. In my
application, the weight is very important.

With respect to the best engine in the 10 to 20,000' flight profile it
depends on the mission. For purposes of general aviation, a
turbine can operate there but its not optimal, fuel penalty. A turbocharged
engine could operate up to 57,000' but its not optimal----if it were 747's
would have turbocharged engines etc. Similiarly turbo's could provide
extraboost at sealevel but there is a price to pay and normally aspirated
do just fine. I am sure thats one of the reasons Alan has chosen the
LOM for the Atlantica for now and its track record.

For general aviation in the future, that light weight , super-light
high-tech rotary,
with special attention to making it as light as possible will be a godsend.
With all the money being spent ( our tax money ) on such things as the
Williams jet, something that may never work, why not put the effort forth to
making a real contender with promise a champion----but with venture capitol
money not tax payer money. By the way I just heard today that Eclipse fired
Williams---their engines had real longevity problems.

Have a Happy Thanksgiving !

I agree on the private capital. I think it might be a viable business in
another few years. At the price Power sport charges you would
think aluminum end housings would be included.

Racing Beat sells aluminum end housings for about $1500 each if money
is no object. Also Tracy's PSRU is about 15 pounds lighter than
Power Sport's PSRU. Ross's PSRU is lighter still. When we get the cooling
system figured out we might save another 10 pounds in less antifreeze
and smaller rads.
