Post-Flight Inspection and Maintenance Checklist
√
Cleaning
Make sure the battery is not connected before cleaning. Remove dust and debris with a soft brush or a dry,
lint-free cloth.
Motors
Replace the motor when the model will not fly steady or veers off when doing a climb out.
Wiring
Make sure the wiring does not block moving parts. Replace damaged wiring and loose connectors.
Fasteners
Make sure there are no loose screws, other fasteners or connectors. Do not over-tighten metal screws in plastic
parts. Tighten screws so the parts are mated together, then turn the screw only 1/8th of a turn more. Do not use
threadlock on or near plastic parts.
Propellers
Make sure there is no damage to the propellers or other parts that move at high speed. Damage to these parts
includes cracks, burrs, chips or scratches. Replace damaged parts before flying.
WARNING:
Remove the propellers from the motors prior to performing any troubleshooting or maintenance. Failure to
do so may cause serious injury if the motors start unexpetedly.
Takeoff
When you are prepared to fly, start the motors by activating the motor arm switch (switch H), as programmed in the
transmitter setup section. Increase the throttle until the model is approximately 2 ft. (600mm) off the ground and check
the trim so the model flies as desired. Once the trim is adjusted, begin flying the model.
Flight times for the included battery will vary according to how aggressively the throttle is used.
Low Voltage Cutoff (LVC)
LVC decreases the power to the motors when the battery voltage gets low. When the motor power decreases, land the
aircraft immediately and recharge the flight battery.
LVC does not prevent the battery from over-discharge during storage.
NOTICE:
Repeated flying to LVC will damage the battery.
Landing
To land, slowly decrease the throttle while in a low-level hover. After landing, stop the motors by changing the motor arm
switch to the off position; disconnect and remove the battery from the aircraft after use to prevent over discharge. During
storage, make sure the battery charge does not fall below 3V per cell.
Flying the Scimitar LRX Quadcopter
• In angle mode (
switch position 0
), the quadcopter will self-level and has a bank angle limit of approximately 60 degrees.
• In air mode (
switch position 1
), the quadcopter will not self-level and does not have a bank angle limit. At low throttle, the
flight controller will continue to stabilize the quadcopter to hold whatever attitude was last commanded. This mode is use-
ful for flying smooth aerobatic maneuvers at both high and low throttle settings.
• In acro mode (
switch position 2
), the quadcopter will not self-level and does not have a bank angle limit. At low throttle, the
flight controller will not stabilize the quadcopter. The pilot must actively control the quadcopter to maintain a desired at-
titude. This mode is most preferred when immediate changes in altitude are desired, such as in racing. Use rates and expo
to tune the performance according to your flying style.
