This is a 500mm quadcopter frame, mostly used for long flighst and aerial photography.
The cool thing about this frame, it’s its regidity, the arms are made of hard plastic, but inside there’s a glass fiber tube that runs through. Not only it’s hard to break, it also helps to not flex much, to have a better and stable flight.
The middle/body of the frame is made out of glass fiber. Which makes this plastic and glass fiber frame kind of light weight, not as much as a full carbon fiver one, but for the price, it is awesome!
When i was putting the frame together, some of the screw holes didn’t aligned perfectly, but not to bad, i’ve seen worse, and it was easy to correct just by applying a bit of force
