c) Attach your ESC and confirm that the motor runs in the correct direction by connecting the ESC’s

throttle lead to your radio receiver’s throttle channel; switch ON your transmitter and set transmitter’s

throttle and throttle trim controls to minimum; with no propeller on the motor, switch ON your

transmitter and connect the ESC to the battery; after you hear a series of initialization sounds, slowly

raise the transmitter’s throttle to no more than 25% of maximum.

d) Carefully run the motor slowly and only for the few seconds necessary to observe its direction of

rotation. If the motor rotated in the clockwise (correct) direction as viewed from the rear of the

airplane, return the throttle to minimum, disconnect the ESC from the battery, switch OFF the

transmitter, and set your battery and transmitter aside. However, if the motor powered up in the

counterclockwise (wrong) direction, return the throttle control to minimum, disconnect the ESC from

the battery, swap either two of the three ESC-to-motor wires, and repeat the above procedure to

ensure the motor rotates in the correct direction.

3. Mains Landing Gear Assembly –

(NOTE: If you will use floats, replace this section with the detailed instructions included with the floats.)

a. Turn the fuselage up-side down. If necessary, spread the main landing gear assembly’s crossmember

wires to align with the precut slots located under the Mylar covering material as shown below.

(IMPORTANT: Do NOT cut away the covering over the slots; instead, leave the Mylar covering

material to be pressed into these slots to help keep the wood inside each slot from getting soaked with

any residual exhaust oil.)

b. Make a clean ‘slice’ in

the Mylar from side-

to-side over the mid-

line of each slot.

c. Position the landing

gear’s front and rear

crossmembers over

their slots to help

locate and poke ‘open’

the Mylar covering the

predrilled mounting

screw holes.

d. Press the landing

gear’s front and rear

crossmember wires

into their slots. Using

the supplied mounting

screws (#5), install the

four hold-down plates

(#4, two across each

cross-member).

e. Locate the wheel collars (#3) as shown and secure each mains wheel (#2) to its axle by tightening the set

screw in each wheel collar.

4. Tail Surfaces –

a. Test-fit the vertical stabilizer, rudder, horizontal stabilizer and two halves of the elevator.

(IMPORTANT: The elevator will REMAIN in two separate halves; one half will be installed on each

side of the vertical stabilizer – otherwise you will not be able to insert the horizontal stabilizer through

its slot at the end of the fuselage.)

b. Slide the horizontal stabilizer through the slot at the end of the fuselage. Center and align the horizontal

stab. at a right angle to the centerline of the fuselage, and secure it in place with thin CA adhesive.

c. Using the supplied CA hinges and thin CA, attach the two halves of elevator to the horizontal stabilizer.
