With a 2-stroke .25 and separate elevator/rudder control, the Viper 500 is a fun, everyday sport model. But when equipped with a larger engine and V-tail mixing, it becomes an ultra-competitive club racer. With versatility like that, the Viper 500 will appeal to a wide range of modellers.
Assembles in as little as 6-8 hours.
The wood/foam wing is reinforced with carbon fiber, and arrives pre-covered in genuine Top Flite MonoKote film.
The bolt-on tail provides accurate alignment for fast assembly and can also be removed for easy transportation.
In addition to an airfoil created for quickly 500 racing by world-famous designer Dr. Michael Selig, the Viper 500 also features wheels and mounting hardware engineered specifically to minimize drag.
