I never flew it (or even quite finished it), but I did get its launch lugs glued on, and they all slid smoothly on the launch rod when I "test-fitted" it.

The concern would be binding under non-ideal conditions (rod flexing in the wind, flexing under stress of launch, etc.) In any case, though, I think at this point I'm pretty committed to putting the lugs in the two rear hangers and leaving it out of the front. I think that will be fine. Haven't designed those little assemblies yet, though; still trying to decipher the drawings you sent me.
