We've all stopped on the side of the road to watch cropdusters at work. Practical
aerobatics combined with real precision flying makes it very cool to see. The 65" Turbo
Duster captures the spirit of the latest-technology full-scale dusters.
The Turbo Duster ARF is quick to build, strong, light, and is very high-performance. In
addition to all of the low-level scale maneuvers, you can take the Duster to the e tremes of
high-energy tumbling aerobatics, or you can fly it as a gentle and predictable sport
airplane – it's up to you!
The Duster uses the same simple, reliable equipment as the E treme Flight 60" series of
aerobatic aircraft, and adds two flap servos. The flaps can (and should!) be programmed
for a variety of fun modes, to give an e tra-wide flight envelope. The Duster is going to
delight you with its many talents – so let's get started!
Items needed for completion:
Masking tape.
Hobby knife with #11 blades.
Thin and medium CA. We highly recommend Mercury M5T thin and M100XF

Tips for Success:
1. Before starting assembly, take a few minutes to read the entire instruction manual
to familiarize yourself with the assembly process.
2. Please take a few minutes and go over all the seams on the aircraft with a covering
iron on a medium heat setting. Also, due to climate changes, wrinkles may develop
in the covering. These are easily removed with a little bit of heat. Use a 100%
cotton tee-shirt and your heat gun and heat the covering while gently rubbing the
covering onto the wood with the t-shirt. Be careful not to use too much heat as the
covering may shrink too much and begin to lift at the edges. Take your time, and a
beautiful, paint-like finish is attainable.
3. Apply a bead of Pacer Formula 560 Canopy Glue at the intersection of the plastic
canopy and its wooden frame.
4. Take a few minutes and apply CA to high stress areas such as servo mounting trays,
landing gear mounts, anti-rotation pins, and motor bo joints.
5. By the time your aircraft arrives at your door step, it will have been handled by a lot
of people. Occasionally, there are small dings or imperfections on some of the
surfaces. An effective method to restore these imperfections to original condition is
to use a very fine tipped hypodermic needle and inject a drop of water under the
covering material and into the ding in the wood. Apply heat to the area with a
sealing iron and the imperfection will disappear. Deeper marks may require that
this process be repeated a couple of times to achieve the desired result, but you will
be surprised at how well this technique works.
6. Use a high quality epo y for installing the composite control horns. We highly
recommend the new Mercury Adhesives 30 minute Epo y or Pacer Z-po y. We are
very pleased with the results and ease of application and cleanup of these products.
7. When applying decals, first clean the area where the decal will be applied with
alcohol. Mist the area lightly with Winde or Rapid Tack before applying the decal
which will allow you to properly position it, and then use a rubber squeegee to push
all of the liquid from under the decal. This will result in very few air pockets
trapped under the decal.
8. Take the time to properly balance and trim your aircraft and set up rates and
e ponential values. Your flying e perience will be greatly enhanced once your plane
is properly dialed in.

Let's begin!
1. Locate the 2 wing panels as well as the composite aileron and flap control horns
and linkage hardware.
2. Use a soldering iron or sharp hobby blade to remove the covering over the slots
for the aileron and flap horns. Make sure you are doing this on the bottom of the
wing! Test-fit the horns – NO GLUE YET.
5

3. Once you are satisfied with the fit of the horns, remove them. Use sandpaper to scuff
the portion of the horn that will be inserted into the aileron or flap.
4. Apply 30 minute epo y to the slot in the aileron and the scuffed potion of the
control horn that will insert into the aileron or flap. Use a zip tie or toothpick to
ensure the slot is completely filled with epo y. Install the aileron horn into the
aileron slot and wipe away any e cess epo y with a paper towel or cloth soaked
with denatured alcohol. Allow to dry.
6

5. Remove the aileron and flap from the wing to ensure all hinges are centered
between the wing and aileron. One way to ensure the hinges are centered is to fold
them in half and re-install into the aileron using the crease as a reference point.
6. Slide the wings on to the fuselage and check the fit of the flaps. Make sure you can
deflect the flaps up without contacting the fuselage. Slide the flaps and ailerons as
necessary for clearance.
7

7. Glue the hinges using several drops of thin CA on each hinge. Make sure your
thin CA is reasonably fresh.
18. Attach an 8-12” servo e tension to the aileron servo and secure with a lock or heat
shrink tubing. Use the manufacturer supplied mounting hardware to install the servo
with the output shaft toward the leading edge of the wing. Electronically center the
servos. Use 4 identical length arms on the flaps and ailerons.
8

12. Locate 4 of the short threaded metal pushrods and 8 ball links along with 8 2mm
screws, nuts and washers. Thread the ball links onto each end of the pushrods and
secure to the servo arm and to the control horn as shown in the picture below.
Remember to use Loctite on all nuts. Repeat this process for the other wing half.
Fuselage Assembly

13. Locate the carbon fiber landing gear and secure the landing gear to the fuselage
by inserting the 3mm bolt into a washer, through the carbon fiber gear and into the
pre-installed blind nuts in the fuselage. Make sure to use a drop of blue Loctite on
each bolt to prevent them from backing out. Note the LG has a tapered edge and a
straight edge; make sure the straight edge faces the front of the fuse.
14. Locate the 2 a les, 2 locking nuts, 2 wheels, 2 wheel collars and 2 wheel pants.
Place the wheel on the a el and secure with the wheel collar. Secure the a le to the
carbon gear with the locking nut.
10

15. Remove the covering over the cooling outlet in the bottom of the fuselage as
shown.
16. Locate the rudder. Install, checking to be sure the hinges are centered as on the
wings.
17. Use several drops of thin CA on each rudder hinge.
11

18. Install the tailwheel as shown, bending the aluminum tiller arm to fit the rudder.
The wood screw in the rudder is left slightly loose so the tiller arm can easily swing.
19. Locate the slot for the rudder horn as shown, remove the covering with a soldering
iron or hobby knife.
12

20. Prepare the horn with sandpaper as you did for the wing, and install the rudder
horn with 30-minute epo y as shown.
13

21. Attach a 24" servo wire e tension to your rudder servo, using a lock or heat-shrink
tubing, route the wire through the fuselage, and install your rudder servo as shown.
22. Install the rudder pushrod as shown. Use Loctite on the nuts.
14

23. Turn the elevator upside down and backwards, and slide through the horizontal
stab cutout in the fuselage as shown.
15

24. Slide the horizontal stabilizer into the slot, slide the elevator into position on its
hinges, but do not glue yet.
25. Install the carbon fiber wing tube into the fuselage and use a tape measure as
shown to make sure the horizontal stabilizer is straight to the fuselage and perfectly
16

equal side-to-side. Measure on each side form the elevator hinge line to the wing
tube. The measurements should be e actly the same.
26. Once satisfied with the alignment, glue the horizontal stab in place by applying CA
along the joint between the stab and fuse. Make sure to apply CA to the top and bottom
17

of the stab, being careful not to get CA on the covering. NOTE: The stab on the Turbo
Duster is long in span. The covering is an important part of the structure of the stab.
DO NOT cut the covering. Thin CA will adhere to the covering material very well.
27. Align the elevator perfectly, fle it to make sure it moves easily 45 degrees up and
45 degrees down, and glue with several drops of thin CA per hinge.
28. Locate the slot for the elevator horn, remove the covering over the slot with a
soldering iron or hobby knife as shown.
18

29. Attach a 24" e tension to the elevator servo, thread the wire through the aircraft,
install the servo, horn, and pushrod as you have for the other control surfaces, as
shown.
30. Ne t prepare the Torque outrunner motor for mounting.
19

First, slide the provided collar over the motor shaft and secure in place with the set
screw. Place a drop of blue Loctite on the threads of the set screw so that it will not
back out.
34. Ne t, secure the radial mount to the motor using the provided short Phillip's head
machine screws. Again be sure to use a drop of blue Loctite on each screw.
