Great Planes U-Can-Do 3D 60 ARF - GPMA1270 - Manual (Page 21)

1. Use scissors or a sharp hobby knife to cut the decals from
the sheet.
2. Be certain the model is clean and free from oily
fingerprints and dust. Prepare a dishpan or small bucket with
a mixture of liquid dish soap and warm water–about one
teaspoon of soap per gallon of water. Submerse the decal in
the soap and water and peel off the paper backing. Note:
Even though the decals have a “sticky-back” and are not the
water transfer type, submersing them in soap & water allows
accurate positioning and reduces air bubbles underneath.
3. Position decal on the model where desired. Holding the
decal down, use a paper towel to wipe most of the water away.
4. Use a piece of soft balsa or something similar to
squeegee remaining water from under the decal. Apply the
rest of the decals the same way.

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.
Use a ruler to accurately measure and set the control throw of
each control surface as indicated in the chart that follows. If your
radio does not have dual rates, we recommend setting the
throws at the low rate settings. NOTE: The throws are measured
at the widest part of the elevators, rudder and ailerons.
More than any other factor, the C.G. (balance point) can
have the greatest effect on how a model flies and may
determine whether or not your first flight will be successful.
If you value this model and wish to enjoy it for many flights,
DO NOT OVERLOOK THIS IMPORTANT PROCEDURE.
A model that is not properly balanced will be unstable and
possibly unflyable.
Balance the Model (C.G.)
IMPORTANT: The U-CAN-DO 3D has been extensively
flown and tested to arrive at the throws at which it flies best.
Flying your model at these throws will provide you with the
greatest chance for successful first flights. If, after you have
become accustomed to the way the U-CAN-DO 3D flies, you
would like to change the throws to suit your taste, that is fine.
However, too much control throw could make the model
difficult to control, so remember, “more is not always better.”
We recommend the following control surface throws:
High Rate Low Rate
ELEVATOR: 1-1/8" [28mm] up 3/4" [19mm] up
1-1/8" [28mm] down 3/4" [19mm] down
RUDDER: 2-1/4" [57mm] right 1-1/4" [31mm] right
2-1/4" [57mm] left 1-1/4" [31mm] left
AILERONS: 1-3/8" [35mm] up 7/8" [22mm] up
1-3/8" [35mm] down 7/8" [22mm] down
3D Control Throws
NOTE: The 3D control throws are only meant to be used
for extreme aerobatics. These are not meant for normal
flying. Be confident using your dual rate switches before
utilizing these rates.
ELEVATOR: 3" [75mm] up
3" [75mm] down
RUDDER: 4" [100mm] right
4" [100mm] left
AILERONS: 2-1/8" [55mm] up
2-1/8" [55mm] down
