225mm FPV Racing Drone Frame Carbon Fiber 5 inch Quadcopter Freestyle Frame Kit with Lipo Battery Strap

Very good. Obviously the consumer must know assembly of drone architecture but this frame is awesome to work with.

Got this for my first drone build. Its well made and everything fits together well. It is pre chamfered which is nice. The carbon fiber bottom plate is kind of thin but its reinforced in critical spots with other plates. The arms are much thicker though presumably to help with crashes and stiffness. My only downside is that there is not a lot of space. There is room for a full stack in the center(with some limitations) but in the rear you are constrained by the VTX antenna cable. I'm still working out the best way to mount my VTX and RC receiver. I've flown it for a few hours and it flys well and has held up to some rough landings without any problems. I highly recommend it.

UPDATE: This frame is durable and handles crashes pretty well. The carbon weave is in the correct direction for the arms and they are pretty stiff and strong. I've been flying and crashing this frame for several months now and have not broken an arm yet. I like it. I haven't crashed it much so I don't know how well it holds up to that. Probably fairly well because it's thick, but if you hit trees at 80mph it's probably going to break. It's good quality, nicely made, but the screws are cheap. If you can replace the screws with good ones it would be a fantastic frame, but they're keeping the price down by using really soft and poorly made screws.

Haven’t mounted anything yet, but the frame itself seems like a thoughtful package. Nice screws and standoffs, free battery strap and anti-slip pad. Credit where it is due, you get a lot for a reasonable price, especially considering the price of many frames today. Even the screw holes make room for the conical shaped screw heads. So everything sits flush. Downsides I can see right now: no TPU included and the camera area has no adapters for Walksnail. So you’re on your own there. The cuts are not perfect and they look a bit rough but who cares about that for ~$30. Overall I think you’re getting an excellent value. But I’d still pick a TBS Source One (~$40) because they are thicker, and come with camera mounting plates. Also, TBS has a plentiful 3D printing parts community.

I printed and build 2 drones when I first got my 3d printer - when I melted the first arm and destroyed the drone I put it in a closet for 2 years until I happened upon this frame - I have been thoroughly impressed with the strength of the frame given its size - I dropped it once from about 12 feet when a battery bit the bullet (they've been sitting as well) and was happily surprised to see no damage had been incurred. The dual mounting patterns on the middle and rear of the frame were great, I printed some antenna mounts and adapter plates to make use of both of these and keep the inside of the frame looking nice and sleek.
