RE: What are some Things to remember when using a kit/planes
Don't build when you're tired.
Don't build when you're in a hurry.
Don't build to a deadline.
If you make a mistake and get frustrated: STOP, go away for a fews hours, then come back to it.
If you make a "wet" mistake (spilled paint, glue, etc.), clean it up just enough so you can: STOP, go away for a fews hours, then come back to it.
Have fun!
