So, we're having incredible weather today in southwest Ohio (75 degrees, blue skies, calm winds). And figured I'd try seeing how my 12 does vs POH. Mind you, mine does not yet have Wheel Pants on. Turns out I'm beating (according to Dynon) the POH #s. But, admittedly, I'm not at gross. This was full fuel + me (190lbs) and some miscellaneous stuff (towbar, quart of oil, etc.). Net, lets say I was at 1075lbs or so. 755 (empty) +200 (me with stuff) +120 (fuel)
POH says @ 7500 ft I should see the following KTAS:
5500rpm - 114; 4.6 gph
5000rpm - 101; 3.7 gph
As you can see in pics, I'm seeing the following @ 7500 ft
5500rpm - 121KTAS
5300rpm - 116KTAS
5200rpm - 114KTAS
5000rpm - 109KTAS
As you can see, my fuel burn # is way off and reading high. Need to adjust K-factor I guess. I do know that I burned about 7.4 gallons over 2 hours. So I at least I think it's just a matter of dialing in the k-factor.
Either way, I'm pleasantly surprised and happy with the speeds I'm seeing....especially if I'll get another 4 knots TAS with the wheel fairings on. Based on those #s, feels like ~5200-5300 is the sweet spot.
Anyway, thought I'd share as I always see people asking what performance they're getting. This was a pretty standard day in that temp was 54F at altitude.
LOVE THIS PLANE!
