Model types


Indoor models are built light and fly slower than ones set up to stand the rigors of outdoor flying, including wind.  They are adjusted to climb to the height of the ceiling at the flying site.  Sites are classified by height.  Memorial Hall in Racine and the Hangar at Rantoul are Category II sites with higher ceilings than school gyms.


Outdoor models are more robust and fly faster than indoor ones.  The height they reach during the initial power burst from their motors is only limited by their power to weight ratio. The wind may carry them quite a distance.  Many Bong Eagles members mount small radio transmitters on these planes to aid finding them when they land.


Planes built according to the rules of the Flying Aces Club may be set up to fly indoors or out.  The Flying Aces Club (an AMA Special Interest Group) promotes building and flying Stick and Tissue model aircraft similar to those designs published in the Flying Aces Magazine many years ago.  Most of the competition classes are for scale replica planes, and are judged for faithfulness for their prototype full scale planes.  The most rigorous judging is for “Rubber Scale”.  Designs considered “Dime Scale” are based on the simple kits of yore, and are built light with less attention to exact scale.  There is a sport class called “Embryo” where wing area is limited to 50 square inches and bonus seconds are awarded for flair items like wheel pants.
