To get the Losi tray in I had to:

-cut about 1/4 inch off the back of the little platform that the ESC goes on.
-I slightly lengthened 2 of the motor mount holes in the chassis with the dremmal(slightly= less that 1mm)
-I drilled & counter sunk 1 additional hole in the chassis for the "middle" tray mounting hole.

The tray is secured buy 4 4mm flatheads from the bottom up (1 in front,1 in the middle & 2 in the back.

In order to make the body fit better I dremaled off 2mm from the bottom of each of the stand-off mounts on the bottom of the tray & filed down the top of the rear 2 mud guard mounting points. Body fits perfect with a 5S 3300 pack in it. The RX is in the battery box. Everything to the rear of the battery box was cut off of the radio tray leaving only the battery box & steering servo mount.
