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!

what is the AUW and what flight time you are getting?

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!

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
