Subject: [FlyRotary] Rev-2 flies
Greetings,
Well, N751RV, rev-2
made it's first flight today.
Good news- The
engine ran smooth, and quiet according to ground observers. There
were no leaks, or other problems, with the exception of the fact that I hooked
up the pitot and static ports backwards on the EM-2. That little
mistake rewarded me with a TAS of 0 for the flight. I fixed that
already. The plane now feels like an RV should, with much better
handling than the previous nose heavy version. This alone will be worth
the removal of the turbo.
Bad news- power is
certainly down from running 5 psi on the turbo. Once the prop unstalled
on takeoff, the rpm was only 4500, and it only went to 4700 or so in
climb. This is about 700 rpm lower than before. I didn't
notice the VSI during my brief climb to 1200 ft, but it felt reasonably
good. I'm sure it wasn't 2700 fpm like before, but there's plenty of rpm
left to improve this.
Some numbers- orbiting
the airport at 1200 ft, and 4700 rpm, the ASI showed 125 mph, with oil temp of
163 degrees, and water temp of 132 degrees. I made about a one
mile run at full throttle, and saw 150 mph, at 5700 rpm before I backed
off. Max water temp on climb was about 155 degrees.
Sorry, not much real
testing done, but I'm ready to proceed to that now that I got the initial
flight out of the way. Stay tuned.
Cheers,
Rusty (glad to be flying
again)
