Are these parts tested? Do they have any errors? Will they bug my game?

I have done exactly that thing for my tank destroyer, but without triangles and other shapes it lookes like a oversized clam. If you need ideas for textures look at space engineers armor.

I would appreciate i you could make some sorts of thick armor with more chrash tolerance and one armor piece with like a hole like thing for inside almost gun mounts. Then i can make real tank destroyers and mobile artilleries. Also could you link the mod in this thread please.

When you launch a missile in the air it is already going in the speed your aircraft is. Let me explain. Imagine an ice cube in a square box with wheels. The box has a motor. The box is now traveling at 10m/s. Everything in the box is traveling at the same speed. The box brakes and launches the cube forwards in the exact same way that you are lauched forwards in a car when it comes to a sudden stop. When you have your seatbelt on it slows you down with the car becasue the seatbelt is attached to the car in which the joints on the missile are. Then we you disconnect said joint the same thing happens when you don't have a seatbelt and no seat to behind you to hold you in place. Since a human can't accelerate when sitting in a moving car you can't keep up with the car. But now imagine that you have rocket boots that are faster than the car. A missile has that. That makes the missile already have the planes speed plus the acceleration it now gets from it's "rocker boots". The other reason is that your plane might be faster than the missile, but that is highly unlikely because the sidewinder travels at about 700m/s i think. Can you give us a teaser of what we can expect from 0.6.0 or possibly 0.5.1? And could you maybe make some other versions of your crittercrawler or some helicopter parts?
