Armattan Marmotte DJI HD FPV Build

The first quad that I've built :-)

I used a 20x20 adapter to push the stack all the way to the rear of the frame.
Mounted the DJI Air unit to the front of the frame using VHB tape and a zip tie.
Mounted the FrSky R-XSR between the air unit and slightly under the stack using VHB tape and a small zip tie.

Note that the T-Motor F4 HD 30x30 stack is taller than the stock marmotte stand offs.. I had to improvise and use taller standoffs in the rear and spacers in the front.

I'm curious how you used the 20x20 stack adapter to move your stack. How did you manage that? I'm condisering doing the same but trying to wrap my brain around how you secured the stack. Looks like a really nice build!

Many thanks j4y!

I used four M3 screws and small spacers to secure the adapter to the frame via the 20x20 mounting points to the rear of the frame. The 30x30 stack then mounts to the adapter.

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..
