thanks for your fine reply on wing tip stalls,

I tend to concentrate on the flying and building... and leave the book work
for late at night.

I have produced a number of DVD's on the Pioneer which to me is a most
interesting glider that needs a lot more study.

As to the root stalling first -yes that is as we found it but it is very
gentle. Dave Wells tufted the wing root and yes it progressed from the root
to the tip. In my movie it readily shows that when the one attempts a stall
the Pioneer stays at a certain angle of attack but it can slowly go off to
one side but it can be controlled by the rudder.

If you would like to view this for yourself I will send you a DVD of a
cross country flight with a save from 700 ft agl and include a number of
attempt stalls and a high speed run to 95 mph. I would like your input.

In a turn the Pioneer will not drop a wing tip... I think this needs further
investigation and the new Pioneer III with a modern arifoil, that should fly
this year, will be another glider to study.
