VP-X Installation and Operating Manual
Rev. D (August 5, 2020)
• Do not mount where occupants can easily touch, kick, bump, or
otherwise disturb the VP-X.
• The wiring harnesses for the VP-X should be secured at a point near
the VP-X.
Recommended VP-X mounting locations:
RV-7, 9, 10:
horizontally under the intermediate bulkhead (located between
the firewall and instrument panel) using fabricated angle aluminum brackets.
The VP-X is positioned roughly above the rudder pedal assembly, mounted
to the brackets/intermediate bulkhead. For easy access, the VP-X can be
mounted hanging downward from the brackets.
RV-8
: in the right foot well, behind the panel on the intermediate bulkhead, or
on braces above the rudder pedals. Be mindful of water coming in through
the baggage door.
Glastar
: Behind the panel.
Lancair Legacy:
on the avionics tray in front of the instrument panel, along
the tunnel behind the seats, or in the aft section of the fuselage.
Lancair ES, IV-P:
on the avionics tray in front of the instrument panel,
forward of the door along the fuselage, or in the aft section of the fuselage
(within the pressure vessel).
Note on mounting the VP-X in the rear of the aircraft
:
You can mount the VP-X in the aft section of the aircraft, but be
aware of the wire runs required for the switches. This may be
attractive when space behind the panel is crowded. However,
use of the standard VP-X wiring harnesses assume the VP-X
is mounted up front near the instrument panel. You will need to
modify the standard harness to accommodate the longer wire
runs to the avionics and other equipment mounted in the front of
the aircraft.
The VP-X uses two mounting brackets. Each bracket attaches to a side of
the VP-X using two 6-32 screws. DO NOT USE THE SCREW HOLES ON
THE BOTTOM OF THE CASE TO MOUNT THE VP-X. The brackets are
pre-drilled to attach to the VP-X. The other edge of each bracket is not drilled
so you can drill it as desired or rivet nut plates onto the bracket. The VP-X
should be secured with a minimum of two screws on each mounting bracket.
When considering the mounting sub-structure, remember that the VP-X only
weighs 2 lbs.
Mount the VP-X using two 6-32 screws on each side.
Brackets shown are supplied with the VP-X.
DO NOT use any of the eight threaded inserts on the
bottom of the case to mount the VP-X.
VP-X mounting:
• Mount the VP-X so that it is securely attached to the mounting
surface using the supplied mounting brackets or your own custom
brackets.
• If mounting in a composite aircraft, or on non-conductive surface, run
a wire from the VP-X chassis to the main ground block. Use a ring
terminal around the mounting screws (the 6-32 screws on the side of
the unit).
