WING PREPERATION
TIP SKIDZ
If you fly off a grass field there is no need to install these. If you fly from a paved runway and
don't always make perfect landings, especially in a crosswind you can add the BVM#2197
Carbon Fiber Skidz for extra protection. Follow the instructions that come with the Skidz plus
the work shown below.
 Make the required notch in the bottom skin as
shown. Note the location relative to the panel
lines.
 Use a 1/16" Carbide Cutter to add some glue
holes as shown.
 Use ZAP-RT or similar rubberized glue to
attach the Skidz as shown. Wipe away
excess before it cures.

BVM®2017 5 11/07/2017
AILERON CONTROL OPTIONS
NOTE: The Location of the Ball Link on the servo arm.
This yields proper resolution on the Aileron travels
It is also good to apply the Dry Lube to all control
linkages that are metal to metal or plastic to metal.
It is greaseless, yet a very good lubricant. BVM
#1947 does not attract dust or dirt.
MAIN WHEELS, AXLES AND BRAKES
 Before disassembly, note (photograph) the routing of the brake tubing on the strut.

BVM®2017 6 11/07/2017
 Use a 1.5mm hex wrench to loosen the set
screw that retains the axle. Check to see if
there is a flat spot ground in the axle. If not,
use a dremel cutting disc to make one as
shown. A matching cutter mark on the end of
the axle helps to properly orient it.
 Apply Parker Super "O"Lube to the brake
"O"Ring and on wheel inner drum.BVM
#5779
 Apply Super Axle Lube BVM # 5784 to the
axle from inside and outside access. Note
the nylon spacer.
 Reassemble the wheel, brake, and axle. Use
a small drop of thread locker on the set
screw. Check for free spin of wheel and
brake application.
Accomplish for both mains and the nose wheel. Of
course, the nose wheel does not have a brake.

BVM®2017 7 11/07/2017
WING SPAR AND CONNECTORS
To ease the wing attachment, slightly bevel the
ends of the carbon rods with sand paper (320
grit) then apply BVM Dry Lube (#1947) to the
rods.
Put a small tie wrap on the connectors to keep
them from falling into the wing
FUSELAGE / WING MATING SURFACES
Be sure that they have a small tie wrap on each
set as shown. This will keep them from getting lost
in the fuse. Small forceps can be used to retrieve
them if necessary.
The electrical and pneumatic connectors exit the
fuse as shown.
WING MOUNTING
The wings are retained to the fuse with (2) 3mm X
25mm front and (2) 3mm X 16mm screws at the
rear. Use a 2.0 mm hex wrench.

BVM®2017 8 11/07/2017
FUSELAGE
COOLING OPTION FOR EVF
 This step is optional, but we found it
reduced the temperature of the battery
packs on warmer days. You can make the
cut out using a BVM 1/16 Carbide Cutter.
After you make the cut out, you can use
testor’s flat black on the inside to clean up
the flange.
CANOPY COOLING OPTION
 There is a “molded- in’ detail on the back of
the canopy that can be cut out for battery
cooling air exit.
BATTERY LOCATION FOR EVF
 A strip of Velcro on the side of the fuse and the top of the battery rail is all that is
required. Apply a C.A. or epoxy finish to the tops of the wood rails to improve Velcro
adhesion.

BVM®2017 9 11/07/2017
NOTE: 3.3” dimension (circled)
. This is a good starting point for the EVF Batteries.
Your Center of Gravity can be fine-tuned aft or
forward of this position with EVF Battery placement
RX BATTERY LOCATION
Located on the left side of the fuse in front of the
fan mount
RX MOUNTING AND GYRO
This example on a BVM plane used a regular Spektrum 9030 Rx and a X-plus expander.
You can find the Rx channel mapping under Connecting Rx wires later in this manual.
NOTE: These components are constantly changing, adapt as necessary.

BVM®2017 10 11/07/2017
We Used the Demon cortex gyro on the demo
model. Located on the right side of the model,
under the fan mount. The cortex gyro will come with
its own wire harness to hook up to the Rx. Follow
mounting and wire diagram from Demon.
NOTE: Gyro technology is also changing
constantly, adapt as needed.
INTAKE AND EVF INSTALLATION
Before installing the intake, insert the intake into the
fan and check for rubbing of the spinner or the fan
on the intake spike..
You can use a pencil or a wood dowel to spin the
rotor to check for rubbing.
If the spinner is rubbing on the spike you can use a
sanding block to remove the flange on the back of
the spike
NOTE: On the first run up go slowly and listen for
any indication of rubbing If you hear anything stop
and repeat this step.

BVM®2017 11 11/07/2017
 When mounting the fan, slide the intake into
position, then slide the fan onto the inlet. This
will become the location for your fan to sit
Use a 1/16 drill bit to mark the location of the
mounting holes.
 Use 4-40 bolts and blind nuts to mount your
EVF unit in place..
We recommend using some Qt poxy to hold the
blind nuts in place. BVM # PA-SR-0042

BVM®2017 12 11/07/2017
When you are ready to install the duct we
recommend that you use a few dabs of Zap
Goo on the intake lip and slide it in to position.
Make sure the Intake spike is vertical. This
should only be done after all the test fitting is
complete.
EVF unit installed.
TAILPIPE INSTALLATION
NOTE: See instructions that come with the mylar tailpipe
The tailpipe is rolled in on the bottom and installed through the opening of the rear fuse. The
pipe is held to the fan shroud using two Button head screws. These screws are provided in
the tailpipe install kit. You will need to drill two 1/16
th
holes for these screws.

BVM®2017 13 11/07/2017
NOTE: ONLY USE THE TAPE PROVIDED
Use the tape provided to seal the front opening of
the tailpipe. Use one piece on the forward seam of
the opening and then three pieces across the
opening. This is a time tested method that works.
Once the pipe is in you can trim the pipe to match
the rear opening of the fuselage. You can also
remove the pipe and use flat black testers to paint
the pipe on the outside.

BVM®2017 14 11/07/2017
STABS AND ELEVATORS
NOTE: Stab retaining bolts should be packaged with the wing retaining bolts. They are 2mm
X 16mm socket head machine screws that require a 1.5mm hex wrench to install.
 Chamfer the ends of the (2) carbon rods and
lube with BVM Dry Lube as done with the
wing tubes. Make the electrical connection
as shown and insert the carbon rods. Use a
servo lead connector lock or tape to secure
the connections.
 Use a 1.5mm hex wrench to insert and snug
tight the 2mm bolts.
NOTE: The elevator neutral position is located as
shown.
See controls Set-Up page later in the manual for proper Elevator, Aileron, Rudder, and Flap
Travels.

CENTER OF GRAVITY
The Center of Gravity is located on the forward
inboard screw of the main gear flex plate.
NOTE: Your final C.G. can be fined tuned by moving
your BVM Flight packs forward or aft.
FUSELAGE AND COMPONENTS
NOSE GEAR SYSTEM
The nose gear, strut, and its flex arm mounting system comes installed and ready to use. The
following instructions will help you remove and replace the system should that become
necessary.
NOTE: Inlet duct must be removed.
 Disconnect the forward folding door spring
from the strut.
 The nose gear flex arms are as shown here.
Use a 2.5mm hex wrench to remove the
bolts.
 Disconnect the nose gear steering linkage from the tiller arm.
 Remove the (4) flat head machine screws that mount the retract unit to the flex arms.
 Remove the flex arms from the model one at a time. They must slide outboard and aft
to disengage the slot in the most forward bulkhead.

BVM®2017 17 11/07/2017
 Maneuver the retract unit to get it out of the
model. Use a BVM Collar Tool to disconnect
the pneumatic lines from the nipples on the

First Flight Profile
Flight Time
The BVM demo model’s transmitter timers are set for 5 min. On the first flight, land a minute
early to check battery consumption. Adjust the flight timer accordingly. BVM uses the 80%
rule for battery usage.
Taxi Test/Engine Run Up
A taxi test should include a radio range check with the engine running at various power
levels. Check that the wheel brakes are adequate and the stopping action is without skidding
or pulling left or right.
Takeoff
Make the first takeoff and climb out with the gyro off. Begin the takeoff roll by slowly
advancing the throttle. Maintain runway center while holding about 1/2 stick up elevator; the
Sabre will rotate when it is ready. It there is a cross wind, hold a small amount of aileron into
the wind, apply opposite rudder as necessary.
Trim
Once in the air, use a medium cruise speed to set the trims. The aircraft should fly straight
and level when “hands off”. When the landing gear comes down, a few clicks of up trim will
be needed. This can be mixed in, or use flight modes to trim automatically.
Practice Approaches
Plan to allow at least one half of the first flight to practice approaches and go arounds. It is
beneficial to become familiar with the low speed handing of the aircraft at altitude first. Save
the aerobatics and air show stuff for later flights.
Landing
Landing is like most jets, “power on” during the approach. The Sabre is very resistant to stall,
it is best to land nose high, touching on the main wheels first.
RX Battery Consumption
The average flight consumes about 500 mAh. We recommend three flights and recharge.
Use this data to calculate how many flights you can achieve from your system.
