I bought one of those Airgizmo external control lock thingies (I'm using it at the top of my rudder) and I cannot figure out how to easily tighten it down. I was in a hurry when I bought it and declined the nice-gent-at-the-counter's offer for free initial on it (to myself at the time "how hard can it be"), uh-huh one of the Hazardous Attitudes, you got me. Any tips?
Looks like you are not alone. Check out the reviews here: https://www.amazon.com/Airgizmo-AC2-AirGizmos-Gust-Lock/dp/B00KEFJH28 Then there is always yootoobs:
Yup I see the problem. It's an engineering one. I am going to take a file to mine to see if I can fix it. Will report back if I do, for follow-on people looking for solutions.
A few strokes here with a coarse file and the strap is much more easily adjusted. Will report back if it no longer locks the control surface in place.
