The only thing about black on a airplane, sometimes they do not show up too good in the air. I myself like yellow and white with black pin stripes. On how much to reinforce....you do not add so much weight it ends up being a flying brick. Most airplanes fly much better "on the wing" instead of brute power and too much weight. Right Guys????? Capt,n P.S. Keep asking questions Mike...thats how you learn!
