4. Test fit the prop saver against the hub of the included

propeller. The proper fitting side faces forward when installed.
Slide the prop saver onto the gearbox output shaft. Make sure
that the screws seat down into the two flat spots on the shaft.
Secure the screws with threadlocking compound.

5. Install the cowl onto the nose. Secure it with 4 small

drops of hot glue. This will make it easy to remove if needed
for motor maintenance or replacement.

6. Cut off a 1" piece of the hook and loop material (used

to install the receiver in step 8). Install the remaining hook
side of the hook and loop fastener into the battery
compartment. Stick the remaining loop side onto the battery
pack. The pack will sit on its side in the fuselage.

7. Secure the propeller to the prop saver using one of the

included o-rings.

8. Install the receiver behind the battery using hook and

loop fastener. Run the antenna out the back of the zippered
fuselage opening. Use a pin to puncture two holes 1/2"
[12mm] apart in the vertical fin. Stick the receiver antenna
through the holes as shown.

9. The ESC can be tucked into the front of the fuselage

on either side of the battery.

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.

3. Make certain that the control surfaces and the motor

respond in the correct direction as shown in the diagram. If any
