hi just would like someone to help me. this is my first modeling kit i bought and im really excited cause i used to build gundams but ive grown to love cars and how cool it would be to build one. but yeah on to the question. uhh during the first few steps in the manual does anyone find it very hard to keep the parts together??? when building the engine. every time i assemble it i cant never keep it in one piece it alwys falls apart
