I go back and forth, from model cars, to armor, to ships, and then to RC boats, and then my RC car, and then my rockets, and then my trains. Its a vicious cycle. I fly rockets at least once a month, and I build and maintain my rockets as such. I work on models as I have time, so I may be working on my train layout, a car, a tank, and a ship, all at one time. I don't have time for burnout.
