Prepare The Model For Flight; Set The Control Throws; Check The C.g - GREAT PLANES PT-19 Instruction Manual

4. Use your preferred glue to glue the windshields to the
canopy hatch. Of the viable choices (Zap Goo, CA or canopy
glue), canopy glue is most recommended because it dries
absolutely clear and is easier to clean up (before it dries). Use
tape where necessary to hold the windshields into position
until the glue dries.
5. Glue on the crash protector. Zap Goo is best here.
6. Apply the decals using images from the kit box cover
as a guide.

PREPARE THE MODEL FOR FLIGHT

Set the Control Throws

CAUTION: If you've installed a brushless motor, remove
the propeller while operating the radio to check the throws.
1. Prop up the fuselage so the stab will be level. Measure
and compare the throws to the recommended throws provided.
Note: the throws are measured at the widest part of the
elevator and rudder.
These are the recommended control surface throws:
ELEVATOR
Up & Down
RUDDER
Right & Left
AILERONS
Up & Down
2. If necessary, adjust the throws with the programming
in your transmitter and/or adjusting where the pushrods
connect to the servo arms and/or control horns.
3. Now would also be a good time to set your Fail Safe.
Set Fail Safe on the throttle channel so that, in the event
of loss of signal, the motor (or engine) cuts off. With the
propeller removed from brushless motors, test your fail safe
by advancing the throttle slightly (just enough to make the
motor turn) and turning off the transmitter. If the Fail Safe is
correctly set the motor will stop (or the carburetor will close
for glow engines).

Check the C.G.

1. The model should be completely ready to fl y with all
components installed (fuel tank empty if using a glow engine).
70mm

The recommended C.G. is 2-3/4"– 3-3/4"
[ 70 mm – 95 mm] back from the leading edge
of the wing at the fuselage sides.
2. Use a Great Planes C.G. Machine to balance the model
according to the measurements specifi ed, or mark the balance
range on the top of the wings and lift it upside-down with your
