Great Planes T-Craft 20 Kit - GPMA0155 - Manual (Page 45)

The throws are measured at the widest part of the elevators,
rudder and ailerons. Adjust the position of the pushrods at
the servo horns and the nylon control horns to change the
amount of throw. You may also use the ATV's if your
transmitter has them.
Follow the battery charging procedures in your radio
instruction manual.You should always charge your transmitter
and receiver batteries the night before you go flying and at
other times as recommended by the radio manufacturer.
Carefully balance your propellers before flying. An
unbalanced prop is the single most significant cause of
vibration. Not only may the engine mounting screws vibrate
loose, possibly with disastrous effect, but vibration may also
damage your radio receiver and battery. Vibration may
cause your fuel to foam, which will, in turn, cause your
engine to run lean or quit.
We use a Top Flite Precision Magnetic Prop Balancer ™
(TOPQ5700) in the workshop and keep a Great Planes
Fingertip Balancer (GPMQ5000) in our flight box.
The best place to fly your T-Craft is at an AMA chartered
club field. Ask the AMA or your local hobby shop dealer if
there is a club in your area and join. Club fields are set up
for R/C flying and that makes your outing safer and more
enjoyable. The AMA also can tell you the name of a club in
your area. We recommend that you join AMA and a local
club so you can have a save place to fly and have insurance
to cover you in case of a flying accident. The AMA address
and telephone number are in the front of this manual.

At this time check all connections including servo horn
screws, clevises, servo cords and extensions. Make sure
you have installed the nylon retainer on the Screw-Lock
Pushrod Connector on the throttle pushrod and the
silicone retainers on all the clevises.
PREFLIGHT
We recommend the following control surface throws:
High rate Low rate
Elevator: 1/2" up 5/16" up
1/2" down 5/16" down
Rudder: 1" right 1/2" right
1" left 1/2" left
Ailerons: 5/8" up 7/16" up
5/8" down 7/16" down
Note: If your radio does not have dual rates, we
recommend setting the throws between the low and high
rate amount.
Note: The balance and control throws for the T-Craft have
been extensively tested. This chart indicates the settings
at which the T-Craft flies best. Please set up your model
to the specifications listed above. If, after you become
comfortable with your T-Craft, you would like to adjust the
throws to suit your tastes, that's fine. Too much throw can
make the plane harder to handle or force it into a stall or
snap roll, so remember, “more is not always better.”
