Perhaps I am gutless and don't have the gene, but I don't see anything

wrong with letting someone, for $30,000 or

more,  put in the time to produce a package that has been wrung out.

I want the advantages of a flying behind a rotary, not the

R&D the experience of building one.   I am often shocked at the lack

of knowledge in what I read here (in addition to the very

creative, well thought out, state of the art work). But, I do fear

that rotaries won't catch on because of fatal amateur efforts

giving them a bad name.   Tedd, I would be very interested any sort of

a similar forum for your product or a way to

keep

updated.

Dear Unsigned, There is no hostility toward powersport. I have even

inquired about

 some of their products. You should know that the current owners acquired

the

company for a song from the original Everett Hatch run co. The rather high

prices

of their equipment puzzles me. They spent lots of money on items not

really needed,

IE perpheripal ports. Not enough study on the basics, like radiator

location and sizing.

They certainly have not "wrung out" all the problems as their plane still

has cooling

trouble in hot weather. They have modded their much ballyhoo'ed new

cowling to a

larger scoop and still have problems. This is despite the cautions given

them by

Paul and others on this forum. Their system is very well finished, but

finish alone

doesn't mean everything works right. Their re-drive seems well done

although a little

heavy but costs at least twice what most others do. I wish them well, but

they

need to communicate with those of us that will be their customers. Bill

I am new to this forum and know nothing about rotary engines other than they
don't have as many hand grenade problems.   My desire is to have a high
horsepower power plant for an airboat which has no weight requirements and
has lots of room for coolers and radiators of large size.    I need to have
a power plant that will put out 750 horsepower with a high reliability
factor and don't care about weight nor space.  Gearbox reduction for
propeller needs to be reliable and handle the horsepower  but can be any
size.  Airboat people are already using good props that can handle the
horsepower but I haven't seen any rotary engines although I know there must
be some.  It seems like a three rotor with turbo might fit this requirement.
Several of my friends are using big block chev engines putting out 700 to
900 horsepower but they hand grenade them often.

Any idea about where I might get more info on this subject?
Boy, you guys sure bash this scoop problem pretty well.  I know cooling is a
serious subject with airplanes.

Clif- 

Contact Racing Beat Clif. They have just what you are looking for. 1000 HP.
350 pounds. You will need an old Bell 47 Helicopter gear box for the
prop.
