hi, i am a newbie in paper model. I am trying to build the Star wars X-wing paper model. I want to know no matter how much i try, the body of the plane dont seems to be parallel at all, it will not be noticed until you really get a close look to it. But i really want it to look perfect! As for the engine, it gives me an even bigger problem because you need to put a piece of paper into the cillinda shape engine, but i always failed to put that paper to where it belongs, and it looks so out of place. And the other project that i was building is a starcraft siege tank. it is working well until i encountered a major problem. The glue i am using is changing the color of the tank, and the paper dont always get into the shape i want.
