Finally, I had some time yesterday to perform the mod. Together with all the recording, it took me around one hour and it’s actually quite easy. You just have to take your time when removing the glue around the existing connectors and it’s a bit tricky to connect the new wires.
Here is how the controller looks when open
When hooking up new connectors you have to make sure that they are absolutely parallel to the board, then apply pressure and you would hear a click. I have also used a glue gun, which I picked up for around £7 and I think it’s a must.
I have also removed the old 2.4 GHz antennas, which are actually very small. No surprises here, in my case the video feed would cut out after 100 metres.
The kit comes with two directional 2.4 GHz 7dBi antennas for the video feed and one 10 dBi 5.4 GHz antenna for controlling the drone.
The mod promises significantly longer range – up to x4 times! I’m hoping to have the video feed up to 0.5km and control range of around 1km.
The best thing about the mod is that it allows using any standard WiFi antennas and further extend the range by using WiFi amplifiers.
Here is the recording of the job, compressed into 5 mins
