LATERAL BALANCE
!
After you have balanced a plane on the C.G. You
should laterally balance it. Doing this will help
the airplane track straighter.
5. Turn the airplane upside down. Attach one loop of
heavy string to the engine crankshaft and one to
the tail wheel wire. With the wings level, carefully
lift the airplane by the string. This may require
two people to make it easier.
6. If one side of the wing fall, that side is heavier
than the opposite. Add small amounts of lead
weight to the bottom side of the lighter wing
half's wing tip. Follow this procedure until the
wing stays level when you lift the airplane.
CONTROL THROWS
1. We highly recommend setting up a plane using
the control throws listed.
2. The control throws should be measured at the
widest point of each control surface.
3. Check to be sure the control surfaces move in the
correct directions.
