This past week I purchased an ASW-20CL. Wondered if anyone has any
thoughts on the handling qualities of the 2 configurations. The 15m
version is equiped with Nixon winglets. The previous owner never flew
with the extended tips so could not offer opinion or advice.

Thanks, Gary Adams

I have flown the 20b and the LS-3a with the 16.6 wing tip extensions
and IMHO neither did much to improve the glide and just made the roll
rate noticably slower. They may have just extended an airfoil that was
optimized for the 15 meter span which had been chosen to give a gentle
stall and didn't increase the performance when extended. I believe
only SH got it right when extending the wings with their Ventus and
Numbus. Schleicher figured it out and changed the last 10' in order to
get the desired results in both the 15 meter and 18 meter
configurations on the 29.
Just my observations & opinions,
