Estes Flying Model Rocket Kit Gryphon 7280 Built to protect, don’t underestimate the slim, yet stately design of the Gryphon. Standing 18 inches tall with a slender diameter measuring just over .5 inches, the sleek sports rocket is strong enough to support the six-inch wingspan of its stealthy cargo, a glider.Meeting all expectations set by its legendary name, the Gryphon model glider kit will be the “King of the Air”. The Gryphon itself can soar to the height of 700 feet on an A10-3T engine. Upon reaching apogee, a colorful streamer acts as a tracking and recovery device to show where the rocket will land. During that time, the Gryphon’s stealthy glider moves magically across the sky to serve as a protector to everything below and will also gracefully return to earth to be readied for another flight.Made from lightweight paper tubing and laser-cut balsa, the Gryphon is a great first step above a beginner rocket. In about two hours, plus painting time, rocketeers will build a rocket that will garner attention in both the air and when on display.Skill Level 2 IntermediateLength 18.0 in.Diameter Rocket : 0.54 in.Glider Wingspan : 6.00 in.Estimated Weight 0.60 ozEstimated Assembly Time 2 Hours (painting and glue drying time not included)Fin Materials Laser Cut WoodDecal Type WaterslideLaunch Rod Size 1/8"Recommended EnginesA3-4T, 1/2 A3-2T, A10-3TProjected Max Altitude 700 ft.Recovery System 12 in.
