I read in another post by Doc Holliday that he uses a piece of carpet to take planes off. I asked a friend who works for a flooring company if he had a piece. He came up with a piece of linoluem, probably 10 feet long.
Two problems
1. It is smooth - when I pull on the lines to tighten them just before take-off, the plane slides toward me. This has led me to believe that with asphalt and short grass, the wheels have resistance when I tighten the lines.
2. The linoleum has humps in it when rolled out - if the propeller doesn't have a lot of clearance, It hits the linoleum and it's hard to take up - so we adjusted the wheel struts to raise the planes.
I think I will try carpet when I find a piece.
Has anyone had other experiences with portable runways? I can't haul an 4 x 8 board, maybe 2 2x6's.
