I don't think they were with my 4*40 either. When I first built it, I pieced together a "servo tray" out of 1/4" sticks. It worked, but it was a mess. When I rebuilt it this winter, i cut a tray out of 1/8 ply and attached it to some rails inside the fuse.

Whether or not they come in the kit, it's just a matter of cutting a couple of sticks.

I also used a couple of 1/4" sticks to mount the aileron servo in the original build. During the rebuild, I mounted dual aileron servos on plywood plates.

You can see the old and new setups in my build thread:

Good luck
