builder. (see section after Nose Door Cut Out)
With the Nose Cone taped in place, Glue the two
upper tube supports in place with Vpoxy or
Aeropoxy.
MAIN GEAR CUT OUT
Cut out the scribed line for the strut/wheel cavity.
(NOTE: The scribed line has been marked with a
sharpie for the photo). Repeat other side.
Test fit the retract. May have to expand parts of
the opening. Mark the center of the four screw
points for the flexplate. Drill down about .6” with
a 3/32 bit. Secure with four M3.5x16 screws per
retract.

NOSE DOOR CUT OUT
The Nose Door area has been scribed by the factory. There is two parts for the Nose Gear
Door. The forward square section that will act as a speed brake when the gear are in the
down position, and the rear section which is open to allow the strut and wheel to recess.
Using 80 grit sandpaper or a scuff
board, sand the inside of the fuse
where Nose Door and all the formers
will be glued.
Tape the outside edge of the forward
speed brake section and carefully cut
the lines using a diamond cutting
wheel. Do not discard this part and
make note of the forward end.
Tape around the strut/wheel section
and cut out using the diamond wheel
and other Dremel bits that will allow
you to make the curved cuts
easier.THIS PART IS NOT REUSED.

BUILD THE NOSE GEAR FORMERS
Using the parts pictured, you will need to build
the Nose Gear formers.
(Note; the three Nose Cone formers have been
factory installed.)
Glue together each of the parts that
make up the Nose Gear Formers.
There are two sets of the straight

Assembly & Operation Manual
BVM ® 2023 7 12/2023
Attach the tray mount brackets and
the two sets of tray securing tabs to
the NG Formers
INSTALLING THE NOSE GEAR FORMERS
Place the model in a stand and level the model by the wing tubes.
Place the two plywood doughnuts
on the carbon tubes of the Nose
Cone Former. Do not glue yet.
Install the retract onto the flexplate
and formers. Place the formers into
the model with the tray mounts
securely to the nose former and the
fuse bottom as shown.
Check that the strut is straight
down when extended and swings
straight back into the pocket. The
wheel should be inside the fuse.
When satisfied, tack glue with some
medium CA and then glue using
Vpoxy or Aeropoxy as shown in the
photo.
Note: It is a good idea to bevel the edges of the formers where they meet the fuse to allow
for better glue adhesion Also finger wipe to create a fillet with the glue for a cleaner install..
Glue the two plywood doughnuts to the Carbon Tube and the forward Nose Gear
Former as shown in the picture above.

blocks using a 1/16 bit for the screws.
Before glueing in the UAT tray. Bevel the outside edges about
45 deg of the two vertical pieces.
UAT Tray assembled

CANOPY
NOTE: Do one canopy hook at a time, best to start with the
forward canopy hook first.
File the notch in the ply frame as necessary for a
snug fit of the hook. Use this same Perma Grit file
to scuff the hook flanges for glue adhesion.
Cut the forward canopy hooks upper portion to look
like the photo to allow better fit ,
To ease the entry of a hook into it’s slot, chamfer the
leading edges with Perma Grit tools.
Use the 1/64” x ½” x 8” plywood strip (supplied in kit)
spanned across the bottom edge of the canopy to
set the vertical position of the (4) hooks (Kingcat) or
(2) hooks for the Bobcat.
Tack glue (Zap-A-Gap) one hook at a time to the ply
frame. Trial fit to the mating slot in the fuselage
flange. Use a Perma Grit file to adjust this slot left,
right, fore, and aft as necessary for a perfect canopy
fit and easy aft sliding release.
After all canopy hooks are installed; apply Aero or Vpoxy to each hook and the ply
frame.

CANOPY LATCH
Carefully Dremel the marked slot, test fit the Hatch
Latch to insure a good fit to the slot. Once satisfied
scuff the side of the Hatch Latch that will come in
contact with the fuse. Also scuff the fuse with some
sandpaper.
Glue the Hatch Latch using QTpoxy.
After cure, put tape on both sides of a straight blade
to protect the paint.
Use the blade to trim the plastic back to the fuse.
Place masking tape at the approximate location
where the Hatch Latch pin will strike the canopy
frame.
Use a sharpie or something similar, mark on the tip
the hatch pin, place the canopy in position, and let
the hatch pin strike the tape a few time to mark the
spot.
Use a 3mm or #31 drill to make a hole at the
marked spot.
Test fit the canopy and Hatch Latch to insure the
are working correctly.
Taper the forward end of the carbon fiber receptacle and glue into place lining up the
holes.

STABS
Install the servo in each of the servo plates with
the arms neutral at 90 deg of the plate. Make
note that the slots are to the inside and aft in the
opening.
Using a Dremel, carefully clean up the outline of
the servo pocket.
Using the servo plate, drill the four corner screw
holes with a 1/16 bit, then reinforce the holes
with a drop of thin CA.
Scuff both bottom sides of the elevator control
horns to aid in adhesion.
IMPORTANT: The clevis hole in all control
horns should be drilled through with a sharp
and accurate 1/16” drill bit before installing
into surface. Test fit a clevis pin in each of the
holes. It should be a snug fit.

KingCat-V2
Assembly & Operation Manual
BVM ® 2023 15 12/2023
Apply Aeropoxy to slot and holes in horn.
Insert horns and wipe any excess Aeropoxy from
surface. Horns should be vertical to surface
1/4”x1/4” balsa triangle stock is glued along fwd
side of live elevator hinge and stab T.E. spar for
added rigidity to hinge line. Check balsa for
length and proper fit. Glue may need grinding
slightly at ends. Sand off a bit of the 90° edge of
the balsa to achieve a better fit to stab T.E. spar.
Flex elevators up and glue balsa in place with
SLO-ZAP.
See stab cross section on plans to properly orient
triangle stock. CAUTION: Do not over flex the
elevator hinge, this could cause the top F/G skin
to tear away from the foam laminate.
Elevator linkage should be assembled next. Be
sure to use the correct threaded rod size. Solder
a threaded clevis to one end of each rod.Thread
Sullivan clevis to other end of rod.
Tape the elevator in the neutral position. Center
the servo arm to neutral. Adjust the control
linkage to this position.

BVM ® 2023 16 12/2023
STAB MOUNTING
Scuff outside of 4 aluminum stab inserts with
sanding board. Insert (4) 6-32x1-3/4” stab bolts into
tapered ends of inserts, plug other ends with bits of
modeling clay to prevent Aeropoxy from filling
inserts when installed in stab.
Proper depth of insert into stab leaves approx. 1/2”
of insert exposed. Just covering 2nd row of knurling.
Tapered end allows easy insertion into fin. Note
opening for servo leads, match to that in fin.
It is necessary to drill 1/16” vent holes in the
fore and aft arrow shafts in the stab. Drill
through one wall only of shafts. This allows air
to escape when alum inserts are glued in.
Sight through shaft, if open, one hole is
sufficient, if plugged in the middle drill two
holes, one each per servo pocket. Use a 6”
long 1/16” bit. Protect stab skin while working
❑Arrow shafts are built into stabs to
receive inserts. IMPORTANT -
Thoroughly scuff inside of arrow
shafts to better accept glue.
❑Insert Aeropoxy into arrow shaft ends.
Apply Aeropoxy to aluminum insert
then slide slowly into stab. Remove
once to check for areas not covered
with glue, then re-insert. Be sure to
leave 1/2” of insert outside stab end.
