This is a light weight drone that only supports a 20x20 stack. It can mount 4 20x20 boards so it is perfect for a nice light HD quad with a run-cam split mini in it. Its meant to have a top-mount battery.

The stand-off spacing is 30.5 - any 30.5 printable quadcopter accessories should work with this quad.

It's 73Grams with the 3 inch arms.

I've done up 3 sets of arms

• 3" arms - will fit any 2.5" or 3" props
• 4" arms - will fit any 3.5" or 4" prop
• 4" angled arms - will fit any 3.5" or 4" prop.

I prefer the angled arms as you should't get the props in view. I've built an arm bar for the 4" angled arms as well to add strength, its optional and if you're trying to shave weight then don't run them. :) I'll do a 3" bar as well if anyone needs it. If you're more experienced, I would suggest flying 3" without the bar anyways to shave off the grams.

Its meant to use 20mm stand-offs as this is the height of the camera mount. The camera mount will hold any camera that is 19mm wide.

I am still working out the best way to mount the camera mounts.. If you have a 3m tap set, you can add threads and use metal 3m screws to mount it. If not, I think a 2.5m screw can go through from top to bottom and hold it nicely.

Let me know your thoughts & ideas to improve this frame as I really love this design.

I will be doing a video on this frame soon on my Youtube channel: https://www.youtube.com/channel/UCf3N91uCav6kT_wBWUKVg5Q
