2. Assembly and configuration steps for manual flights

2.1 Build chassis

First, take parts from Lightning X Lite and prepare alex keys.

We build the base like the picture below. Then, we add the upper part and use M3 screws to fix them together.

It is the time to place them on the chassis

2.2 Link ESC with power and actuation modules

Lets take Tekko32 for example.

First, we its order for motors.

Then we place four motors in the correct order. We weld them like this

After that, we weld a power wire with XT60 and a 35v 470uf capacitance to the power input of Tekko32.

2.3 Connect autopilot to ESC

Kakute H7 to Tekko32

Following the instruction shown below

we weld them like

Kakute H7 to HAKRC

2.4 Connect transmitter and receiver

It can been that RadioLink R12DSM supports S.BUS and PPM protocols.

Also, check pins of Kakute at Holybro Kakute H7 V1.

Therefore, the three ports of R12DSM should be connected to Kakute in the following way:

• "+" of R12DSM ----> 5V of Kakute
• "-" of R12DSM ----> GND of Kakute
• "S.B/PPM" of R12DSM ----> RX6 of Kakute
