4. Kuweka

Follow these steps to prepare your Mobula7 drone for its first flight.

4.1 Muunganisho wa Betri

Ensure the drone's power switch (if present) is in the OFF position.
Connect a fully charged 1S LiPo battery (450mAh, 550mAh, or 650mAh recommended) to the drone's battery connector. Ensure correct polarity.
Secure the battery in the designated battery tray or strap.

4.2 ExpressLRS Receiver Binding

The Mobula7 features a built-in SPI ExpressLRS 2.4GHz receiver. To bind it with your ExpressLRS compatible radio transmitter:

Power on the Mobula7 drone by connecting the battery. The receiver's LED should start flashing slowly.
Power cycle the drone three times rapidly (connect battery, disconnect, connect, disconnect, connect). After the third connection, the receiver LED should flash rapidly, indicating it is in binding mode.
On your ExpressLRS compatible radio transmitter, navigate to the ExpressLRS LUA script or menu and select the 'BIND' option.
Once bound, the receiver LED on the drone will turn solid, indicating a successful connection.
If binding fails, ensure your transmitter's ExpressLRS firmware version is compatible with the drone's receiver (v3.0 or newer recommended).

4.3 Betaflight Configuration (Advanced Users)

The drone comes pre-configured with Betaflight firmware CRAZYBEEF4SX1280 4.5.1. For advanced settings or troubleshooting, you can connect to Betaflight Configurator:

Download and install the latest Betaflight Configurator software on your computer.
Connect the drone to your computer using a USB-C cable.
Open Betaflight Configurator and click 'Connect'.
You can now adjust PID settings, rates, OSD elements, and other advanced parameters. Tahadhari: Modifying settings without proper knowledge can lead to unstable flight or damage.

Confirm your radio transmitter is powered on and bound to the drone.
Perform a range check in a safe area before flying.

5.2 Kuweka silaha na kupokonya silaha

The drone's motors will not spin until it is armed. Arming and disarming procedures are typically configured in Betaflight:

Kuweka silaha: Move the arming switch on your transmitter to the designated arm position. The motors will typically spin slowly, indicating readiness for flight.
Kupokonya silaha: Move the arming switch back to the disarm position. The motors will stop spinning. In an emergency, you can also disarm by moving the throttle to zero and yawing hard left or right (check your Betaflight configuration for specific emergency disarm gestures).

5.3 Vidhibiti vya Msingi vya Ndege

Familiarize yourself with standard quadcopter controls:

Kuteleza: Controls altitude (left stick up/down for Mode 2).
Mwayo: Rotates the drone horizontally (left stick left/right for Mode 2).
Kipaza sauti: Tilts the drone forward/backward (right stick up/down for Mode 2).
unaendelea: Tilts the drone left/right (right stick left/right for Mode 2).

5.4 HDZero VTX Operation

The integrated HDZero VTX transmits video to your HDZero compatible goggles. Refer to your HDZero goggles manual for channel scanning and selection. The VTX settings (power, channel) can typically be adjusted via Betaflight OSD (On-Screen Display) menu using your transmitter sticks or through Betaflight Configurator.

6. Matengenezo

Matengenezo ya mara kwa mara huhakikisha maisha marefu na utendakazi bora wa drone yako.

6.1 Ubadilishaji wa Propela

Damaged propellers can significantly affect flight performance and safety. Replace them immediately if bent, cracked, or chipped.

Use the provided propeller disassembly tool to carefully remove the old propeller from the motor shaft.
Ensure the new propeller is oriented correctly (clockwise or counter-clockwise rotation as indicated by markings or motor direction).
Gently push the new propeller onto the motor shaft until it sits flush. Do not force it.

6.2 Kusafisha

After flights, especially in dusty or grassy environments, clean your drone:

Use a soft brush or compressed air to remove dust and debris from motors, flight controller, and camera.
Avoid using liquids directly on electronic components.

6.3 Huduma ya Magari

Inspect motors for any signs of damage or excessive wear. Ensure they spin freely without obstruction. If a motor feels gritty or makes unusual noises, it may require replacement.
