Apparently, the AOS5 V2 developed by Chris Rosser has a hella similar arm structure to my frame. But please refer to my previous build, which should prove that I did no copying. My Hex Evo is now open sourced for all to play.

6mm arms, 234mm wheelbase true x, 5mm front and back strut, 2mm plates.

Changes from my previous version to this "Evo" version:
-120g to 124g (I know you hate the extra 4g, and I do too);
-Added 6mm spine in the middle (where the extra 4g comes from) for awesome LONG TERM rigidity;
-Slimmer mid and bottom plate;
-Replaced the nylock nuts with pressnuts: easier to unscrew an arm and slightly lighter weight;
-Stronger top plate front end
-Two options of arms: regular and devil horn

Before you send it to a CNC, please refer to the two recommended carbon cut layouts in Thingiverse for the optimal performance.

I must admit that i really like the design of this frame. Is there any way you can post a video of it from YouTube?

It seems the FB links won't allow me to watch the videos.

Have you posted any video of it in action?

Thanks! Always love seeing what people are doing in the frame space. Not a big fan of the traditional designs myself but I understand why they are popular. Loved hearing what Rosser had to say about the Apex. But you definitely beat him to the punch with your design!

Very nice frame. Can I use 5mm carbon for the amrs?

SlightlyScratchedCorolla   Apr 13, 2022 

You certainly could. But it'll be a major compromise on durability because the arms are pretty narrow.

Be super careful of CF dust, it's actively bad for your health to breath that stuff. Asbestos level bad, that is.

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..
