You maybe correct but i do think the air conditions on day 2
contributed to the lack of improvement in our times. Maybe your
incidence was correct (not over elevated) for day 1 when more
stable/buoyant?
If you remember both of us had the dramatically change our pre load
to effect the change, this also may well be just the poor air
conditions.
My wing was actually flying on my 4th string models stick & tailboom
(not wanting to risk the trials model) but appeared to be very close
to its predecessor (tipped wing). The prop was a new 19" 28deg.

the low flying speed. The let down is then liable to be rubbish since
in effect the motor is too thin. You may have had the same trouble.
