Doug, sorry for the poor photo quality but that is what you get when scanning a 35 year old photograph.

The color was a brilliant transparent blue epoxy made by leaching the dye out of Rit Dye using the K&B epoxy thinner and then putting the concentrated blue thinner in clear K&B epoxy and spraying it over a silver base coat. The bottom was left silver for high contrast in the rolls. Some days when the sun was right it flashed like a hooked marlin during the rolls.

The barn door ailerons should be just fine. Are you using two servos?
