Photos Of Performance @ 17,900 ft.

I finally got around to making that flight to 17,950 ft. As you can see by the flight timer (which had 3 minutes on it before take off) it took us all of 24 minutes to make the climb. We departed DVT, elevation 1460 ft. I had to level out after take off to avoid class B airspace and then we decided to head NE instead of NW due to cloud cover so I was not very attentive to the climb for a few minutes while we found a new waypoint and loaded it into the EFIS. I would think I could have made the climb in 22 minutes. I was still climbing at 500 fpm as we approched 17,900.
My copilot is Doug Peterson.
Here are a few details, some of which you can see on the EFIS.

RV-9, 0-320, 160hp, C/S Hartzell, EW: 1051 lbs. Take off weight: 1670 lbs.
@ 17,900 ft.: Indicated A/S 108kts, True A/S 146kts, Ground Speed 171kts. FF 6.4 gph
(Fuel quantity is really 28gals. I forgot to reset the totalizer, oops)

Just have'n fun!!!

Density Altitude

Congratulations Roger. Well done.
It's a pity it was so hot. You could obviously do better on a cooler day.
According to my Whizz wheel, 18000' at 3?C OAT is a Density Altitude of around 20,000'

I have the GRT screens in my RV-7 set up to indicate Density Altitude but the aircraft is still in the paint shop and yet to fly.
Maybe next month.
