Thank you for purchasing the Lanier R/C Dart. We are sure you
will be happy with the quality of the kit and happy with the flying
characteristics of the Dart. Because of it’s light weight,the Dart will
fly exceptionally well on a standard .40 size motor. This makes the
Dart a perfect “first time” low wing airplane. The gentle flying char-
acteristics and good aerobatic ability make is a joy to fly.

Important Information:
Please inspect the plane before beginning to assemble to make sure you are happy with it. After assembly has begun you cannot return
the kit. If you find a problem before beginning to assemble the plane you must contact us, please do not return it to the dealer. Due to
temperature changes the plane may develop some wrinkles in the covering that you will need to remove with an iron. Be sure to seal
the edges down first so that you do not cause the covering to shrink and leave exposed areas of wood. The model is built light to ensure
good flight characteristics. With the power available from the new breed of engines, it is necessary to use throttle management in order
not to overstress the airframe. You must maintain good tight control linkage with no slop, good servos with plenty of power, and good
servo arms to protect against flutter. Sloppy linkage and over speeding the plane will cause flutter which is not covered in the warranty.
Lanier R/C is proud of the care and attention that goes into the manufacture of parts for its model kits. The company warrants that for
a period of 90 days, it will replace, at the buyers request, any parts or material shown to the company’s satisfaction to have been defec-
tive in workmanship or material at the time of purchase. No other warranty of any kind, expressed or implied, is made with respect to
the merchandise sold by the company. The buyer acknowledges and understands that he is purchasing only a component kit from which
the buyer will himself construct a finished flying model airplane. The company is neither the manufacturer of such a flying model air-
plane, nor a seller of it. The buyer hereby assumes the risk and all liability for personal or property damage or injury arising out of the
buyers use of the components or the finished flying model airplane, whenever any such damage or injury shall occur.
Any action brought forth against the company, based on the breach of the contract of sale to the buyer, or on any alleged warranty
there under, must be brought within 1year of the date of such sale, or there after be barred. This one year limitation is imposed by
agreement of the parties as permitted by the laws of the state of Georgia.

1. Start with one wing panel. Make sure all
the hinges are aligned and the aileron has
a 1/32” gap at the wing tip.
Insert a straight pin in the center of the
hinge so the hinges will be one half in the
wing and one half in the aileron.
Push the ailerons in place tight against the
trailing edge of the wing and remove the
pins.
Move the aileron to full deflection in one
direction (about 1/2”) and apply one drop
of thin CA glue to each hinge. Move the
aileron to full deflection in the other direc-
tion and apply one drop of thin CA on each
hinge on that side.
Give the hinge a minute to dry then apply
one more drop to each hinge on each
side.
2. You will need a 6” extension for the
aileron servo lead.Use tape on the plug to
make sure it does not come apart.
Use the string installed in the wing to pull
the servo lead down the wing and out the
hole on the top side.
3. Mount the servo using the hardware sup-
plied with the radio.The output arm should
be to the rear.

4. Locate the dihedral brace. Identify the
top side, it is straight, the bottom has a 1
degree angle
top is straight
Trial fit the dihedral brace in one wing half.
Now slide the other wing panel on the
dihedral brace.
5. When satisfied with fit and alignment, take
the wings apart.
Mix 3 oz. of 30 minute epoxy and apply a
liberal amount to the root of both wings,
both sides and the edges of the dihedral
brace, and into the slots of both wings.
Use a scrape piece of wood to work the
epoxy down into the slots in the wings.
6. Slide the dihedral brace into place.
Slide the other wing in place and use
masking tape to hold the wing together till
the epoxy cures.
Check the trailing edge of the wing and
use a pin to make sure it stays in perfect
alignment.
Lay the wing down on a flat surface till the
epoxy cures, don’t stand it on one tip. This
will cause the epoxy to run to one end.
7. When the epoxy is dry, locate the four metal
landing gear straps and the eight #2 x 1/2”
screws.
8. Insert the landing gear wire into the slot in
the wing.
Place one gear strap 1/2” in from the gear
leg and the other 1/2” in from the end of
the wire.
Drill a 1/16” hole at each location and
install the #2 screws.
Repeat for the other wing.

2. Measure the stab to make sure it is cen-
tered at the rear.Use a yard stick to meas-
ure from the rear corner of the stab to the
trailing edge of the wing at the fuselage..
Move stab until this measurement is the
same on both sides.
Sight the stab, fin, wing alignment from
the rear of the plane. The alignment can
be changed slightly by pushing up or
down on the stab tip. This is all that should
be needed, but if more is needed you can
sand the stab saddle till the alignment is
perfect.
3. Do the same with the fin.
When happy with the alignment, use a
marking pen and mark a line on the stab,
top and bottom and on both sides of the
fuselage.
Do the same to both sides of the fin.
1. With the wing mounted on the fuselage,
slide the stab into the slot in rear of fuse-
lage.
Slide the fin into place in the slot on the
top of fuselage.
9. Locate the wheels and four wheel collars.
Install a wheel collar on the inside, then

4. Remove stab and fin from fuselage and
using a razor blade, remove the covering
between the lines you just marked.
Cut about 1/8” inside your mark so bare
wood will not be exposed when glued in
place.
Caution: Cut carefully and cut only the covering,
don’t cut the balsa underneath as this
would weaken the stab and fin.

5. Using 30 minute epoxy, glue the stab and
fin in place using the marks made earlier
to align. Use masking tape to hold in place
if necessary. Check alignment and allow
epoxy to cure.
6. Locate the two elevator halves and insert
the CA hinges in the slots.
Use pins in the middle as we did with the
ailerons to keep the hinge centered.
Locate the hole for the elevator joiner wire
in each elevator.
Trial fit the elevators in place making sure
the hinges go all the way in and the joiner
wire fits all the way into the slot.
7. When satisfied with the fit, put some
epoxy in the elevator joiner hole and
install the elevators.
Push the elevators up against the pins,
then remove the pins and push the eleva-
tors flush against the trailing edge.

3. Insert the gear into the hole in the bottom
of the fuselage and place the steering arm
on the wire.
Be sure and place the steering arm far
enough away from the firewall so that it
does not jam against the firewall when full
right rudder is applied.(about 1/4”).
Note: It is a good idea to mark the location of the
set screw and remove the nose gear and
file a flat spot on the wire where the set
screw hits.
4. While working on the nose gear go ahead
and apply a drop of CA glue to each of the
nuts that hold the nose gear block in
place.
Locate the 2-56 pushrod and clevis and
attach to the steering arm.
Use a silicone keeper over the clevis.
Insert the 5/32” nylon tube over the
pushrod and let it lay in the bottom of the
tank compartment.
Engine Mounting
1. Locate the two nylon motor mounts, four
3mm engine mounting bolts and nylon
lock nuts, four 4mm bolts and washers
and four blind nuts.
The length of the cowl from the firewall to
the back of the spinner is 4.75”. If you use
a spinner that is flush on the back such as
the Tru-Turn, that will be the distance to
the prop hub. If you use a spinner such as
the Goldberg which is offset at the rear
you will need to add 1/4” to the length.

and nylon lock nuts.
1-13/16”
1-13/16”
3. Measure down from the top of the fuse-
lage 1-13/16” and draw a line across the
fuselage.This should be just at the bottom
of the cheek cowls.
4. Draw a line down the center of the firewall.
Measure over 1/8” to the left side of the
plane and make another line. This will be
the offset for right thrust.
Center you motor mounts on these marks
and mark the location of the mounting
holes.
Before drilling the holes check to make
sure your muffler will clear the bottom of
the fuselage.
5. Drill a 13/64” hole at each location. This is
the size of the shank on the blind nut, not
the bolt.
Using one of the bolts and washers, pull
each blind nut into place on the back of
the firewall.
6. Bolt the engine in place using two flat
washer under each mount on the left side.
Be sure and use thread lock on the bolts.

wall with the front edge flush with the fire-
wall..Two on top, two on the bottom.
2. Make sure the location you pick is not over
a balsa stringer, we want the screws to go
into the hardwood of the firewall.
Use a pencil and mark 1/8” back from the
edge of the firewall.
3. Mark the location of the top holes 1/8”
back from the firewall.
