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!

For the longest time we've been limited to 3 to 4 minutes of flight and lots and lots of batteries. With more efficient motors and frame designs it's now possible to push the envelope much further. This guide will walk you through the process of building a micro long range quad capable of flying 8-30 minutes and more than 4km. The build is moderately difficult, but with the right tools and steady hands..

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..
