Balanced and Low Profil Quad
Home made frame design inspired by the vert racer frame. Compact, robust and balanced mid budget quad. Design has been optimized using finite element analysis. Not really relevant but it was fun.
It is my first quad so it has been a bit tricky to build but I believe experienced person could build it easily. Thanks you for watching =)
If interested, the frame can be found in Armattan Prod.

Looks really good for your first build.
Question, How much does this weight?
I ask because, this Armattan frame looks a bit on the heavy side if your going to race it. (most armattans are) Otherwise for Acro this should be about perfect. Which i think was the original intent of the frame to be honnest.
Other thoughts...
-Get a runcam split, they're great for inflight DVR and weigh next to nothing comparied to a GoPro.
-Try building a few micro quads (3" or smaller) as this will help you develop your build and soldering skills while not breaking the bank in the process. Besides, most of them can be flown indoors when the weather is sour.
Hey thank you for your comment =)
I do not know the weight by heart but yes it was a bit heavy, juste the carbon frame is about 80gr.
Sadly the build is really tight so it would not be possible to fit the additionnal board of the split.
I am currently working on another prototype which will be a 2.5 or 3 inch quad using a unique arm design based on two carbon tube (it's my profil picture). I'm puting a lot of work to design and redesign it to achieve something as clean and usable as possible. And it will be using a Turtle V2 for HD records =)
are the props in the view of the hd camera
So I just checked and the maximal vertical fov angle required to hide the props is about 74°. If I understood correctly the doc of the Gopro session 5 it mean that props would be visible only for the the wide mode in 4:3. For all the other mode you should not see the props.
I Joined the fov modeling I realized on the CAD. These are the wide and medium mode for 4:3.
Hope it answer your question =)

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 good looking first build, with the fact that its your design (inspired or not) makes it even cooler. how has it held up? any breakages where expected by the FEA?
Thanks for the positive comment !
FEA has been mainly usefull to highlight that the weakest location in case of crash on the front arm is located just after the "motor plate" where the arms are getting thinner. It allowed me to used 2mm thick upper and bottom main plate as the stress in these parts is low. The fact that they are 10 mm appart one from another create a composite sandwich effect and give it a lot of rigidity.
Sadly I'm more into building quad than flying them, I need fly more to be able to tell you how it withstand crash in real life.
