My goal was to build as cheap quad as possible without compromising on essential components quality. So far it seems that hobbywing xrotors and sunnysky motors combo is the best bang for buck (I'm in EU so ordering better motors like cobras cost me more).
It's a custom designed frame cut from 5mm polycarbonate with 3D printed canopy/case. I wanted to maximise frame dirt-proofness up to the point where it could be made almost waterproof.
ESC-s are mounted on arms and vtx is sticked against fpv camera with metal casing so that provides some cooling even though vtx is sealed inside. There's also a foam made battery cover but I'll try to draw nicer solution soon. Also, there are going to be changes - I'll remove current lipo buzzer, rotate vtx 90 degrees so antenna goes away from battery, also may try to separate vtx from fpv camera but still keep them in one detachable block.
It's possible to use 2204 motors to reduce some weight but 2207-s are more fun, especially with 4S battery
AUW is aroung 560g with 1300mah nanotech battery.

Very unique build! How did you cut that bottom plate?

Good old dremel and hacksaw. Holes are by no means perfect but I did print out template/stencil and glued it on PC plate before cutting and drilling. CNC-ing would give much better results though.

Oh wow, that must have taken a lot of time! It looks very rigid though. How does it hold up to crashes?

What materials are you using to build the frame?

Well now your draft list can be legitimized. Looking forward to a photo!

Added some now. Btw, is there a way to add comments to photos or sort them?

I'm actually working on that. I'm reworking the discussion to make it work more like a build log.

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..
