# 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.

## Check Motors

Over time, motor bearings are exposed to wear and damage.&#x20;

### **To inspect motor bearings for anomalies:**

<table><thead><tr><th width="115" align="center">STEP</th><th>ACTION</th><th>RESPONSE</th></tr></thead><tbody><tr><td align="center">1</td><td>Give each motor a spin by hand</td><td>They should all coast to a stop and make the same sound</td></tr><tr><td align="center">2</td><td>Firmly grab each motor by the propeller hub or rotating portion of the motor and wiggle side to side </td><td>There should be zero or minimal play and all should feel similar</td></tr></tbody></table>

## Propeller Replacements&#x20;

*The screws can be removed and installed using an **2.5mm hex driver**.* &#x20;

## 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.&#x20;
