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. It is much easier to make changes before the fuselage is assembled.
NOTE: The plastic bubble wrap that protects the parts during delivery can be used on the
work bench to protect.
 Un-wrap the rear fuselage wires and tubing
leaving the bundles as shown.
The 3 bundles are from left to right:
Servo Extension Wires,
Pneumatic Tubing,
Light System Wires.
 Remove the Fuel Tank Retention Former by
backing out the (4) phillips head screws.

Joining the Aft Fuse to the Forward Fuse 4 Pin System
See next page for 6 Pin System.
Sequence:
 Test join the 2 fuse sections.
 Then separate the aft and forward sections.
 Install the Inlet Ducts.
 Then join the aft and forward fuse sections.
 Access the bag with the (4) fuse aluminum
pins and remove the 3mm SHCS from both
ends of the aluminum pins.
NOTE: Post January 2016 production
models have (6) fuse aluminum pins.
 Install (4) Aluminum Joiner Pins at the 12,
3, 6, and 9 o’clock positions of the Aft Fuse section.
 Apply Z-42 to each 3mm x13mm, then install from the rear into the aluminum pins.
NOTE: A 3mm “L” Hex wrench works well.

YAK 130
BVM ©2016 8 Mar. 23, 2016
For Post January 2016 models- 6 Pin System
 Install (4) Aluminum Joiner Pins at the 12, 3, 6, and 9 o’clock positions of the Aft Fuse
section. See previous page photos.
 Apply Z-42 to each 3mm x13mm, then install from the rear into the aluminum pins.
 Install the final (2) Aluminum Joiner Pins at the 5, and 7 o’clock positions of the Forward
Fuse section. This is necessary because the inlets will block access to the pins from the
front.
 Apply Z-42 to each 3mm x13mm, then install from the front into the aluminum pins.
For all models
 Apply Vaseline to the alignment pins to
aid assembly.
 On a flat, foam covered surface, carefully align the pins in the Aft section with their
receptacles in the Fwd section and slide the fuse halves together and install the remaining
3mm SHCS from the Fwd section. You need to move the Air Tanks to access the 3 and 9
o’clock position screws..

Inlet Duct Installation
This is the most challenging part of the assembly process. Some modeling skill and
experience will come in handy.
 Use #80 grit to sand the entire outside of the
inlets to remove all sharp splinters and edges
of the carbon cord and fiberglass.
 Use a round hand sanding tool, with #80 grit, to
smooth the edges of the fuselage flanges. This
eases the inlet duct installation.
 It may be necessary to smooth the inside
edges of the inlet duct.

YAK 130
BVM ©2016 10 Mar. 23, 2016
 Use medium Zap-A-Gap to glue these lap
seams together if needed. They might have
gotten jarred during packing and shipping.
 Inspect the Inlet Cowl Lip; use a Dremel rotary
rod grinder (#RF6C) to remove excess resin
globs from the fuselage inlet lip that might
interfere with the inlet duct fit.
 Following the trial fitting of the Inlet Duct, use an #80 grit sanding block to straighten the
aft edge of the inlet lips if needed.

YAK 130
BVM ©2016 11 Mar. 23, 2016
 Place the inlet ducts into the Fwd fuse section and tape them to the fuse in 3 or 4 places..
Right Inlet Shown Left Inlet Shown
 Remove the (6) 2.5mm x 14mm SHCS
from the Inlet retaining former in the Aft
fuse. A long 2.5mm Hex wrench is handy.
 Align the (4) Aluminum pins and slide the
fuse halves together.
Apply a thin wipe of Vaseline to the alignment
pins to aid assembly.

YAK 130
BVM ©2016 12 Mar. 23, 2016
 Use a pointed awl to align the holes in the inlet
plywood bracket to those in the fuse former.
 With the awl in one hole set, install (2) 2.5mm x
14mm SHCS per duct side. Remove the awl
and install the remaining SHCS.
A Neat Trick
 Use a scrap of note pad paper on the bolt head
and push the Hex wrench into the socket.
This will help hold the bolt onto the wrench to get it
into the tight 3 and 9 o’clock Aluminum pins.

YAK 130
BVM ©2016 13 Mar. 23, 2016
 Install the (4) 3mm x 14mm SHCS from the forward side of the fuse half. Access is
through the Cockpit opening. Use a drop of Z-42 on each SHCS.
NOTE: Both air storage tanks have been pushed aft at this time to get access to the bolts at
the 3 and 9 o’clock positions.
12 o’clock 3 o’clock
6 o’clock 9 o’clock

Spot Gluing the Inlet Ducts into the Fuse
(See also next page.)
NOTE: The aft end of the Inlet Ducts are temporarily held together with (2) #64 rubber bands.
Use clothes pins or small clamps to hold for cure.
 Use Zap-A-Gap or Slo-Zap to glue the Aft bottom and top of the Inlet Ducts at the rear
end.
Bottom Joint Top Joint
 Use dabs of a thickened epoxy glue to secure the Inlet Ducts to the fuse as shown below.
Aeropoxy is convenient for this task.
NOTE: If Inlet Ducts ever need to be removed, use a Dremel fiber cut-off wheel to separate
the joint.

Alternate Method for Gluing Inlets
NOTE: The Aft ends of the Inlet Duct are held together with #64 rubber bands.
 For a permanent bonding of the (2) Inlet
Ducts, Use Aeropoxy. .
 Inject a small amount between the aft center
flanges of the duct..
 Apply to bottom, center span, and top
junctions. Wipe excess away.
 Hold together for cure with clothes pins or
plastic clamps.
 Remove the rubber bands.

Bottom Top
 It will be necessary to trim the bottom and top Inlet center web to allow room for the
turbine F.O.D. screen. A 90 Dremel tool with a drum sander works well.
Routing Servo wires, Light wires, and Air Lines
Smoke Pump
NOTE: Some modelers opt to use the smoke
tank for extra engine fuel to extend flight time.
 Separate the smoke pump servo wire from
the smoke pump oil line and route the servo
wire forward towards the nose of the
aircraft..
 Route the blue smoke oil line aft through
the (2) formers and connect to the pre
installed metal smoke line.

YAK 130
BVM ©2016 17 Mar. 23, 2016
 Place the Air Tanks back into their original
positions.
Air Lines
 Unwrap the bundle of Air Lines and route
them forward and through the former as
shown.
 Install (2) of the Large BVM “O” Clips (part
# PA-SR-0026) at the locations shown in
the photo.

YAK 130
BVM ©2016 18 Mar. 23, 2016
 Use 4” Tie Wraps and BVM “O” Clips to secure the Air Lines. Continue to route forward as
shown.
Connect the Air lines to the Air Valves
 Connect the clear “BRAKE” line to the top of the Brake Air Valve. Use the 2mm Air Line
Collars provided to secure the Air Line to the Valve.
Slide the chrome collar over the tube; slide the tube onto
the fitting, slide the collar over the fitting to secure. Do
not allow the tubing to slide too far over the barb.
Important! Do not use wire cutters to grab the collar, they
will crush and damage the fitting.
Hint: Warm the tubing with a heat gun to help the collar
slide over the tubing.
 Connect the black Air Line labeled “THEN TAKE IT BACK” to the top of the Speed Brake
Close Air Valve.
 Connect the clear Air Line
labeled “RELEASE
BRAKE” to the top of the
Speed Brake Open valve.

Connect the Air Line 3 way/4 way Blocks
NOTE: Use the 2mm Air Line Collars to secure connections.
 When installing the Air Lines, place the
black “DOOR CLOSED” line onto the “4 way
block” with the other black “DOOR
CLOSED” air lines.
 The clear “DOOR OPEN” line onto the
“DOOR OPEN” 4 way block.
 The black “GEAR UP” line onto the “GEAR
UP” 3 way block.
 And the clear “GEAR DOWN” line on the
“GEAR DOWN” 3 way block.
Light Wires
 Untie the bundle of light wires from the aft
side of the fuse joint.
Do not disconnect any of the boards at
this time.
Picture of the Light wire shows a single #4
wire/circuit board, a #4 bundle wire set and #2
bundle wire set attached to a common circuit
board.
