GET THE MODEL READY TO FLY
INSTALL THE PROPELLER
❏
1. Carefully balance the propeller and any spare
propellers. An unbalanced propeller can be the single
most signifi cant cause of vibration that can damage
the model. Not only will engine mounting bolts loosen,
possibly with disastrous effect, but vibration may also
damage the receiver and receiver batteries. Vibration
can also cause the fuel to foam, which will, in turn,
cause the engine to run hot and quit.
We use a Top Flite Precision Magnetic Prop Balancer
(TOPQ5700) in the workshop and keep a Great
Planes Fingertip Prop Balancer (GPMQ5000) in our
fl ight box.
❏
2. The included aluminum prop hub was designed
to be used with the DA-50 or the Fuji-Imvac BT-43EI-2
gas engines. Bolt the include prop hub in front of the
propeller in place of the prop washer.
❏
3. Install the prop hub cone on the engine using
a M5 x 50mm socket head cap screw. Use a drop of
threadlocker on the threads.
BALANCE THE MODEL LATERALLY
❏
1. With the wing level, have an assistant help you
lift the model by the engine propeller shaft and the
bottom of the fuse under the TE of the fi n. Do this
several times.
❏
2. If one wing always drops when you lift the model,
it means that side is heavy. Balance the airplane by
adding weight to the other wing tip. An airplane that
has been laterally balanced will track better in
loops and other maneuvers.
CHECK THE CONTROL DIRECTIONS
❏
1. Turn on the transmitter and receiver and center
the trims. If necessary, remove the servo arms from
the servos and reposition them so they are centered.
Reinstall the screws that hold on the servo arms.
❏
2. With the transmitter and receiver still on, check
all the control surfaces to see if they are centered.
If necessary, adjust the clevises on the pushrods to
center the control surfaces.

3. Make certain that the control surfaces and
the carburetor respond in the correct direction as
shown in the diagram. If any of the controls respond
in the wrong direction, use the servo reversing in
the transmitter to reverse the servos connected to
those controls. Be certain the control surfaces have
remained centered. Adjust if necessary.
SET THE CONTROL THROWS
To ensure a successful fi rst fl ight, set up your
Giant P-47D ARF according to the control throws
specifi ed in this manual. The throws have been
determined through actual fl
ight testing and
accurate record-keeping, allowing the model to
perform in the manner in which it was intended. If,
after you have become accustomed to the way the
Giant P-47D ARF fl ies, you would like to change
the throws to suit your taste, that is fi ne. However,
too much control throw could make the model too
responsive and diffi cult to control, so remember,
“more is not always better.”
