Lynn is referring to the LAEV prop by Butch Dias.
The electric variable pitch prop is designed to bolt to Tracy's PSRU.
This will allow a high HP, high reduction PSRU ratio with a low RPM

high

pitch

cruise setting for maximum MPG at any given speed.

One of the many features is the solenoid controlled brushes that

drastically

reduce wear on the brushes.

Here are a few pictures. Perry Mick will be building some carbon fiber
blades shortly and we will devise a severe torture stand to test the

prop

under the rotary engine's high power, high RPM  and gyroscopic loads.
This is not designed to fit a A/C piston engine as large 4 cyl piston

engines

have much more severe torque pulses. We will not test it on a A/C

piston

engine

nor do we recommend doing that.

That is one nice looking hub!  I'm looking forward to hearing how it all
works out.  Any thought on how well the prop would take the power of a

20B

engine?  Just settin' here dreaming.

Tom Kendall

It sure looks like it should. You want to send me your 20B and motor mount
for the test stand? :-)

Paul Lamar

All joking aside, I might just do that.  I'll have a complete engine in a
year or so, sans reduction gear.  Nothin' better to do with it!  Would have
to put all the stock stuff back on it since I won't have all the nice
goodies from Tracy, but it should work as a test stand.

Tom Kendall

It will be awhile. I am setting up to run the News Letter from Australia.
I'll be down there visiting our Australian friends about the middle of next
month and for about three weeks or a month. Don and Ian I will see you guys
in Perth or there abouts.
