I went and saw a friend at spokane international yesterday and he helped me put some vg's on the back of the windscreen to help the effects of the air coming off and onto the turdledeck. Well I hardly ever use the flaps and to gain access to this area I pull full flaps on and went to work. We spaced the vg's 1.5 inches apart with the 15 degree angles. When I went to take off I was cleared for a 21(at)f departure with the winds at 120(at)13, I thought not a problem, then I called for departure and the tower asked if I wanted to take off 03 because the winds changed to 090(at)15, I said I'll take 21 anyway, noticing that the sock was pretty much going all over the place and the one at the beginning of 21 was still at a cross, which was closer to where I was. I pull on the runway and put full power and was amazed at how quick the tail came up and pulled back on the stick and shot up in the air. Soon, well very soon I was up higher than normal, then I had a hard down stick, so I put on up trim, thinking I did something with the vg's I called the tower to land on 07 and climbed up to 1000ft agl, turning was tough and then I thought, oh crap the flaps are on, I put the flaps back off and things normalized. What did I learn, the biggest, take off with full flaps is way cool. Next, do my check list with flaps off for take off, but then again having the flaps on full really make a nice cool take off, just don't forget to take them off. I did stick around and did a few touch and go's, kind of cool doing a landing on 07 at the same time a 737 is landing on 21. I did do a high speed run and one direction I got 105knts(gps). this was a down wind for 07 and on final I was doing 94knts, Which put me right over the approach for 07 (at) 2000agl, way cool, slipped down to land, droped like a rock. Need to make more test on top speed, but I do believe there was an increase of at least 5mph by installing the vg's to the back of the windscreen to turdledeck.

Good story Mike. Where did you locate the vgs? Closer to the
turtleneck, or to the windscreen? How far in from the outside edge? How
many did you use? Norm

I installed the vg's just in front of the screws that held down the windscreen, just in front of the turdle deck. I spaced them 1.5 inches apart, will have to go to the plane and count them.

This is a good report Mike. My turtle deck has always had a slight
vibration at cruise and possibly the VGs would minimize that. Do you plan
on placing pictures on Sportflight? I'm sure most of us would be interested
in looking at them.

as soon as I can get some pics I'll post, I think some pics of the funnel heater would be in line also.
