Firmware Updates

In the event of a firmware update notice from IFT..

STEP	ACTION
1	Locate the USB-C port underneath the battery plate. Use this port to connect your PC to the drone.
2	Download the firmware file provided to you by IFT customer support.
3	Open the file and select run and select "Run in Terminal".
4	After a few moments, the script will erase and the message "Upload Complete" will display. At this time, it is safe to disconnect your PC from your drone.

Every 10 Flight Hours

Due to harmonic vibrations in flight, it is recommended to check critical screws every 10 flight hours. Use the diagrams below as a reference for screw locations.

If a screw is loose, remove it and apply Loctite Red 271 before reinstalling and tightening.

Every 100 Flight Hours: Motor Inspection

Over time, motor bearings are exposed to wear and damage.

To inspect motor bearings for anomalies:

STEP	ACTION	RESPONSE
1	Give each motor a spin by hand	They should all coast to a stop and make the same sound
2	Firmly grab each motor by the propeller hub or rotating portion of the motor and wiggle side to side	There should be zero or minimal play and all should feel similar

Every 200 Flight Hours: Propeller Replacements

To ensure the continued success of your vehicle, replace the propellers every 200 flight hours.

The screws can be removed and installed using an 2.5mm hex driver.

Removing Props	Installing Props
The propellers are attached to the motor with 4 mounting screws and a locating pin.	Use Loctite Blue 242 on screws Torque screws to 1.2N

Every 3 Months: Battery Maintenance

• Always check your battery's individual cell voltage before and after usage.

• While storing your battery for an extended period of time, check the voltage of each individual cell at least once every three months using either a LiPo checker or charger.

• When storing your battery, ensure each cell is between 3.85V to 3.90V.

• If the cell(s) fall below 3.7V or have more than 0.05V/50mV(6S), 0.1V/100mV(12S) difference, please complete a charge/discharge cycle: At 1C of lower rate, charge the battery to 4.2V/cell, then discharge down to 3.55V/Cell, and finally back to 3.85-3.9V/cell for storage.

NOTE: Batteries, especially those with a BMS board, will naturally self-discharge over time. Adhere to the following tips to prolong the life of your battery:

1	Always check your battery's individual cell voltage before and after usage.
2	While storing your battery for an extended period of time, check the voltage of each individual cell at least once every three months using either a LiPo checker or charger.
3	When storing your battery, ensure each cell is between 3.85V to 3.90V.
4	If the cell(s) fall below 3.7V or have more than 0.05V/50mV(6S), 0.1V/100mV(12S) difference, please complete a Charge/Discharge Cycle: At 1C a lower rate, charge the battery to 4.2V/cell, then discharge down to 3.55/Cell, and finally back to 3.85-3.9V/cell for storage.

Every 6 Months/600 Flight Hours: Return to IFT for Inspection
