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 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.
