This tray is built to hold your X4rSB on the top or bottom of the top plate on the "grasshopper" Diatone ET160 frame. Please note that the two pictures show the 2 revisions of this part with the final revision being the white part that is further to the back of the quadcopter to allow for more space for wires.
This part is built to be lightweight and to compliment my other 2 parts to minimize weight. The ET160 in the pic is a sub-250g build including battery.
The part assumes that you will modify your RX so that the antennas come out the connector side of the part. This saves a lot of space in your microquad. To do this just open up your X4rsb and twist the antennas 180 degrees, then add a touch of hot glue to the connector to keep it secure and in place. The antennas will then come out right next to the pins on the RX. This part works well with my VTX tray which now has antenna guides built into it.
-If you want a small LED strip on the back of your quad, the back of this part has just enough space to mount one, check your prop clearance when doing this.
-I built in some structure that will need to be cut off.
