Determining the flaperon's moment:
 Measuring the turn moment of the flaperon is done by setting it up on a special stand and
measuring the mass. The stand should hold the flaperon level and allow it to rotate on its
hinges freely.
 First place the flaperon on the stand, level it and place a scale under the end which is
closest to the fuselage. Our factory made flaperons typically have a reading of
approximately 600 – 700 grams. If you don't get this reading add or remove
counterbalances accordingly.
 Now assemble the flaperon to the wing using a decent amount of grease on the pins. Be
sure to use a magnet to get the washer and nut onto the end securing pin. Then tighten
