This is a semi-light 3 inch quadcopter build, the goal is to have an AUW with a GoPro und 250g, which this quad with exactly 249g reaches. This helps with a lot of regulations in europe. The power on 4S is just insane with this build, although it eats through batteries (around 70A peak amp draw). Lots of fun with and without the GoPro.

I got most of the parts on sale, total costs for me (excluding battery) was around $110. Flying Betaflight 4.1.4 with RPM filters and close to default PID values.

Some flying impression:

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..
