The flywoo 65mm frame that is cut up for this build is a different plastic than say the Meteor 65 and the ducts actually provide amazing strength to lateral impacts. Especially in this size. I nailed a front lawn lamp on a post at a good speed and with crash recovery enabled in betaflight it just bounced off and kept going. I've had about 3 of these incidents so far thinking it would be a goner each time. Again, I would highly recommend this frame. Newbee drone cockroach x-durable with lifetime warranty has broken on these same impacts in the past. I have a loop in my yard as most of us likely do and the hand rail and lamp post have cost me a lot of frames. The light weight helps the bounce factor. Ill try to get some dvr footage together and post, only my batteries are shot. More arriving in two days. Left them charged for a week, forgetting, so low flight times. The 75mm version of this frame (have one in build stage) comes with option for a thicker carbon plate and it retains the same compressed X form. And it does fit the new HDZero fairly well. New nano camera is a tight fit between the ducts and not very angle adjustable though. This 65mm with the diamond f4 is a hoot. Stick position for throttle is slightly higher than my 65fastback during flight but the motors are smaller. I would not call it fragile even though its like an egg to handle. The two copper antennas make it tricky to find a finger position for picking it up. In the northeast my enemy is the wind when flying this guy.

In crashes, probably not very durable. Frame flexes easily and is thin. Would be very light build though. Screws for this come with the kit too I believe.
