Daya H4 680 rebuild

After my good experiences using Arducopter on miniquad flight controllers in my Everycopter Y6 & flat hex, I decided to rebuild my 680 quad by ripping out its Pixhawk & replacing it with another Matek F405 STD. The space saving meant that I could fit everything (except the GPS) between the main body plates, resulting in a much neater build that's also more flexible & easier to use as I can just strap batteries to the body on top like a miniquad.

I also took the opportunity to swap the arms front/back, because they were backwards before. The way that I originally wired the motors means the arms no longer close all the way, but it's good enough.

I ditched the FPV gear as I never used it. I have a FPV pod I can strap on if a live video feed is really required. All flight data I might need (battery, number of satellites, etc.) comes down via SmartPort telemetry to Flight Deck, so OSD is superfluous.

Not my neatest build, but I'm beginning to accept that I have too many projects on the go these days to strive for perfection in everything!

Besides the obvious given the 360 camera, what do you use this quad for?

Honestly? Not much. I just enjoy building things.

I'm right with you, this hobby is addicting.

I've gotta say, it seems like a way more practical build now it has the whole top plate 'clean' for strapping stuff to!

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..
