DJI RC (mini 3 with display) controller disassembly

MaximusCZ · May 29, 2022

Ill edit this post as I continue exploring

So since I couldn't find a video to disassemble to DJI RC, I said to myself "how hard can it be anyways" and disassembled it.

Here is first few photos:

If anyone wanna see anything specific, let me know before I close it again

So far:
4 screws total. 2 from bottom in the hole (visible), 2 under the glued rubber stick holder
Started from the bottom, under charging USB-C port, afterwards I think its the best place to start.
Used two dull dining knives to open. I tried plastic tools but it bends too much. Surprisingly few scars (if any) on the plastic of controller, its tough stuff.

Add the RC1A/B antennae to it and it performs way better

as this is my first drone, I have no extra antennae to add. You also disassembled the RC?

SpinItUp · May 29, 2022

Edit; looks like I'm in conversation with a veteran here!

Thats what you get when a forum dedicated to talking about drones decides its mandatory for every person to disclose their birthday and location

What angles would you like me to take?

How the are connected so we can see if it is possible to put other antennes

Hope this helps.
Its only one wire soldered to it. Cant see where the other end ends, as its beneath heatsink, which I have no plan on removing yet.

Edit: SpinItUp posted a nice photo showing the connectors above

Easy half hour job

pshaw... I can already do what the OP has illustrated. It's the reassembly, not having any leftover parts... and a video showing an operating drone again that has me scratching my head. ;-)

Is it possible to tighten the gimbals from the back? They are a little too soft for me. I’d love to know if you don’t mind looking?

Thank you.

If you are prepared to drill holes through your new controller and use plastic washers to push the aerials through.
Gimbals what do you mean?

The controller sticks. They are very weak in spring return rate. Makes the control sloppy.

If we can tighten the stick tension it will help.

It's because it's a very light controller so the action of the sticks will seem like that but it seems fine to me.

There are two springs per stick (one for up/down and one for left/right) thats affecting the force. You would probably have to replace them with something shorter
