US aircore ??
I have flown a few of these planes for club members. The Colt flies very well. It will be a much better flying plane than the Durastick. The color doesn't last very well with glow fuel. Vinyl graphic film will take care of that though. You won't have to work so hard to keep it in the air and it is very durable. It would work well for an aerobatic trainer.
