I have seen 60 size planes (speed) crash from the hinges pulling out.The builder claims after textbook installation of the hinges he gave them a good pull to insure they were anchored. I guess vibration,position and wicking can affect the outcome, to pin for me is just insurance.On a ARF pinning with a pin cut to length from the under side with a drop of CA would be a cleaner installation. ANYONE DONE THIS??????????????????????????
