am starting this subject here at my blog.
i was running it on the open but got too many negative or non related posts so this way i can keep this clean.
it was here:

so, welcome all who want to follow up that thread
i said this at the beginning:
am starting a forum with the purpose of discussing the design to reduce the planes sinking speed.
the idea is that with the minimum sinking speed the plane may stay longer-and perhaps catch thermals easier.
please, only bring your experience or ideas related to the subject.
sinking speed
am bringing this from another thread, where we were discussing another subject:
"at the present time am performing tests to find out which is the optimum wing loading to stay up as long as possible for thermaling.
and building too light could make an airplane to sink faster after all. i have several 2 meters e-gliders, and the lightest flies noticeably slower, but that, even if very impressive, not necessarily means lower sinking speed. could be that it just does not penetrate enough.
the only thing that occurs to me is, besides timing them from same height in still air, is checking sinking speed and forward speed too. "
>>>after testing, i learned that the lighter, slower, sink faster, so after all, there is a limit that, if you go beyond certain weight, the plane just does not penetrate. period. but this can only be learned if you check the time from
