Hirobo Helicopters The Shuttle Challenge truly is the easiest helicopter to fly! Introducing the Shuttle Challenge - The ultimate training helicopter! It's what the sport of R/C helicopters has been waiting for! Only Hirobo, the world's largest manufacturer of model helicopters and the world famous Shuttle series could usher in a new era for R/C model helicopters by introducing the easy to fly Shuttle Challenge. We tested it and found the Shuttle Challenge is truly the easiest helicopter to fly! At the 1998 Hirobo Cup, novices and experts alike flew the Shuttle Challenge for three days straight without a single mishap. Spectators and pilots as young as 5 years old and up took the sticks and succeeded! The Challenge is fundamentally a Shuttle ZTS, but has redesigned components to make it more stable. Created with the novice in mind, it features a newly designed Rotor Head and special Training Gear. The Rotor Head uses new geometry in the mixing arm, see-saw area as well as new pitch arms to produce the soft controls and higher stability every new pilot benefit from. The training gear is fully articulated and guides the Challenge while landing and taking off. The Carbon Fiber Training Legs absorb shock and impact as well as prevent tipping. They automatically adjust the helicopter's position from a flattened stance to a fully extended position while in higher attitude of three feet high or greater. Other features that make the Challenge so remarkable are that all drive components are Ball Bearinged for durability and precision. Plus a Top Shaft Start System is included and is part of what makes the Shuttle Challenge a great value. As the beginner flyer becomes a more experienced pilot, the Challenge can be upgraded to a Shuttle ZXX or even up to the awesome Shuttle RG. The Shuttle Challenge is available as a kit or ARF. Included in the kit are factory Finished Blades, Starting Shaft, Landing Gear Skids to upgrade the training gear, Main Blades support and Pitch Gauge. With a kit this extensive you'll want to start flying today. At Last a Helicopter That Anyone Can Fly!
