I'm pretty sure there is no or very little performance hit for flying
the 1-26 open cockpit. My old club had one, it was a blast but it got
cold at cloudbase.

At one of the 1-26 Championship contests within recent memory, there was
an effort to get as many competitors as possible flying with the Sport
Canopy. As I recall (I wasn't there, I've only been to two of the
Championships) there were six or seven 1-26s competing with open
cockpits.
