I belong to an RC club that gets to use an obsolete runway at the local airport as a flying field. The local SCCA club uses it too for their races every three months. I took the Viper over this morning and had to wring it out a bit. After several donuts and long wheel spinning slides I couldn't stop grinning. I'll go back one day this week when no one else is around and get some video. Did you know you can spin a Viper fast enough to really feel the G forces pushing you back? It's soooo much fun!!
