I've wanted to try out 3", and these new 12A AIO boards put me on a search for the most thrust I could find with 12A and 3S. In that search I found the Spintech 1304ST 5200KV motors.

1200g+ of thrust at 12A benchmarks.
Build weight 83g dry, 135g AUW

This is WAY FASTER that my previous 1103 ultralight: https://rotorbuilds.com/build/8061

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..
