Post Flight Checklist
Disconnect the flight battery from the ESC.
Power OFF the transmitter.
Remove the flight battery from the aircraft.
Recharge the flight battery.
Maintenance
WARNING: Do not perform this or any other equipment maintenance with the propeller installed on the aircraft.
Serious injury or property damage could result from the motor starting inadvertently.
Removing the Top of the Fuselage
To access the inside of the fuselage:
1. Remove the two screws holding the wing and slide the
wing out of the fuselage.
2. Use a fresh hobby knife to cut the tape holding the top
and bottom of the fuselage together.
Replacing the Propeller
WARNING: The motor will become hot during normal
use. Do not touch the motor until it has cooled.
To remove/replace the propeller:
1. Use needle-nose pliers or hemostats to grip the
propeller shaft to keep it from turning.
2. Spin the propeller counterclockwise to remove the old
propeller.
3. Thread the new propeller and spinner clockwise onto
the propeller shaft until snug. Do not overtighten the
propeller on the shaft.
Replacing the Propeller Shaft
WARNING: The motor will become hot during normal
use. Do not touch the motor until it has cooled.
IMPORTANT: The rear of the propeller shaft and nylon
nut are reverse-threaded.
To replace the propeller shaft:
1. Gently grasp the white nylon nut located at the back of
the propeller shaft using needle-nose pliers or hemostats.
2. While holding the nylon nut, rotate the spur gear
clockwise. The prop shaft will thread out of the nut.
3. Gently pull on the spur gear to slide the propeller shaft
out of the gearbox.
4. Thread the propeller and spinner onto the new
propeller shaft by holding the spur gear and turning
the prop clockwise.
5. Slide the new propeller shaft into the gearbox.
6. With needle-nose pliers, place the nylon nut on the
back of the propeller shaft. Spin the propeller and
spur gear counterclockwise to thread the nylon nut
onto the propeller shaft. Do not overtighten the nut,
as excessive wear on the motor and gears, as well as
poor performance will result.

Repair or replace all damaged parts.
Store the flight battery apart from the aircraft and monitor
