 This is the Great Planes Viper 500 ARF .25-.46 52" Airplane Kit. With a 2-stroke .25 and separated elevator/rudder control, the Viper 500 is a fun, everyday sport model. Use V-tail mixing and a larger engine, and it becomes a fiery, ultra-competitive "club racer"...and it's AMA-legal for Quickie 500 in 424 and 428 classes!
World-famous airfoil designer Dr. Michael Selig created the airfoil specifically for Quickie 500 racing. Great Planes adds performance-boosting "extras", including a perfectly formed engine mounting plate and to minimize drag, specially engineered wheels and mounting hardware and recessed wing hold down bolts.
