What KS said. There's a screw and nut about which the vent scoop
rotates. Tighten that until you're happy with the stiffness of opening
the window. Don't tighten it so much that you break the window.

This weekend I did a high speed run to test some new seals I had installed on the rudder for vibration. VNE is 147 Kts in the Ventus, and so I only took it up to 130 kts IAS (yes I was only at 2000 ft MSL, so altitude was not a factor). At that speed the air scoop on the sliding canopy window suddenly popped open and scared the hell out of me with the sudden noise and rush of air.

Anyone have this happen, and is there a way to fix it?

Thanks for any suggestions.
Tighten the pivot bolt.
