Let’s face it, the first buzzer by ViFLY was a bit premature, and they released a few more revisions in a very short amount of time. I wasn’t a big fan of that so I skipped all of them. But it looks like they have finally settled with the V2 so I will check it out and see what improvements they made.
Buzzer can help you locate your crashed drone, but typically it won’t work if the battery is disconnected in the crash. Here we will show you how to build a DIY lost model alarm with its own little built-in battery.
