Rugged and Efficient Starship is built with a 100% Kevlar fuselage. Strong as a baseball bat, there are no stronger fuses in the industry. Rocks beware! Solid Core Wings: Hollow molded might be more profitable, but nothing beats the abuse a solid core wing can take. High Load 60 Cores: We clipped the top of a tree and the plane turned into a high speed frisbee into the ground. Compression failure of the top skin but the wing was still perfectly straight and supported a very firm load test, so we kept flying... for the rest of last season! Efficiency: Highest aspect ratio wings in this size model. Laminar flow airfoils. Skate Ramps: Strong verticals combined with good low speed control means these planes can turn and burn in the tightest of spots. Don't let the 90" span fool you! We fly these planes in the smallest of places.
