Unpacking
Carefully remove items from the box. Open each package and inspect for shipping damage.
After reading this entire manual, get familiar with the major kit components.
Note: Damaged parts must be reported to BVM within 7 days of receiving your kit.
Become familiar with the work completed at the factory. It is important that you inspect and
approve this work now.
Preparing to work
 Support the fuselage on a stand. Be sure to use foam padding to prevent scratching
and denting.
 Fill air system to around 50 Psi, use a piece of scrap air line pressed into the BVM Fill
Valve (typical).
Note: There may be sufficient air pressure from the factory.
 Remove the masking tape securing the gear doors and body flaps in closed position.
NOTE: The electronic valves can be operated manually by depressing the small orange
buttons on the valves that corresponds to the action desired. Label the valves for easy
reference. Fill the air system to around 50 psi.
 Manually extend the landing gear by pressing the small orange buttons located on the
front of the electronic valves, follow the sequence below.
To Extend the Gear
1. Main Door Open (M.O.)
2. Nose Door Open (N.O.)
3. Landing Gear Down (G.D.)
4. Main Door Close (M.C.)
To Retract the Gear
1. Main Door Open (M.O.)
2. Landing Gear Up (G.U.)
3. Nose Door Close (N.C.)
4. Main Door Close (M.C.)
Note: Now the fuselage can rest on the landing gear if you prefer versus using a work stand.

Tail section
Painting Rudder and Elevator Linkages
 Apply Pacer Z-42 to the rudder pushrod
clevises.
An easy cosmetic improvement for your Cougar is to brush paint the external rudder and
elevator linkages. Use the appropriate color and small brush. Avoid getting paint on the clevis
pins or the ball links. The servo cover screw heads can be hidden with paint as well.
NOTE: The color paint on your BVM Cougar is blended to match U.S. Federal Standard
(F.S.) Numbers. These F.S. number paints are available from Testor’s “Model Master” plastic
model paints.
I.e. the dark blue on this prototype Cougar is identified as F.S. 15042 Gloss Sea Blue.

BVM ®2015 8 Printed 7/3/2019
Installing the Horizontal Stabilizer
 Remove the (4) 4mm bolts. The front bolts
are 30mm long and the rear bolts ar 25mm
long.
 Use a 2mm Allen wrench and pliers to hold
the nut to disconnect the elevator pushrods
from the control horns.
 Install the stabilizer by carefully routing the
pushrods through the openings.
NOTE: Secure the elevator servo
connection with a plastic clip or tape.
 Apply a drop of Pacer Z-42 to the (4)
stabilizer bolts and secure the stab to the
fuselage with a 3mm Allen wrench.

BVM ®2015 9 Printed 7/3/2019
 Use a Perma Grit Flat File if required to
achieve full elevator deflection.
See Control “Travels” at end of this manual.
 Reconnect the (2) elevator ball links.
 Apply a drop of Z-42 on the end of the bolt
that protrudes beyond the nut.

BVM ®2015 10 Printed 7/3/2019
Installing the Vertical Fin
 Remove the 2 mm bolt from the bottom of
the rear aluminum rod.
 You may wish to enlarge the hole for the
wire and connector to pass through.
NOTE: If the fin tubes (3) fit is a bit tight when
installing onto the fuselage, follow the (2) steps
below.
 Use a Drum Sander to chamfer the ends of
the three tubes/rods.
 Use 320 grit sand paper to stroke the rods
in the long direction. The grain should be
the same as the direction of insertion.
 Apply a small amount of Lube to three
tubes.

BVM ®2015 11 Printed 7/3/2019
 Connect Fin strobe light connection.
 Insert wires into the fin while installing the fin
onto the fuselage.
 Hold the front of the fin down firmly while
tightening the front clamp bolt; use a 3mm
Allen wrench.
Important! The clamping bolt has an “E” clip on the
end of the bolt to prevent the bolt from falling out
during transportation. Do not continue to loosen the
bolt once you feel the resistance of the “E” clip, you
will damage and loose the “E” clip.
 Install the rear rudder post bolt through the
lower rudder using a 2mm Allen wrench.

Mid Fuselage Section
Installing the Engine
The engine bay comes with the engine rails,
tailpipe, and smoke tube factory installed. The rails
are made to accept various engine installations
with minor trimming. This installation features the
Jet Cat P-100RX, other installations will be
accomplished using the same steps with minor
variations.
 Prepare the engine and engine mount. The
standard P-100RX mount supplied with the
engine is used in this prototype. Use the #6
Truss Head screws provided from BVM to
secure the engine.
 Set the engine and mount in place, get
familiar with the next few steps before
proceeding.
 Consult your engine manufacture for the
distance between the bellmouth and the
tailcone of the engine. A distance of 5/8” is
used with the P-100RX as shown.
Note: The engine mounting rails will require
trimming for the engine mount to sit on the
rails.
 Not shown in these steps, but use a F.O.D. screen.

BVM ®2015 13 Printed 7/3/2019
 Remove the smoke tube.
 Remove the tail pipe screws and slide the
tailpipe aft to allow access to the engine
mounting rail bolts.
 Remove the engine mounting rail bolts with
a 2mm Allen wrench.

BVM ®2015 14 Printed 7/3/2019
 Mark and trim the rails at a distance of .3” as
shown.
This sample accommodates a Jet Cat P-100RX.
Note: When installing a King Tech K-100G Mark
and trim the rails at a distance of .4”.
 Reinstall the rails and the tail pipe. The
smoke tube will be reinstalled after the
engine is mounted.
 With the engine set at the appropriate
distance and centered within the tail pipe,
mark the (4) mounting holes.
JetCat P-100RX distance from bellmouth = 7/8”
KingTech K-100G distance = 7/8”-1”
 Use a 6” long 1/16” drill to make the (4)
holes for the #6 Truss Head wood screws.

BVM ®2015 15 Printed 7/3/2019
 Install the #6 Truss Head wood screws.
 Reinstall the Smoke Tube.
Note: If your engine mount interferes with the
smoke tube, see the section titled Relocating the
Smoke Tube.
 Route the engine fuel and electrical lines.
Use small zip ties to maintain security and
an organized installation. Not shown here,
but use a F.O.D. screen.

General Preparation
 Un-wrap and familiarize yourself with the fuselage servo wires.
 Arrange servo wires, fuel line, light system, and air line neatly into groups. Keeping an
organized installation can help diagnose problems down the road.
 Check fuel tank installation and factory plumbing. Blow through the main supply line. It
should not be blocked or restrictive.
 Remove the front radio/ECU tray to ease installation of components. Two Phillips head
screws secure the tray into position.
Mount the BVM UAT
 Two 11” zip ties are used to secure the
BVM UAT between its mounts.
Mount the Fuel Pump
 Secure the fuel pump using an 8” zip tie.
(King Tech fuel pump shown)

BVM ®2015 17 Printed 7/3/2019
Mount the ECU
 Secure the ECU in place with wide “Sticky”
Velcro; supplied with the BVM Manual
packages. If your ECU allows for screws,
they could be used as well.
Mount the Receiver
 Secure the receiver in place with wide
“Sticky” Velcro.
 Use a 7” length of 6mm fuel tubing to
connect the UAT output to the input of the
fuel pump.
 Use a short piece of 4mm fuel tubing as an
adaptor for the larger 6mm tubing on the
pump input barb.
 Use safety wire to secure the connection.

BVM ®2015 18 Printed 7/3/2019
X+8 Xpander and Optional Gyro
 Use sticky back Velcro to secure the X+8
Expansion Module.
 Refer to your gyro manufacturer’s
recommendations for mounting your
(optional) gyro.
 BVM adds a Velcro strap for security.
The Cortex gyro is shown. The gain values
used are 40% for normal flight and 60% for
landing.
Important!!! DO NOT use heading mode unless you are experienced with this mode.
Misc Fuel Lines
 Add a 13” length of 4mm fuel line to the fuel
pump and an 18” length of 6mm to the UAT
fill barb.
The remaining brass barb will be connected to the
fuel tank after the tray is installed.
Use safety wire to secure and prevent leaks.
Reinstall the Radio/ECU Tray
Note: These photos are from an earlier
prototype. The UAT was mounted pointing
forward on this model.
 Slide the tray through the opening as
shown. Once in position, check for pinched
wires or air tubing.
 Reinstall the smoke pump after the tray is in
position. An 8” zip tie can be started with the
tray out of the aircraft.

BVM ®2015 19 Printed 7/3/2019
 Reinstall the (2) Phillips head screws to
secure the tray.
Switch
 Mount the Receiver’s switch in the location provided.

BVM ®2015 20 Printed 7/3/2019
 Mount Remote Receivers in various positions, follow the recommendations for your
particular receiver. Use Aluminum Tape to secure the wires.
