Set The Control Throws; Balance Your Model (C.g.) - GREAT PLANES Performance Reactor Instruction Manual

Set the Control Throws

To ensure a successful fi rst fl ight, fl y your Reactor set
up only according to the C.G. and control surface throws
specifi ed in this manual. The throws and C.G. are not
arbitrary, but have been determined through extensive
testing and accurate record-keeping. This provides you
with the best chance for success and enjoyable fi rst fl ights
that should be surprise-free. Additionally, the throws and
C.G. shown are true, real data which will allow the model to
perform in the manner in which it was intended when fl own
by a pilot of the skill level for which it was intended. DO
NOT OVERLOOK THESE IMPORTANT PROCEDURES.
A model that is not properly setup may be unstable and
possibly unfl yable.
Use a ruler, an inclinometer, or a protractor 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 setting.
Note: The throws are measured at the widest part of the
elevators, rudder and ailerons.
These are the recommended control surface throws:

Balance Your Model (C.G.)

❏
1. Using a black felt-tipped pen, make a mark on the
bottom of each wing that is 7" [178mm] from the LE of the
root wing rib. This is the ideal balance point and this is where
your plane should balance for the fi rst few fl ights. If you wish
to experiment with the C.G., you may do so after you have
become comfortable with the plane. The forward C.G. limit
is 6.5" [165mm] from the LE of the root rib. The aft limit is
8" [203mm] from the LE of the root rib.
