Might have "just" made it into the club yesterday, but check that fuel burn with 201 knots across the ground! 7.5 GPH well lean of peak.

There is a big difference in hearing other's amazement at these machines that they've built and actually experiencing it yourself!

Default Full Power Run.

I finished up the wheel pants and decided to see what kinda speed gain I got. Everything forward level at 900'. 198KTS / 227MPH.
Still working through Phase I but I'm starting to see the light of Phase II.

Do you mind telling us what gain you saw with the wheel pants on?

I have been downloading the Skyview for every flight, mainly checking on the engine temps but comparing IAS for the same power settings this is what I get.

Going from no fairings to just the wheel pants 3-6 KTS.
Installed gear leg and intersect fairings & painted all gear fairings. 7-10 KTS.
A total of 10 to 16 KTS gain in IAS. This is in no way the most controlled test it was just pulled off the downloaded information.

Van's post for RV8 top speed 180HP solo is 213 MPH I got 228 MPH Don't know how much the Fastback Canopy mod adds but so far I'm happy with the speeds.

The canopy question is a tough one, since I doubt anyone has actually flown the same airplane with a slider and then a fastback tip over. Perhaps a ballpark is possible. Looks like you have a nice, clean 180 horse -8, largely stock except for the canopy. There must be more than a few with the same engine, prop, etc. Have you calibrated your airspeed yet, using three-leg NTPS runs?

Jesse - Nice fuel burn! I was surprised when indicating 202 kts GS on my second flight - no pants, gear or intersection fairings. Did you fly your brother yet?

Cool Made the 200 KT club

On a recent trip from Pagosa Springs, CO to McKinney TX we showed 222 KTS ground speed. Mixture was 40 degrees LOP, 6.7 GPH, 2400 rpm and airspeed was 162 KTAS. The 566 NM trip took 3 hours 33 seconds takeoff to touchdown. I'm just glad that we weren't westbound!

Winds were picking up a bit above 6500 or so today, so while just bombing around, thought I'd see what I could get around 8500' or so (didn't bother climbing higher as it was getting a bit bouncy...)
