This is an attempt to make lightest possible 5" quad, while still retaining good aerodynamics (so no extensive bracing the the propeller flow, internal cable routing, etc.), sufficient stiffness and motors big enough to handle 5" triblades/6" biblades without prop-wash issues.
It flies just great without any problems/vibrations -> https://www.youtube.com/watch?v=vsO9PqrXtQQ&t=23s
It's also surprisingly resilient and already survived one crash without any damage.
Frame is made from 6mm thin-walled (0.5mm) CFRP tubes + 3mm tubes for the support structure - weight of the frame without aerodynamic canopy is just 20g, canopy adds 4g on top of that.
I choosed Skystars koko 2004 1800kv motors with 5.1x2.5x3 props, Caddx Baby Ratel nano-cam (amazing video quality for the 14mm nano cam), JHEMCU F411AIO HD 40A, geprc tiny 400mw vtx and TrueRC singularity antenna.
The only thing which I will change is the battery, I choosed GNB 550mah 90C 6S lipo (~49A max current), unfortunately the motor-prop combo can draw almost 70A max, so there is a bad voltage sag at full-throttle.
I will exchange the 85g battery for 120C 700mah version (118g), unfortunately that will push the weight bit over 250g.

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..

This is such a cool/fun project. I would love to see a build montage!
Thanks ! There is a complete build guide with instructions and STL parts here https://github.com/janherich/Spacedrone/tree/main although so far only for regular 5"/7" builds, not this superlight 5" with 12mm motor mounts, smaller diameter tubes and slimmer canopy.
I will remember to make video next time I assemble one of those :)
