If you notice all the stuff on the main tray, it has been placed on the outer edges to prevent the
cockpit from touching them. The UP3, Receiver, Gyro and air failsafe are just under the main
tray in front of the UAT on the new made tray. You can see by the above picture the UAT, then
we put the fuel pump on one side and a smoke pump on the other side of the UAT, the ECU and
turbine valves are just behind the UAT.
Putting every thing in place so it all connects and works properly is the hardest part. So take
you time and try to plan it all out first before you start cutting holes in your tray, as was said
before neatness counts and is a must.
In the above picture it shows air tanks above the UAT. We had to exchange there place with
our batteries in the nose because of the extra weight from the cockpit with pilots. We had to
much weight forward and it was hard to get the proper CG.
11: INSTALLING EQUIPMENT TRAY
Cut out the servo holes. Depending on the type of wood tray you are using, It might be easy to
do with a few strokes of a new exacto knife or a cutting bit on a Dremel rotary tool.
Mount the servos in place using the hardware provided with the servos.
Make up some scrap plywood blocks for under your air valves. What you want to do is raise
the valves up so they are level with the servo arms, so that there are no side loads on the valves.
You want as straight as possible a link from the servos to the valves.
Drill holes through the blocks and the equipment tray and use 2-56 blind nuts under the tray to
secure the valves to the tray. Use 3/4” 2-56 screws to mount the valves in to the blind nuts on the
tray. You can use a little dab of epoxy or CA on the blocks to secure the blocks to the radio tray.
Notice how the valves are staggered to keep from hitting each other, and to keep the airlines
that will be attached from interfering with each other.
