We're using this frame as our first 250mm frame and we can't say enough about it. We were very pleased with how easy it was to assemble and how easy it was to put everything in it together, all the components. Our first build was the F550 hexacopter, it was big enough to learn more about the components and their placement. Whether you are building your first one or this one for someone else, we recommend this frame to everyone. Easy assembly, instructions, strength and appearance, it's perfect for us.
