One thing i have experienced , is in cold weather (below freezing). I really have to watch my landings, (In summer the same landings or rougher ones have no effect). Just a hair to rough will sheer my 4 nylon gear bolts out (10/32). Mind you this is better than ripping the bottom out of my LT-40 (is converted to tail dragger). But it happens very easily. Will probably add one or two more, So that i will be changing them less ,but still able to sheer off if need be. This thread just gave me a new thought though. What about wing bolts in cold weather? Hope this isn't to far off topic. Not meaning to hijack your thread.
