This is a really great looking build, planning wise. I have been thinking about making a carbon fiber frame for a while, but not the traditional design, cut from plates. What was your process, as far as the material you used, and the way you put it into/cured it in the mold? Is it recycled from other frames that have broken in the past? I don't know a ton about the process, I just heard that it's (forged carbon) made from broken pieces, and it has good compressive strength compared to other types of carbon fiber.
The project is named Fragile because I was expecting that it will be more fragile than normal carbon. But when I started to make the arms from straight fibers it gained extreme rigidity. :D This specific frame is not made for any crashing but I think it will manage to survive some crashes. I have another frame for freestyle (i will upload it today) and it is on a heavier side but I crashed it straight to a brick wall and nothing happened. :D it has similar design but the arms has 8x5mm in the widest part and 5x5 and the tip. But You can stand on it. :D
Is that mesh under the AiO some kind of RF shielding?
It definitely is. I use it just in case any interference comes from ESCs. It is a long range quad and I want the signal as clean as possible in CF frame. Here is what I used. https://www.aliexpress.com/item/1005005972956273.html
It is taped on a 3d printed plate with small standofs for the AIO unit.

AirbladeUAV has done it again and this time they've brought long range to the 5" class! Based on the popular Transformer Mini, the new Transformer 5" Ultralight adopts a lot of the same design philosophies with larger props and more payload capacity. It can fly upwards of 20 minutes on a 4 cell Li-Ion battery pack and in ideal conditions it's got a range of over 4 to 5 miles. In this guide I'll walk..

With the release of the DJI FPV Drone cinematic FPV has become a lot more accessible, but you certainly don't want to crash a $750 drone! The QAV-CINE Freybott is a compact, lightweight cinematic FPV drone that can take a hit and keep going. It's a lot safer to fly indoors and around people. With a naked GoPro or the SMO 4k you can capture some great stabilized footage. In this guide I'll show you..
