We flew also without the canopy for a flight of 2 hours. The Blanik
L-13 flies very well even without its canopy.
We were expecting a lot of wind inside the cockpit but we had
just ...no wind inside.
The airflow is kept outside the cabin.

The only anomaly we found was that the variometer was less accurate.

Cheers,
Bruno

I'm sure it's been posted here before, but I just found this video of
a Blanik participating in a skydiving stunt and it made me wonder
about flying Blaniks with the 'sport canopy' mod as in this video.
Anyone know the specific performance penalties or of any aerodynamic
quirks from this arrangement? Off hand it seems like it would be fun
to occasionally 'go topless' in the ole Blanik at the club from time
to time...
