3" Red Black concept

I wanted to build small and slim 3" quad and I decided to use Alien frame for this build.
FC and ESC are installed side-by-side (not on top of each other) to make this build really slim.

I wanted to install FC and ESC side-by-side (which requires two 20x20 places), but this frame only had one 20x20 place. So I had to design additional 3D printed stands to make side-by-side installation possible. After these modifications distance between top and bottom plate is only 12mm.

I didn't paint the frame like I usually do (See my previous quads "Red-Black Tree" , "Bianco Arancione" or "Orange Pudang" ), but I did play around with colors red and black.

Technical details

  • Smartaudio used to control the VTX
  • XM+ with RSSI

Updates

  • Updated to Betaflight 4.1 and JESC. Also enabled RPM filters and did some overall PID tuning.

YOOO THATS SICKKK i think i might use youre quad as a basis for mine!! its also cool that you used an eos2 because it does makes sense to use a 14x14 to make it slammed. Do you have a link to your 3d printed parts for the fc and camera mount?

Thanks :+1: . Just uploaded STL-files here https://www.thingiverse.com/thing:3654010 with instructions. Have fun building :)

You have a LOT of unsupported top plate that's likely to crack from the weight of the battery when you crash, but HOOOO-SHEET does she ever look goooooooood!

just dont crash, how hard can it be hahahah. Ive used the same frame before in a build i havent shown but its possible to put something above the boards so when the topplate flexes, it has soemthing to lean on. I havent broken any toplates so far, but i did wreck the arms ahhaha.

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..

When the FatShark HDOs hit the market in 2018 the FPV community rejoiced for the new Sony OLED displays. While they lacked further upgrades like an updated DVR and power button they were still a market success. With the 2019 announcement of the Orqa FPV.One the community finally had a potential HDO killer on the horizon. With only weeks before the release of the Orqa FPV.One Skyzone came out of left..
