Starting small with a 3 incher, as a first build bigger than a whoop - starting as a clone of MRM Micro Scythe 3" with various tweaks and changes as I learnt about the components.
I had a few issues to deal with. For some reason I could never get the SBUS input on the flight controller to work correctly. I bridged the pins required, but the signal voltage was pinned at 3v. I gave up and wired up an NPN signal inverter, and used another UART input. I also soon realised that the so-called BEC on the flight controller wasn't going to drive VTX and camera without burning out or going into thermal shutdown. Maybe there's different versions of this board and I got an older one with a linear regulator. I addressed this with an external 7805 regulator for now, though when I change to 4S batteries I'll swap this for a switching regulator.
All this meant that I had to work out how to fit the VTX, the XM+ receiver, and a handful of discrete components somewhere in the frame, I ended up wiring everything onto a bit of perfboard, along with connectors. That way I can break the whole thing down without soldering.
Not pretty - but it works. My first flights on a brushless quad have been a lot of fun.
AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..

never seen a breadboard used as a pdb. how's it working?
So far so good. I've only had one session so far (3 battery packs). But I'm pleased with how it works. It's a big upgrade in performance from a tiny whoop!
