Schweet Well, here's my testing, without looking too much into the "manual". In my opinion common sense should be enough for a click and fly game as KSP to make some planes, so I might be a little... frustrated at you. But once that is fixed, this mod definately comes high on the prio list to install. The most annoying thing I do consider a "bug" is at the 2:55 mark. Watch this, highlighted out my testing on the mod: http://www.twitch.tv/sceppie/b/334680987 Also note that parts snap off because of crossusing mods, so not really your fault. Although attaching an engine shouldn't really break a fuselage. Edit: Oh boy, I'm embarrassed the way I complain about "the mod author" in the first minute... I've definitely not shown the good side of me there, my sincere apologies :/ Edit 2: I've read up on "known issues" I guess I should've done that earlier. This is really the annoying part what makes the mod troublesome. It's like an achilles heel. Come on collabs, make some noise for vvaris here!:
