My board is 10X20 w a max deflection of 70 degrees, It does have 2 rows of holes. In my case the results were very dramatic,at 70 over the #'s I can get into the shortest runways. This summer I put it down on a 18oo' grass strip in northern Pa. Without the board never in a million years. I was hoping to get a nose down attitude on short final but it decends so rapidly I'm always nose high.

I retro fitted a belly board and in my case all it does is help slow me down on finals and steapen the approach angle (giving a better view over the nose). Once I round out it appears to enhance the ground effect and I float further. I think the board deflects the airflow down onto the strip. My ground roll distance has not changed, nor the distance I finish from the runway "numbers". My belly board does not have any holes in it, maybe I need some, just a thought. In my opinon I would not retor fit a belly board again, a lot of work and weight for minimal gain. Get the numbers right and it will all be easy (as Mark Langord said).

I came in on finals and did a side slip in a 75 degree X-wind. The speed was down to 90 mph when I crossed the fence and I was about 1m above the runway over the numbers. I was hoping to loose the extra 10 mph but no way. The throttle was closed at idle about 1000 rpm but the plane kept on floating. I then put the wheels onto the runway and held it firmly on the ground. The speed was indicating 60 while running with the tail up. There was still about 600m of runway left. I pulled back slightly to apply brakes but then the wheels hardly touched the ground and I could feel The KR wanted to get airborne again. At 40mph I could pull back on the stick and apply enough brakes to almost lift the tail. I had no direct forward visibility over the nose and was shocked to see the loop entrance, at the holding point, coming past at about 20mph. I went off the tar into the long grass and almost flipped over as the grass grabbed the wheels, spats and wings all at the same time. This was a quick stop. Even the engine stopped. Hennie repaired the prop well because the tips held up well against the grass. Only some marks on the red tip paint. I pushed the plane back to the hanger and left it there for the night as I had enough excitement for one day. In summery. I need to get the speed down to 80 over the fence or go around and try again if I am still above over the numbers. Wish I could fit airbrakes like we had on the gliders when I sailed at Donaldson Dam. If I can not get landings right within the next 3 or 4 times I am going to fit a belly plate brake or something. What can I do to loose the lift after round out?
