Graupner GR-16: Removal of the casing

Hey Racers!

Naturally, you want your racer as light as possible, as compact as possible and remove all “useless” weight. I use a Graupner radio which has SumD (Similar to sbus) and meets all my requirements. I like the higher build quality of a Graupner radio in comparison to the most common used in the Racing scene, the Frsky Taranis.

The Reciever for the Grauper radio I use is a GR-16. It’s one of the smaller ones, but I really wanted to make it use even less space. I searched online for help about removing the casing which was sadly fruitless so I decided to do an adventure on my own.

DISCLAIMER: I do not take any responsibility for any damaged on a failed attempt to remove the case on a gr-16 receiver. please be careful!

Let’s start with the removal

Ignore the fact that mine is a little dirty, I am reusing my older receiver on a new model I am building right now. As you can see, there are four latches holding the case together.

You will need a flat tool. I used a small hand file to do this task.

 

First Step

First Step

Push the latches in like shown on the pin side and lift the case. You won’t be able to push them on the antenna side because it is blocked by the board.

The next step is the little tricky part:

Step 2: Slipping under the case

Because you can’t push the latches in on the antenna side, you need to lift the case. Carefully, insert the tool like shown in the picture and start moving upwarts slowly. With a little trickery, you can free the two latches that way and thus, you have removed the upper case!

Carefully slip the module out of the bottom case, be especially careful with the antenna! the result is a freed, decased receiver module:

Ending thought

It isn’t to hard to remove the case! you can also replace the antennas now. I usually wrap it up in heat shrink to protect it. Next step would be to learn to remove the Pins! For this, I require some more research though.

I hope this was helpful!

 

Cheers,
