RE: TF Spitfire build
Your doing great so far. Keep the tail light, Light, LIGHT! I finished mine this year and it came in close to 11lbs. I fiberglassed and doped mine. It flys at that wieght, but it's not that pleasent. I also used CJ retracts and flaps. Powered mine with a Laser 4 stroke.
Good luck and have fun!!! [&:]
