I think you are over-analyzing this issue. The difference between flaps and no flaps is so small that you won't notice it. What difference does it make if a recreational flight is 300 km (no flaps) rather than 315 km (flaps)? In contrast, you will notice if your glider is hard to rig, has a poor trailer, or isn't comfortable or fun to fly. Those are the things that you should be focusing on. Amen, Brother Arnold! Especially in the conditions Noel describes, speeds will be low, and flaps will make an insignificant difference in the soaring performance. Where flaps can make an important difference is in landing. You will be able to put an ASW 20 into a shorter field than an Standard Class glider. The landing flaps (60 degree deflection on the original 20, 40 degree deflection on the B and C models) let you arrive more steeply, more slowly, and stop more quickly than an unflapped glider of similar soaring performance. My experience in Western Washington (2 flights) isn't enough to advise you about field size! -- Eric Greenwell - Washington State, USA * Change "netto" to "net" to email me directly * Updated!
