The airframe of the Seagull Models Challenger Super Sportster RC plane is conventionally built using balsa, plywood to make it stronger than the average ARF, yet the design allows the aeroplane to be kept light. You will find that most of the work has been done for you already. The motor mount has been fitted and the hinges are pre-installed. Professionally covered with Ultracote, this is a model that will last, and provide years of enjoyment. Suitable for 46 size 2-stroke engines or 600-800 watt electric power (5-6S)
