Great Planes Pete 'n Poke 40 Kit - GPMA0493 - Manual (Page 37)

Use a Great Planes AccuThrow (or a ruler) to accurately
measure and set the control throw of each control surface as
indicated in the chart that follows. If your radio does not have
dual rates, we recommend setting the throws at the high rate
settings.
Note: The throws are measured at the widest part of the
elevators, rudder and ailerons.
At this stage the model should be in ready-to-fly condition
with all of the systems in place including the engine,
propeller, spinner, landing gear, wheels, covering and paint,
and the radio system.
❏
1. Use a felt-tip pen or 1/8"-wide tape to accurately mark
the C.G. on the bottom of the wing on both sides of the main
wing struts. The C.G. is located 3-7/8" [98mm] back from the
leading edge of the wing.
❏
2. With the wing attached to the fuselage, all parts of the
model installed (ready to fly) and an empty fuel tank, place
the model on a Great Planes CG Machine, or lift it at the
balance point you marked.
This is where your model should balance for your first flights.
Later, you may wish to experiment by shifting the C.G. up to
5/8" [16mm] forward or 5/8" [16mm] back to change the flying
characteristics. Moving the C.G. forward may improve the
smoothness and stability, but it may then require more speed
for takeoff and make it more difficult to slow for landing.
Moving the C.G. aft makes the model more maneuverable,
but could also cause it to become difficult to control. In any
case, start at the location we recommend and do not at any
time balance your model outside the recommended range.
More than any other factor, the C.G. (balance point) can have
the greatest effect on how a model flies, and may determine
whether or not your first flight will be successful. If you value
this model and wish to enjoy it for many flights, DO NOT
OVERLOOK THIS IMPORTANT PROCEDURE. A model
that is not properly balanced will be unstable and possibly
unflyable.
Balance the Model (C.G.)
IMPORTANT: The Pete ‘n Poke has been extensively flown
and tested to arrive at the throws at which it flies best. Flying
your model at these throws will provide you with the greatest
chance for successful first flights. If, after you have become
accustomed to the way the Pete ‘n Poke flies, you would like
to change the throws to suit your taste, that is fine. However,
too much control throw could make the model difficult to
control, so remember, “more is not always better.”
These are the recommend control surface throws:
High Rate Low Rate
ELEVATOR: 1-1/2" [38mm] up 3/4" [19mm] up
1-1/2" [38mm] down 3/4" [19mm] down
RUDDER: 1-1/2" [38mm] right 1" [25mm] right
1-1/2" [38mm] left 1" [25mm] left
AILERONS: 1" [25mm] up 3/4" [19mm] up
1" [25mm] down 3/4" [19mm] down
