Set the Control Throws
To ensure a successful fi rst fl ight, fl y your Escapade set up
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. They will provide you with the best chance
for success and an enjoyable fi rst fl ight 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 designed. DO NOT OVERLOOK
THESE IMPORTANT PROCEDURES. A model that is not
properly set up may be unstable and possibly unfl yable.
The throws are also provided in degrees should you have an
instrument capable of measuring the throws in that way.
Note: The throws are measured at the widest part of the
elevators and rudder.
Using the method for measuring the throws illustrated as
follows, adjust the locations of the pushrods in the control
horns and/or in the servo arms (or use the programming
in your radio) to set the control throws according to the
measurements provided in the Control Throws Chart.
❏
A. Use a small box or something similar to prop up the
fuselage until the wings and horizontal stab are level.
❏
B. Take the reading of the surface you are measuring at the
widest part of the control surface at the trailing edge.
(MOVE THE RULER FORWARD)
❏
C. Move the control surface and move your ruler forward.
Read the measurement to get the throw.

Note the effect pushrod location has on the throws. If using
programming in your transmitter to adjust the throws, note that
the pushrods should be connected so that with the ATVs (or
endpoints) at or near 100%, you can get the throws specifi ed.
In other words, with the ATVs at 100%, FIRST change the
pushrod location to get the correct throws as close as possible,
THEN use the programming for fi ne-tuning.
