# Maintenance ## Recommended Maintenance Schedule for IF1200 These recommendations are based on flight with a typical payload in optimal flight conditions. Additional maintenance may be needed at the pilot's discretion.


Recommended Maintenance Activities	Pre-flight	25 Flight Hours	50 Flight Hours	3 Months
Inspect all moving components for wear/damage	X
Check propellers for damage	X
Dust all lenses	X
Check Battery Health	X
Inspect all visible screws and tighten if needed according to torque guidelines (contact customer support)		X
Clean motors with an air can		X
Enable Battery Storage Mode (if not in use)				X

## Check Motors 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

## Propeller Replacements *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. |

Propellors marked 26.2 x 8.5R are mounted in position 2, 4, and 5. (See diagram below).
Propellors marked 26.2 x 8.5L are mounted in position 1, 3, and 6. (See diagram below).
Use Loctite Blue 242 on screws
Torque screws to 1.2N

Standard HEXA X propellor positioning for hexcopters.

## Every 3 Months: Check Battery Cell Voltage * We recommend checking 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. {% hint style="info" %} 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: {% endhint %}

Steps to Prolong Battery Life
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.
