Technical Specs
This is the Great Planes Viper 500 .25-.46 RTC (Ready-to-Cover) Sport/Racing Airplane. This version requires fiberglassing the wing and fuselage for safety. If you’re not experienced with fiberglassing, seek help from an experienced modeler. This airplane is recommended for intermediate flyers who have mastered a trainer and some sport models.

  • Pre-bent aluminum landing gear
  • Two low-drag nylon wheels, 2.5" (61mm) diameter

  • Warranty (through the manufacturer): Great Planes Model Manufacturing Company guarantees this kit to be free from defects in both materials and workmanship at date of purchase

With a 2-stroke .25 and separated elevator/rudder control, the Great Planes Viper 500 is a fun, everyday sport model. Use the 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 such performance-boosting "extras" as a perfectly formed engine mounting plate and—to minimize drag—specially engineered wheels and mounting hardware and recessed wing holddown bolts.
