No, the models are perfect. Almost everything in it is great but the flight system could use some tweaks and the UI is default human. All it needs is a make over. Better preview screen, custom icons, remove selection circles, and a few adjustments to the flight system. The adjustments might be a speed control or a multiboard that reads height, speed, etc. Take your time. Check it out after exams. It could be a quick project with big interest. I think it would be fun and satisfying.
I think I will go back and bring choplifter to life too. Do you have the most recent copy? I looked and all of mine were bugged except one that was a bit older. The flight system was fine but the missions weren't finished.
