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.

Until recently GoPros were delegated to larger quads. A typical GoPro weighs around 125g and we've only recently begun to mount them on 3" cinewhoops. Even that is a stress on the motors. Now we've got the "GoPro Lite". Remove the battery, displays and casing and you're left with a small, lightweight board and sensor. Wrap it in protective TPU casing and you've got a 30g micro GoPro. The Hero6 is..

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..
