With my recommended parts it can be built to weigh only 116g and with the recommended LiPo it weighs 176g ready for takeoff.

When cruising slowly I got a flight time of over 8mins with the HQ TR2.5x2.5x3 Props.

Its mainly designed as a freestyle Quad offering good performance in a very small package while protecting the O4 Pro Camera very well.

Build it for freestyle with arm guards, tiny linear whip antennas for the O4 Pro and the protective camera mount.

Alternatively build it for exploring / cruising with a bigger LiPo, stock O4 Pro Antennas, GPS and an ND-Filter. My example build with these add-ons and a Tattu R-Line 4s 850mah Lipo included weighs in at 223g.

Here is a Link to the Makerworld Post that has all the info about it that you could want: [https://makerworld.com/en/models/1313359-ryn25-2-5-dji-o4-pro-fpv-drone-frame-3d-prints#profileId-1443461](https://makerworld.com/en/models/1313359-ryn25-2-5-dji-o4-pro-fpv-drone-frame-3d-prints#profileId-1443461)

(including a link to buy the Frame in the EU).

I designed this Frame for myself because I felt any other Frame I tried could still be optimized more. Went through 6 prototypes and was so happy with the end result that I wanted to share it with the community. Let me know what you think!

I made my own ultra light and yet still very durable 2.5" Frame for the O4 Pro, what do you think?
