In order for your F-22 Raptor PTS to fly correctly, you will
need to check the balance of the plane with the fuel tank
empty. This is done by supporting the aircraft either using
your fingers or by using a balancing stand. Not checking
the balance can result in an aircraft that is difficult to fly,
which can lead to the possibility of crashing your model.
Marking the Balance Point
The first step in balancing your F-22 Raptor PTS is to
mark the location for the balance point. The ideal balance
point for the F-22 PTS is 6 inches (152mm) back from the
leading edge against the fuselage, but it can vary up to
1/4-inch (6mm) in front or behind the 6-inch mark without
causing any problems. If your plane is only slightly out of
balance, try placing the balancing stand towards the nose
or tail by this 1/4-inch (6mm) and recheck the balance. If
it looks good and sits level, then you’re good to go!

Lifting the Model and Observations
Make sure the F-22 Raptor PTS is balanced using either
your fingers or a balancing stand. Place or lift the airplane
so it is supported at the marks made in the previous step.
The plane will rest level when balanced correctly. If not,
weights must be added to correct any balancing problems.
