ASSEMBLY:
1. Locate the bag marked “Aileron” and “Flap”. Install aileron and flap control horns and rods for
each side of the wing as shown. Ensure the servo horn is at 90 degrees to the wing when installing
the rod.
2. Install the horizontal tail to the fuselage as shown.

3. Locate the bag marked “Elevator”Install horizontal tail, control horns and rods with the supplied
bolts as shown. Ensure tail is firmly secured and aligned.
4. Locate the bag marked “Rudder” Install the control horns on the vertical tail. Connecting the pre
installed control rods to the outer hold of the control horn.

5. Mount the wing to the fuselage with the supplied bolts. Make sure to feed servo wires into
passage to fuselage compartment, ensuring no wires are pinched in the wingsaddle.
6. The final stage of assembly is to mount propeller. Slide prop onto motor shaft, engaging molded
hex detail on back of propeller to hex fitting on prop shaft. Tighten prop nut to shaft firmly by hand.
Note: It is recommended that you balance the prop and spinner before
installing for optimum performance and efficiency.

Check control surfaces for proper movement with applicable stick input.A reversed control could lead
to loss of control and damage to the model.
4. Linear power delivery is important to optimal flight performance. Calibrate the ESC using the
instructions below when switching to a new transmiter.
A. Switch ON the transmitter and move throttle stick to 100%. (Full Throttle)
B. Connect flight battery pack and wait about 2 seconds.
C. The ESC will emit a ‘beep-beep’ tone meaning the high point of the throttle range has been set.
D. After the tone is emitted, move the throttle stick back to low throttle. Youwill hear the regular
initialization beeps indicating the number of cells in the battery.
E. After the initialization tone from low throttle, regular throttle control is
available.

5. The center gravity (CG) for the T-28 Trojan is approximately 50-60mm from the leading edge of
the wing. Using the recommended 4S 14.8V 2200mah LiPo, the correct CG can be attained
quite easily due to the ample battery space. If using larger capacity batteries, you may need to
shift the battery backwards more to attain the correct CG.

leading edge of the wing at the root.
Measure with the model inverted.

reverse direction
1. Motor/esc connection error
1. Swap around any 2 of the 3
ESC/motor wire connections
Control surfaces
not moving with
stick input
1. The servo lead is connected
to Rx incorrectly.
2. The servo is damaged.
1. Make sure the servo leads
are connect properly.
