Office FPV Day at DIYFPV HQ - Flying Whoops and More

Office FPV day at DIYFPV HQ

After quite a long while, we finally carved out some time to zoom around the office with our whoops again! We got a few packs in with the Air 75 - which, to be honest, is teetering right on that fine line between “safe for indoor flight” and “might take out a monitor if you sneeze mid-turn.” 😅

I also tried firing up our trusty Mobula 6, but the poor thing wasn’t having it - the VTX was acting up. Not completely dead, but the video feed was very sketchy. I suspect that after one of its earlier crashes, we hadn’t noticed the antenna had partially popped off and, well… the VTX probably cooked itself.

So I decided - today’s the day the DIYFPV office fleet (Air 75, Mobula 6, Air 65, and one experimental, ultra-budget 75mm whoop) would rise again!

A couple of months back, I had ordered a TBS Unify Pro32 Nano as a replacement VTX, and figured this was the perfect time to finally put it to use - and also to properly test out the new T90B soldering iron (I’ve actually been meaning to write a post about my research into portable soldering irons - what I looked at, what I learned, and why the T90B ultimately earned its place in my toolkit. Coming soon 👀).

After tearing down the Mobula 6, I soldered everything together… before realizing I’d forgotten the SmartAudio wire 😅. Once that was sorted, it was time to dive into Betaflight and reconfigure the ports. The SuperX ELRS AIO 5-in-1 that powers the Mobula has a built-in VTX, but since that one was toast after the antenna mishap, I had to disable its UART1 configuration entirely. I then soldered the SmartAudio RX wire to TX2 on the AIO, enabled UART2 for the new VTX, loaded up the VTX table, powered on the goggles, found the right channel, and - voilà! Mobula came back to life! 🎉

Meanwhile, the Air 65 had a broken motor wire from its last flight - a quick solder fix later, and it too was back in the skies.

So, after a bit of solder smoke, UART juggling, and Betaflight tinkering, the DIYFPV office fleet is officially back in service. 🚁💪

Oh, and if you happen to spot something interesting in the photos… 👀 yes, that might just be our DIYFPV Builder - the very same tool we’ve been working day and night on to help pilots plan out their builds, pad layouts, and wiring. Totally accidental that it made it into the frame. Totally. 😏
