Equipment Tray and Battery Mounting
The equipment tray layout is dependant upon the equipment selected and the builder’s
preferences. Many possibilities are possible with only one pictured below. Items to consider
when laying out your equipment tray and locating other components within the model are ease
of access to components for maintenance or adjustment, length of leads, routing of air lines and
servo wires, visibility, and effect on center of gravity.
Locate heavy components as required to assist in balancing the model on the required C.G.
location. In the model pictured, the ECU and receiver batteries were installed in the nose of the
model (forward of the nose gear door) using adhesive-backed Velcro and foam.
A 3/8” thick piece of hardwood was glued to the top of the rear former supporting the equipment
tray so that the installed tray would be approximately level.
Turbine Accessory Mounting
Location and mounting methods for the turbine accessories (ECU, solenoid valves, shutoff
valves, etc) will depend on the equipment selected, the builder preferences, ease of access,
and the available space. While this is a big model, the builder may run out of space quickly if
the layout and routings are not well planned. The installation of a JetCat P-120 is shown in the
photos below.
