NOTE FROM THE DESIGNER

The Viper is a radio controlled profile style design parkjet based off of the Viper from the series Battlestar Galactica.  It's very stable and flies very well.  The Center of Gravity location is right at the back of the canopy, or a little in front of that location.  This model is very sensitive to having the correct CoG, as it will stall at low speeds with the wrong CoG.  The plans don't have a slot for a carbon rod, but the builder may want to consider adding one in the wings.  Keep the plane light and it will fly better.  Delta Wing mixing required.
