A long time ago, when such things were not censored by the current regime of political correctness, I had the opportunity to fly with a true greybeard bush pilot. His leather flight bag was battered and bruised from its many years of being stuffed in whatever spare space could be found in the long list of airplanes this man had flown. In conversation I learned that one of his most prized possessions was a rare sticker on that flight bag, purportedly supplied by Pratt & Whitney. I couldn't help but smile when I read that sticker:
"REAL MEN FLY ROUND ENGINES"
Your RV8R ranks right up there with the hairy-chested, manly-men's airplanes of yesteryear - the Grumman "cats", the Bull Stearmans. You have every right to stand beside your machine and beam with pride, knowing you have built something totally unique, something which earns you the envy of so many who would not have dared embark on such an ambitious project.
Go fly her for the sheer joy of flying an airplane with a round engine, and know that, on the ground below you, men and women, both young and old, are looking up and feeling the goosebumps form as they delight in the throaty rumble of your radial.

For now, fly some three-leg airspeed calibration runs. After some hot weather testing, throttle the exit. The big hole in the front is just a low Vi/Vo intake.

Brian,
Your plane is not about top speed. It's about being something very new and exciting. It epitomizes the spirit of E-AB flying and building. No, your plane doesn't and will never match the speed and narrow expectations of those who only appreciate this facet of the RV world. But you do have a plane that will draw the interest of pilots with any minimal knowledge of light GA and experimenting. People will walk right by the fastest Lyc powered RV to come see your plane. Enjoy it for what it is. A very cool looking, very cool sounding, radial powered RV.
Hope to see you and your plane at a fly-in one day!

AMEN!
For those of us who have been around a while, aviation has come a long way leaving us with sights, sounds and smells in memory only, except maybe at OSH when the War Birds do their thing.
A few years back I shook hands with Gunther Rall at OSH the year before he passed away, it was like shaking hands with history, the same hand Adolph Hitler grasped several times as Rall was awarded another metal for his feats during the war. His life was complicated in that his wife was under constant scrutiny by the SS because she helped a Jewish family escape arrest.
Anyway back to the round engine RV-8, I think its a great accomplishment. As Brian said yesterday, I did it to please myself - and you've also pleased others just by doing it.

The above comments really resonate deeply. While there's something magical about any airplane a round-engined plane is just something else. Who needs speed when you get a huge plume of smoke with every start and admiration with every turn?
Big congrats (even makes the lurkers come out)!

My first flight complete!
Test flight number three is complete! This was my first flight in the airplane, and all I can say is WOW! That thing is a lot of fun! A problem has crept up with the prop governor. It doesn't want to go to high pitch in cruise. So I'll work with flybox to fix that issue. Also I'll need to add an air oil separator as I had quite a bit of oil coming out of the breather. All of these are normal developmental issues. The Rotec Aerosport R-3600 is running great! Once these two items are fixed flight testing will resume.

Electric prop
You may want to consider running the pitch of the prop manually. We Subie pilots have alot of experience with electric props. The automatic modes have had problems with keeping up to rapid throttle changes and you can end up with engine over speeds and lack of performance on go around. A manual mode also saves wear and tear on the pitch mechanism since you only change pitch a couple of times each flight.
We set the fine pitch stop to be like a climb prop giving max RPM at about 120 mph with full throttle. We set the course pitch stop to give desired RPM at cruise speed. This way the pitch is never outside a usable range. I have a bright LED that comes on when the electic motor hits the stop (it senses the stalls current from the motor). I could use a finer pitch stop for better take off but I don't need more and I like to keep my engine RPM down for longevity.

Here is a great outside view of test flight three!

Seems we have a recurring theme here. Ya'll quit apologizing like the family does for a ditzy cousin ("...but she is such a sweet girl").
No thinking person expects the 8R to be fast. After all, it's only got 150 HP. However, I'd bet the next Oshkosh beer tab that it will go faster with a bit of development. And God knows, none of us need an explanation as to why it is cool.
