I try to check everything, too, but just realized I haven't checked anything on my WM Ultimate 30 for a year or so.

This plane was a little finicky, at first, and I actually landed it missing the top wing, once. Had to fix the wing support, and haven't touched anything since (well, once, the muffler) in about 150 flights. Let me tell you, though, at first it was every flight! Here's why.

They supplied a metric screw and blind nut to secure the bottom wing. Every flight, the darn thing would work loose. In desperation, I cut a length of fuel tubing, slid over the screw on the blind nut side, and snugged it down. I've carried it around (or hung it in the garage) fully assembled, since then! Never look at the servos, engine mount, or linkages (except externally) - which is rather a departure, for me.

I guess after the wing quit coming loose, and after checking all the other stuff and finding nothing wrong, I've just become lax. Maybe I'll go out to the garage now, and go over it. All my other planes get the critical eye, each time I assemble them.

Good thread.
