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.

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.

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

Really good question. I do not own a hd cam and I don't plan to buy one but I'll check on the CAD tomorrow!

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 =)

Im fixen to start a build with those motor's! Have you had a chance to test and if so, how were they?? Cheers!!

Hey, to be honest I still do not had the opportunity to make my first fliflight. But anyway this is my very first build so I could not have any comparison point. However they feel pretty good.

Thanks for the feed back!! I hope you can get out soon and burn some packs w/ them. Cheers and happy flying!!!

This guide will walk you through the process of building your first FPV quad. The goal with this design was to build a low-cost, lightweight quad, yet powerful enough to safely carry a GoPro in close proximity areas. I chose these parts to minimize the amount of soldering at no cost to the quality. A typical build requires around 30 solders while this only needs 25. It's not a huge difference, but..

In late 2019 DJI made inroads into the FPV scene with their remarkable low-latency digital system. It gave us a 720p video feed with latency on-par with the status quo, analog video. Traditionally we've used analog video systems for low-latency video, but the video quality is far from ideal. It's a trade-off we've been willing to accept for the control. Now we've got the best of both worlds and what..
