In order for your Alpha 40 RTF 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 Alpha 40 RTF is to mark
the location for the balance point. The ideal balance point
for the Alpha RTF is 2

–3 inches (70–76mm) back from
the leading edge against the fuselage. If your plane is only
slightly out of balance, try placing the balancing stand
towards the nose or tail by 1/8-inch (3mm) and recheck
the balance. If it looks good and sits level, then you’re
good to go.
Nose Heavy – Add Weight to Tail
Lifting the Model and Observations
Make sure the Alpha RTF 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.
