Alright guy's I give in! what are we going to use.

Any recomendations on props for our use with the outputs of 200 to 300 hp.
Regards Don Dunbar

Make your own blades Don. Anybody that can design and build their own
PSRU can make their own prop blades. :-)
Here are some pictures of Butch's variable pitch hub jewel. As
soon as Perry gets the blades made and I get the dyno done we
will give it a severe gyro torque test with my turbo engine.
Sorry about it taking so long.

Hi Paul/Guys;

      Or.......better still, have Perry custom make the blades for you. That's
precisely what I am planning on doing due to my ignorance of goo processes.
Once Perry makes these blades his tooling and technique will be up to par.
FYI......Notice the big ass Delrin washer on the Shank index fixture? It's to
prevent the goo from going past a pre-determined point (Dam), and provide an
accurate nice flat surface which will save us an expensive lathe turning
operation.

I'll take some time now to clarify Paul's attachments 1 & 2 before ACRE gets
bombarded with questions. Pauls Sun-Fun-No-1.jpg is actually LAEV-2........The
LAEV Parts-4.jpg are actually parts belonging to the LAEV-1.........Yes I
designed and built two (2) LAEVs.

The LAEV-1 is larger and heavier due to having larger expendable shank ball
races and heavier Blade Shanks which are capable of 400 HP plus :)

The LAEV-2 is much lighter due to smaller removable, replaceable split ball
races fitted on a lighter designed Blade Shank. This obviously required a
smaller and lighter Hub shell. If you carefully study the four attachments you
will notice that there is a world of difference between the LAEV-1 and 2.

The big question of WHEN??.......Perry has recently informed me, the Blades
will be ready sometime in November. Paul already has the Dyno pretty well along
and is pretty far along on his Turbo engine planning.........Paul chime in on
this, let us know what's in your noggin :-)

I will soon be gathering cost information on quantity runs and will keep all of
you posted.

Well the intake manifold is almost ready to cast. It looks like the first of
the year before I get my turbo engine running. Still need to do
the intercooler thing.
