Most of the "TEAM" made it out today for a morning of flight testing. We really had a bunch of fun "Tweaking" the Yak into shape for it's two successfull flights today. SteadFast has flown about 10 times in the past 10 days with favorable results. I dove the airplane to 335-340 KIAS bottoming out at 7500' while running 40" and 2700 RPM. I was carrying some unnecessary aileron trim so I chose not to let it accellerate any farther as the roll force was getting quite noticeable. We were having a problem keeping the prop RPM under control at the lower RPM's 2300 and below and high TAS. (220+). I sent the prop governor to Wings West and they bumped up the PSI to it's rated pressure of 450 from 425. After spending a couple of hours with JR and Mike Belmont of Stockton Propeller, we had an Idea on how to make the 23E50 hub and dome work in our favor. After some thought I was able to increase the coarse pitch to a higher value than we were able to previously attain. We can now run 1800 RPM to indicated speeds of 280+(thats all I tested it to). So with the prop squared away, we will now put the big spinner on and hopefully run that up at PRS. The gripes are becoming fewer and smaller so we can begin to relax a bit and enjoy flying this little rocket! I have a few T/O, flyby and landing vids I will post as soon as I can figure out how to minimize them again.

PS, that 340 KIAS was in a dive!
