The ideal C.G. position is 83mm (3.25in.) behind the leading edge measured at where the wing meets the fuselage. In order to obtain the C.G. specified, add weight to the fuselage or move the battery position. Check the C.G. before flying. If you are converting this model to electric, please move the C.G. forward 10% of current C.G. distance from leading edge to compensate for weight of fuel. 83mm 3.25 in C.G. http://www.thewingsmaker.com/instructionManuals.php Warning! Important Safety Precautions # First time flyer should never fly by himself / herself. Assistance from experienced flyer is absolutely necessary. # Pre-flight adjustment must be done before flying, it is very dangerous to fly a badly pre-adjusted aircraft. # FAIRCHILD PT-26 40 is specially designed to be powered by 2 C 0.40 or 4 C 0.52 engine, using a more powerful engine does not mean better performance. In fact, over powered engine may cause structural damage and injuries. # Make sure the air field is spacious, never fly the plane too close to people and never get too close to a running propeller. # If you find wrinkles on the covering as a result of weather changes, you can use hot iron to remove the wrinkles. Please begin with lower temperature setting and gradually raise the temperature until the wrinkles are gone. Too hot an iron may damage the covering. Don't use hot iron near the seams or edges, hot iron will melt the glue and shrink the covering at the same time, causing the seams to pull away. # Check and re-tighten up all factory assembled screws, use thread locker if necessary.
