Some may think this a cheap shot, but what the heck.

Believe it or not some pilots fly gliders with fixed gear. They even fly
them
X-C and make land outs. They even stall/spin them.

Too many people in this sport think you need ALL the bells and whistles
and a
$100,000+ glider to be a "real" glider pilot. That attitude is hurting
us.

I certainly would not use the word "need" with respect to a
glider AOA indicator.

And yes, cheap and simple is important. Perhaps the cheapest idea
is simply the ol' harmonica style Cezzna AOA indicators, one
mounted on each wingtip of a 1-26 (easier to install on a metal wing,
and the 1-26 is a glider with more than it's share of stalls
leading to fatalities).

Then, if added complexity is warranted, a small switch on the
spoilers which deactivates the audio vario when the spoilers are out,
so one can now just barely hear the stall horns.

Ideally, it would be nice to have removable wingtips, so
one could experiment without modifying a whole wing...

Perhaps there are other types that would have this feature
to allow inexpensive experimentation. Then maybe try the electric
AOA tabs too...

Tape two yaw strings (which then become pitch strings) on each side of the
canopy at the lowest and most forward part you can still see. Fly once with
a grease pencil to mark the inside of the canopy at the string positions for
best L/D, minimum sink, and stall. By using a string on each side of the
canopy, the error introduced by inadvertent yaw is obvious and can be
eliminated with rudder.

The string position for best L/D, min sink, and stall will always be the
same whether the glider is ballasted, empty or in a steep turn - although
the airspeeds will be very different.

The string angle difference between minimum sink and stall is large so the
bright red, wiggling strings angled up steeply are a good visual stall
warning.
