I set my GP extra 300 aside for 5 months, I did other things in the mean time, worked, eorked on my CJ-7 restoration, hung out with friends, but when I was forced to stay home, I picked it back up again. I managed to finish the plane off in 2 weeks, so just put it on the side and don't give yourself a deadline. If it seems like it's taking forever, your not going to enjoy any of it, and the same feeling might creep up on you durring the next build. Take your time and work on it when you get motivated.
