Since all the ASW20BHs have passed their time as an H, isn't the biggest
performance difference between stock ASW20s the MGW of the 20B? Doesn't mean
much at reference weight.
Heard of people who have removed the pitots, put the turbulator tape over the
blow holes of the C.
There's a "Frankenglider" or two with the great combination C fuselage and A
wings.
For those unfamiliar, the ASW20BH was the limited time at a higher red line
"Hobbs Special", all low serial number B models raced in the '83 Worlds.
Of course, the best 20s are not as they came from the factory, but ones
modified by Rick Wagner. All the ASW20s he saw were EXP. Rick's recipe:
Cut off inner end of flaps, bond to the wings.
Build better wing root fairings. Think ASW27 with the fairing extending forward
of the leading edge to the canopy rail.
Cut off outer end of ailerons.
Cut off wing tips. Discard.
Build new wing tips. (looked between the LS-4 and original ASH26E curved tip)
If it doesn't have a tail tank, add one.
Modify the trailer so the wing root fairing fits in the roof and clears the
floor, and adjust tip hold downs.
Wil Scheuemann's recipe was more like:
Remove skin of outer trapezoid.
Replace with same airfoil as inner panel.
That would probably spin like a top if you didn't behave, but go like a bat
out of hell.
But unlike H301 Libelles, there are no Scheuemannised ASW20s, with or without
Sebastian Kawa.
All those ideas were pre- wingletty things.
Unfortunately the best example of Rick Wagner modified ASW20s was destroyed a
while ago. Believe Rick's wingtip moulds have been lost, and none of the other
modified 20s have all the mods. One has the aileron, flap and tip mod but not
the last version of the fairing.

Subject: [Aus-soaring] ASW20's
If four ASW20's, one of each variant (a, b, c, f) were put in perfect in flight
test flying factory conditions - all with the same reference weight of 400kg.
Which one would out perform the other? Or, would they all perform identically?
Keen to hear reasoning if one knows the answer (I don't, hence the Q).
Cheers,
WPP
