Default Thermal Lift Dynamics

Try making a small right angle bend out of solid wire, and mount it up
on the panel so it shows a 45 degree angle like a letter-v (you may
have seen something similar on an aerobatic airplane). Use it as a
reference with the horizon to see if you really are banking at 45
degrees in a tight thermal. You may be surprised to learn that what you
thought was 45 degrees was only 30 or so. It's a very common problem.



In a glider with a reasonably supine seating position I use the instrument
mounting screws as a 45 degree reference. It's not so easy to do in a glider
where you're sitting up more because the instruments aren't so near the
horizon.
