The Luck Dragon (5 inch freestyle)

After building a number of sub 250g miniquads, a 4 inch build that is way too heavy for anything but cruising, and a 7" build that is way too precious to practice acro on... I decided it was time to build a simple 5" setup that could carry a gopro, fly medium range, and do freestyle. After a bit of research (and opportunistic sale hunting) I came up with this build. Went a bit try hard on the green... but I like it. The name Falkor (which Foxeer has used for their camera) comes from the movie "the neverending story" that I grew up with. Falkor (for those of you who don't know) was a luck dragon. I took this queue in the naming of the build. For now its running on stock pids/rates and flys like a champ. Future plans are to dial things in a bit more, and to upgrade the ESC's to 6S since everything else in the build supports it (other than the motors which max out at 5s) but a quick google shows there are ways to still run 6S batts with a bit of betaflight magic. Let me know what you think and if you have any questions!

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..
