530Flat - a Folding Concept Build

This is a concept build using a bunch of on hand parts from previous projects.

Original frame was from a Daya 680mm build with 16in props which crashed, cracking the top and bottom carbon fiber plates, couldn't be used anymore for clients, and I got it. I repaired the cracks with epoxy laminated carbon fiber pieces. I cut down the arms to to the shortest length which would allow the frame to fold, which came out to 530mm. Any shorter and the arms can't fold. I flipped the motor mounts over to reduce the z-height and printed some shims to allow the motor plates to fold without intersecting the main frame plates. Designed some 3D printed CF-PETG front, side and rear panels, along with some TPU mounts for the flat antennae for the SIYI receiver.

Overall, it was a challenging build. I didn't expect much from it but it turned out to be one of the most forgiving/fun drones I've ever flown. It was a pain in the ass to fit everything inside the frame and it could probably use a bit more power but it's a pleasure to fly as is and I love the way it looks!

Great build! To large for my field of application, but I like this Transformers-style!

Really nice and creative. what are you using it for?

It's mostly just a demonstration airframe right now. I have a 1-axis camera gimbal to it right now. I wanted a cool looking build to fly at the end of the day when taking a break from my more serious projects.

I thought this was a 3D render until I read your blurb. Love the way it looks is an understatement!

Thanks! That's huge praise!

What an awesome build!!!! I'm impressed by the folding arms, and the final shape it takes when it's all closed up!
Was the "cutout" for the GPS in the original frame?
I like the gold paint on the motor mount carbon :) Swapping it to the bottom for more centralized mass (and your stated purpose of: better portability) is clever.
I am designing a frame for 9" props. I see that you are on 10" props now. What kind of flight time are you getting on that 5200?
Do you know the AUW of this bird?

Thanks,! No, the GPS cutout was dremeled into the top plate. The motor mounts are actually electroplated aluminum not carbon! And the motors run incredibly cool temp-wise. Flight time: I'm getting 20-25mins depending on how hard I push it, but I'm still not finished tuning it, so that could change. Dry weight is 1238g and AUW is 1750g with the 4S 5200mah.

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..
