Wheh you hbuild your indoor airplane, always remember to keep the model as light as possible. The weight of an indoor airplane is very critical and is directly proportional to the flight characteristics of that model. In addition to keeping the model light, you can improve your indoor flying by:rnFinding the proper center of gravity to suit your flight needs. Begin by moving your battery forward or backward if the airplane is tail heavy or nose heavy. Also, try tampering with the height of the battery to minimize pitch and roll coupling when in knife-edge. As a general rule of thumb, keep the battery fairly centrally located (in height) on the fuselage so that the airplane is "neutral" in rolling maneuvers.
