My first ATV frame so I don't know much of a difference but it was fairly easy to put together and has suffered a lot. I bought a second set so I had spares but I only broke one arm and they are easy to replace. There is some extra material on the motor pads to protect the motors, but not much and there is a hole right where the spar connects to the pad. I'm not sure why it's there, but it's a weak point and that's where my arm is broken. Not a lot of space in the stack, but enough room for a flight controller and an esc. Probably good enough for a stacked VTX too, but I'm using a standalone VTX attached to the top plate. In general a good frame. Thick arms, simple design. Good components. Excellent price.
