This is a OSH picture of the Power Sport gear box prop shaft
and internal gear. Power Sport sold at least three firewall forward
$17K Mazda engines before OSH. Two went to akro guys. Looking at this cannon
proof prop shaft I can see why. Beats the Lycoming akro engine hands
down. The downside is the box is quite heavy at around 60 pounds.

The PS RV6 215 HP peripheral port rotary had at least 41 hours as of OSH
and was going 195 MPH with the wrong prop at the rev limit of 6250.
They have an MT variable pitch prop soon to be installed. Still has
minor cooling problems. I will fly up to see them in about a month and
give you guys a report on how it is doing.

Ray Richardson owner of Power Sport told me they plan to run the Apple Valley
to Copper State race and win the $500 Everett Hatch Memorial Prize in
October. The aircraft rotary engine cause is moving right along.

Gee, I looked at that boiler plate picture you sent but I just can't see
where they're hiding the 60 lbs. ;-)

Did you calculate all the volumes and multiply by the material density? :-)
You are not too good at guessing weights as you overestimated the weight of the
stock 87 turbo exhaust manifold :-) Just kidding Jeff!
