Default Gotta love this

Bet most of you have seen better..Coming back from San Jose to San Diego yesterday had a 34kt tailwind. Ground speed over 200kts!!! Of course I put money in the bank going up with a 18kt headwind but that was soon forgotten..

Happy Flying.

Down low in Alabama yesterday, trying out my latest experiment.....203 TAS, WOT in level flight, on autopilot. No, I won't claim precise calibration, but it's close. I'll be doing NTPS 3-leg runs in the near future. Sorry about the blurry shot. It was a bit bumpy into a 30 knot headwind. Probably go a little faster when I find some smooth air

(Postscript, two weeks later; Did a 3-leg at 9500 feet while indicating 185 TAS. The numbers were 194/45, 179/169, and 182/292. That calculates at 184.9 knots. Pretty accurate. I'll bet the 203 in the photo is equally accurate.....or at least over 200.)

The Lycoming power chart for the 390 assumes 28.0" Hg at rated power. The GRT Sport percent power indication is based on the OEM power chart. In this case I have 28.6".....through a filter.

Yeah....book is 105 lbs per hour minimum fuel flow for 210 HP, or 17.5 GPH. As I do not own an oil well, full tilt boogie down low is reserved for special occasions

Not leaned out when I took this, and higher the winds backed off.
M01 to KRID was 1.8 hrs

Default 212 Kts RV10

This was heading to Osh 2011. It was one of those days that no matter how far you pulled the power back, you were going to be early for customs. We left Williston, ND direct for Osh, 675 NM. Notice 38.3 Gal remaining at Osh so we still had lots of Safety for a hold if it happened. I have the HWA tip tanks. The two legs was just over 1100 NM total and we got in to Osh just after lunch. For the keen eyes, the AOA was not correct.


Here you will see the great economy after we leaned a bit more. Not running LOP as I do not find you can without big speed penalty in the teens and up. We lost a bit of speed but still had over 200kts at 23plus miles/gal.
