Dorsil,
Sorry to hear that you had a bad time, but glad that it turned out ok for you.

As far as the screws go. Here is the break-in procedures (and continued maintenance) that should be taken on every plane, no matter if it's a kit, ARF, or RTF. The plane needs to be assembled and every screw, nut, bolt, clevis, etc... needs to be tightened. This means everything on the plane. If you break-in the engine on the plane then everything should be checked again to make sure it's all still tight. This is especially true for the engine, check everything to make sure it's still tight (including the head bolts because they can and do loosen up on break-in). After your first flight it's time to recheck them all again. After that you need to set up a maintenance routine of how often you check them all again. Some do it a couple time a summer, some do it a few times a month, some do it after every day at the field. Myself, I check everything as I'm cleaning up the plane. If I find anything loose I'll bring the plane into the shop when I get home and go over it all again to see if anything else loosened up.

These planes aren't fly and forget. You have to check them to make sure everything is still tight on them. I've seen pilots that have planes that are 10-15 (and more) years old, and if you ask them I'm willing to bet that every one of them have a routine of checking their plane over.

Hope this helps

Ken
