Set the Control Throws

In addition to the C.G., the control throws have a major effect
on how the model fl ies and whether or not your fi rst fl ight will
be successful. Do not skip this important step and make sure
the throws are within the specifi ed range. If necessary, use
programming in your transmitter and/or change the locations
of the pushrods in the servo arms and/or control horns to
adjust the throw.
Use a box or something similar to prop up the fuselage so the
horizontal stabilizer will be level. Check and set the control
throws according to the measurements on the next page:
3. Glue strips of
balsa to the base
serving as tabs
for alignment – be
certain the tabs do
not interfere with
the fi t of the canopy
hatch to the fuselage.

Note: the throws are measured at the widest part of the
aileron, elevator and rudder.
These are the recommended control surface throws:
ELEVATOR
3/8 in. [10 mm] 11°
Up & Down
AILERONS
1/4 in. [6 mm ] 11°
Up & Down
RUDDER
1 in. [25 mm] 12°
Right & Left

Check the C.G.

Same as the control throws, the C.G. has a great effect on how
the model fl ies. If the C.G. is too far forward the model may
be too stable and unresponsive to control inputs. If the C.G.
is too far aft the model may be too responsive and instable.
1. The model should be completely ready to fl y with all
components installed (and an empty fuel tank if using a
glow engine).
2. If building the electric version, install the propeller and
spinner and install the motor battery.
