Is the ultrasport really a refined kaos? I understood that one of the P-51 kits had a wing that was essentially an ultrasport wing, and was supposed to be a great flyer.
That's the secret. The Ultra Sport has the same wing as a Kaos. The difference is that the Ultra Sport has a turtledeck and a bit more refined fuselage that gives it the knife edge performance the Kaos doesn't have.
