Bought this frame because I kept breaking something on my iflight xl6 v3 and it was getting more expensive, had to keep ordering a new frame for parts. The parts of this quad fit together perfectly. The only thing on this frame is the levers are attached with 2 screws and on the iflight the levers are attached with 3 screws. You can either leave it with 2 screws and it will work just fine, or you can do what I did and quickly drill a small third hole to mark its location. The screws went in fine and you can't even tell it's from another frame! Requires 2 arms and a top plate and my quads look great!
