I've been wanting to learn about dRonin, navigation, gimbals, and other gadgetry so I've started building this. Still printing gimbal parts, but it's flying with a decent autotune already. Foxeer NightWolf V2 is incredible in the dark. Hopefully this build will end up being a smooth cruiser with a gimballed hd cam.

I didn't set out for it to be super cheap, but the frame was $13, the motors $50, spare dji arms in black were $3, CAM 9x5 prop set was $10, and some of the other stuff is dirt cheap. ESC is from my junk box. The FC was pricey but it is by far the most feature rich I've ever used. I love dRonin OSD. Multiple pages of custom telemetry! :)

The gimbal is going to be based on the Primbal Session on thingiverse, and only 2 axis to start. I want to design a retractable 3 axis contraption later on.

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
