Thanks Vic, but itís in for the winter. The runway is grass and does not get plowed so no flying until we get a thaw.
I had a similar problem a few years back. I left the canopy closed on the ramp to keep the heat in the airplane on a 20* day during a trip to Lima OH. I then launched and climbed like an express elevator to 4500í, about 10 min later the canopy cracked with a bang.
Scared the you know what out of me.
