I just learned that there are (apparently) two panel sizes available in a 29? Large and normal (or small).

1) How does one determine which one is in a given glider (without being able to easily compare it to another)? Are there dimensions or is there a simple test?

Look at this drawing (below) and compare to what you have. The small panel has taller leg cutouts - I believe these are not widely deployed so it it most likely you have the bigger panel.

2) Can you change between the two panel sizes easily? If you have a small can you change to the large and vice-versa?

You'd need to replace the entire panel pedestal that the canopy attached to.. I'm not sure if this leads to having to refit the canopy - seems like a possibility. I've not heard of it being done, but anything is possible with enough shop hours and composite material.
