 Our mini flyin in at Dietz Airpark Oregon went well.
 Philip Groelz and Steve BeckHam are restoring this old
 Power Sport prop dyno. Steve is building an RV3 air racer
 with long range tanks for the EAA 500 mile air race.

 Sitting around brain storming I had  the idea of starting
 a Wankel air race team and selling t-shirts to raise funds.
 Steve also has a large house with spare bedrooms and
 needs some expert help tig welding and machining.
 Steve has some nice machine tools and a large shop
 in a beautiful sitting on a private air strip.

 Steve,

 Just to confirm.  Your club prop can only test at one load correct?  If
 you fly with a C/S prop isn't it better to test with different loads,
 rpms and MAPs?

 Doug in Japan

 Two loads :)

The dyno came with a 32 inch diameter plywood disc which Everett and Steve
mounted on the protective cage to reduce inflow and test the engine under
different load conditions.

Hey that is a good idea. I saw that disk on these two pictures and
it never dawned on me what it's function was. Cheaper than making
a bunch of different size clubs or using a variable pitch prop.
Those guys are/were geniuses.
