On Saturday 7 July RV ZULU X officially became an Airplane.
The kit has been done ready for a week: http://www.vansairforce.com/community/showthread.php?t=88164
...but we had to organise the test flight....
We have winter here in South Africa and the fields are brown with dead hibernating grass, hence the dull landscape...
FIRST TAKE OFF, keeping low initially to feel positive Aileron and Elevator response before climbing
Climbing for the heavens to get maximim safe altitude in case emergency
First Landing after 30 minutes circling the airport
Taxi Back,
Nice Picture, before first shut down
Thanx to Jan and Hugo for the support on the testflight day, the famous RV grin, all thumbs up!
A nice Photo taken just after I got out and closed the door
After the initial flight I took cowls of to inspect, all good, so they went back on ready for next days flight...
Then on Sunday I took her out to burn holes in the sky, to get the new motor to run in.
On the High veld (our airfield ground at +/- 5500 ft ASL) we loose power due to air density and less oxygen. Lycoming recomends 75% power for the first hour or two and then altenating 65-75% setting.
So basically WOT to get 75% power up on the highveld. I cruised around for 3 hours then another 2 hours at high power settings on Sunday.
I can confirm she is a 200+MPH airplane at 75%power.
The Autopilot works (I set it at 7500 ft Alt hold) then just steered the stick left and right high cruise 75% power to stay within my 100KM proving flight radius.
Flight Characteristics: Heavier than RV7, but more stable, The Stall is benign, with only 1 up you need a lot of UP trim coming in for landing.
A picture from the Dynon, I still needed to configure some items in flight AOA and MAG for XW during the photo time. Interesting to note at 75% power(24/2400) IAS = 180MPH (Dynon knows Alt and Temp so can work out) TAS =204MPH, GS (from GPS) =215MPH @ 7500ft ROP 53l/ph. TEMPS all good.
Cant wait for this weekend to explore the test flying and capabilities
Kind Regards
