Make two marks on the tape one 51/2-inches, one 6 1/4-inches back from the leadingedge of the wing. Repeat on the other side of thefuselage. These marks represent the limits of theC.G. range.Turn the aircraft upside down and support it frombetween the two marks. Slide the battery pack to aposition where the plane will balance level toslightly nose heavy. Mount the battery inside thefuselage at the determined location. Install the onoff switch in a convenient location per themanufactures instructions. Reinstall the wing andcheck the C.G. again.
