# Clover 4 assembly

## Fasteners size

> **Hint** During assembly, screws and racks of various sizes are used, using fasteners of the wrong size can damage the copter.
<img src="../assets/assembling_clever4_2/mounts_size_en.png" width=500 class="zoom border">

## Frame Assembly

1. Align the 4 beams with the center deck, fix them with the M3x8 screws and nuts with a nylon insert.

<div class="image-group">
<img src="../assets/assembling_clever4_2/frame_1.png" width=300 class="zoom border">
<img src="../assets/assembling_clever4_2/frame_2.png" width=300 class="zoom border">
</div>

2. Install 2 20mm posts on the center holes in the main deck and fix them with the M3x8 screws.

<img src="../assets/assembling_clever4_2/frame_3.png" width=300 class="zoom border center">

3. Install the stiffener hook into the groove in the beam.

<img src="../assets/assembling_clever4_2/frame_4.png" width=300 class="zoom border center">

4. Press the stiffeners onto the main deck.

5. Tighten the stiffeners with a small carbon deck.

<img src="../assets/assembling_clever4_2/frame_6.png" width=300 class="zoom border center">

6. Install 4 6mm nylon posts and fix them with the M3x6 screws.

<img src="../assets/assembling_clever4_2/frame_7.png" width=300 class="zoom border center">

## Installating motors

1. When installing motors, pay attention to the rotation scheme of the motors. The rotation marking on the motors must match the rotation pattern.

<img id="prop_rotation" src="../assets/assembling_clever4_0/props_rotation.png" width=300 class="zoom border center">

2. Mount the motor on the corresponding holes in the beam using **M3x5 screws**.

<img src="../assets/assembling_clever4_2/motor_2.png" width=300 class="zoom border">
</div>

> **Caution** Make sure that the motors are secured with M3x5 screws, otherwise a short circuit between the windings may occur.
## Installing ESC and PDB

1. Connect the speed controllers (ESC) to the motors using the MR30 connectors and fasten them to the beams using clamps.

<div class="image-group">
<img src="../assets/assembling_clever4_2/esc_1.png" width=300 class="zoom border">
<img src="../assets/assembling_clever4_2/esc_2.png" width=300 class="zoom border">
</div>

2. Install the power distribution board (PDB) on the pre-mounted racks and secure it with 6mm racks. The power distribution board must be installed so that the power connection cable points toward the tail of the aircraft.

<img src="../assets/assembling_clever4_2/pdb_1.png" width=300 class="zoom border center">

3. Connect the power outputs of the speed controllers to the power distribution board.

<img src="../assets/assembling_clever4_2/pdb_2.png" width=300 class="zoom border center">

## Installing Flight Controller

Set *Clover 4* allows you to install various flight controllers, for example *COEX Pix* and *Pixracer*.

> **Caution** During installation the flight controller, pay attention to the arrow located on the board, it should be directed to the copter bow.
### COEX Pix

> **Hint** Before installing the damper struts, screw 2 layers of nylon nuts, for a stronger fix or bite off the excess thread using side cutters.
Install the damper struts, fix *COEX Pix* on them with nylon nuts.

<img src="../assets/assembling_clever4_2/coex_pix.png" width=300 class="zoom border center">
