Model name is X165

This little guy is a present from a lovely friend, who probably knows my love with the little complex machines. I never thought about having this little machines anymore because, at least for like ten years or something I broke every single one of the flying machines that I have had after one or two flights. So this guy come up as a bold one and didn’t shattered to pieces in the past five days.

But it got a little problem that the buzzer, which alerts the trimming and mode changing inside the controller is bit too noisy. So already impatient for tearing apart the toy, I decided to add a trimmer to buzzer. It turns out to be look good in the end!

Unscrewed controller

Signal cable desoldered from buzzer and soldered to third pin of trimmer.

Another cable soldered between the buzzer positive pin and the second pin of trimmer.

Drilled a hole with a 4′ drill bit.

I glued the trimmer to controller. But In order to place the PCB I had to cut the end of it with a metal scissor. Fortunately this part do not have a trace or component.

Another view of the trimmer and PCB before closing it.

The end! Though I didn’t documented it, I had a problem with space covered by trimmer’s body. I cutted/destroyed the recess of buzzer in order to fit everything in.

Feels more completed 🙂
