Uh oh, good thing Ed helped me get that 20B powered RV-8 project
moving.

Subject: [FlyRotary] monster prop
shrinking a bit
Greetings,
I talked to Clark
at Performance Props today.
I’m going to go ahead and send my prop in for final finishing,
since the engine is down anyway.
I reported that I’m currently getting 6000 rpm at 100 mph in climb,
and 6800 rpm at WOT 8000 ft.
I requested 6500 rpm in climb, which will make top RPM about 7300
WOT at 8000. He’s got to run
the number, but the rough estimate is that the prop will change from it’s
current 74”x88” form, to about 72”x82”. He seemed very excited about
what this will do for my performance, in both climb and cruise.
I told him I need a
guarantee that it will beat
Tracy :-)
Seriously, I told him that I was getting 2400-2500 fpm climb now, and
wanted 3000 fpm. He seemed pretty sure this change can get me there
:-)
Cheers,
Rusty (Tracy's going
down)
