1. Control surfaces. I understand them, but they do not understand me! They always attach the wrong way! They\'re ment to be parallel to the wings, yes? But they always end up sticking up in some manner of 90 degree angle! Why is that, and how may I fix it? This is a new feature. They didn\'t used to work like that. But you can still get horizontal surfaces by putting them on the wingtip. 2. Air-breathing engines. What, why, and how, gentlekerbs? Basically, these will not work in space. Less air - less thrust. 3. Trim. Is that...no, I actually have no idea. What is trim? Why would I want it? And how does it work? Elevons and airlerons. Like what most jet airliners use. 4. Mk2 and Mk3 fuselage. I apologise for my ignorance, but *what* are these? Mk2 is the smaller one. Use these on things like fighters and light bombers. Mk3 is the larger hull type, and this is for airliners, heavy bombers, and crazy Tim_Barrett designs. 5. RCS-Port-Linear. I know RCS. I do not know Port-Linear. This was in C7\'s Flight Pack. It\'s an RCS port pointing straight outwards, rather than to the sides like normal RCS. Used for pushing the ship around, rather than moving laterally. 6. Avionics Package. It says 'sensors' and 'computer'. Guess what? - WHAT? It\'s an ASAS, only smaller. 7. Rams. Evidently not meant for battering. Someone explain, please. Ramscoop, I think. Probably just something to make it look cool, and to give it the impression of looking like an engine. Haven\'t seen it myself. 8. The Tail Connector. It looks ridiculous, but surely it has some manner of purpose, yes? It\'s for putting tailplanes on. Basically, this is where the rear wings go on a small aircraft. 9. I accidentally dropped my original Kerbonauts (Bill, Bob and Jeb) in a command pod cum parachute somewhere half a continent north of the KSC, along the coast. How will I best go about retrieving them? Fly a plane there? Or just go up into space and try to drop down next to them? I just want to make sure they\'re OK. Plane. You\'d have more controlability, though it would take longer. Hope this helps.
