Bring the battlefield legend to your launch pad with the MadCow Little John - a striking, single-stage sport scale rocket inspired by the iconic Cold War artillery round. With its stout 4-inch airframe and over 47 inches of presence on the pad, the Little John commands attention, whether you're prepping for a club launch or adding to your scale collection. Precision-cut plywood fins and robust construction deliver durability, while the classic profile offers a satisfying build experience for intermediate and advanced rocketeers. Designed for high-thrust power, the Little John flies on a single Aerotech I245, pushing this compact brute to over 1,700 feet with a fast, stable boost. Recovery is handled by a large parachute, ensuring gentle landings and quick turnarounds for multiple flights in a launch day. The broad body and scale details make for a rewarding paint and finishing project - perfect for those who love to blend craftsmanship with performance. Ideal for sport fliers, NAR events, or anyone looking to capture the spirit of military rocketry in a reliable, high-performance package. The MadCow Little John brings rugged scale realism and big-flight excitement to your rocket fleet - ready to deploy, ready to impress.
