Hi again fellow flyers over the ditch. Another nice site you have there Odakyu-sen, i live in a high rainfall, sub tropical area and we came up with a good solution which made a lot of sense... When you make a new launch, if you can add in a "forgiving factor", occasionally a pilot will be glad you did! If you can "landscape" the take- off, try adding a earth ramp. This will give the designer the option of steepening the run and also making the pilot point exactly the right way too. As equally important is the fact that the gliders wing tips are further from the ground, allowing for some minor poor techniques, as I heard on John"s launch with his rh wingtip. The last finishing touch is to cover the earth ramp with astoturf, {we used second hand pieces from a renewed tennis court}. The grass still grows on either side of the astroturf however because your "ramp"is so much higher,{ we added a lot of dirt, 800mm?} you can let the grass/weeds get away for longer months between working bee"s.
