SummaryRear mount for vtx on the Eachine Racer 250 quadcopter. To use this you will probably have to extend your wires a couple inches. This model uses the stock screws that come with the vtx. I put 2 in opposite corners, but you could always add 2 more screws to secure it a little better if you feel like you need it. Zip-ties go around the bracket and the rear of the quadcopter. Second file is for the top piece. Not necessary, but will probably help save your vtx in a bad crash since it supports the antenna mount.
