Assembly Notes and Historical Documentation

First Things First...
We want to thank you for your purchase of this fine radio control airplane kit. This airplane
goes together quickly, flies great and should provide you with many satisfying flights. One
point that we want to make is...if you have never built and flown a radio control airplane
before, do not attempt to build and fly this model without the help of an experienced
radio control airplane builder and pilot. This model airplane is not a toy and serious
injuries or damage to property can occur if you try to fly it without any help!!!
Before We Begin...
First, check all of the parts and tighten up any loose covering with a heat gun. Read the
assembly directions and familiarize yourself with the photos and assembly process.
Check that you have all items needed to complete the kit.
Let’s Go! Landing gear and Tail Feathers...
Assemble the main landing gear and mount to the fuselage. Install the tail feathers to
the fuselage. Pretty simple, just bolt the horizontal stabilizer to the fuse, insert the vertical
stabilizer into the top of the horizontal stabilizer and rear end of the fuse and bolt into place.
Next, mount the tail wheel assembly to the rear of the fuselage.
Wings...
First, mount the cabanes to the fuselage and the top wing center section to the cabanes.
Assemble and attach the cabane flying wires to the fuselage and top wing center section.
Next, attach all of the flying wire brackets to the wings and mount the four struts to the wings.
Slide the right side wing assemble into the fuselage and prop the outer end up. Bolt the flying
wire brackets to the fuselage and attach the flying wires to the wings and fuselage.
Follow the same instructions to attach the left wing assembly to the fuselage.
airplane over and mount the plates to the bottom of the fuse that holds
the rear dowels of the bottom wing in place. Turn the airplane over and adjust the flying
wires on the wings. Remove the wings from the fuselage.
Carefully, turn the

Final Assembly...
Install the control surfaces in place and install your radio. Mount the engine, throttle linkage,
fuel tank and fit the cowl to the fuselage. Now would be a good time to install the wheels
to the landing gear and then attach the wings to the fuselage. Check that the control surfaces
are moving in the correct direction. Check and make sure that the airplane is balanced correctly
and adjust as needed.
Flying!!!
If you have never flown a radio controlled model before, do not attempt to fly this
airplane by yourself. Get the help of an experienced pilot! If you do not know any,
get in touch with your local radio control airplane club for assistance!!!
Check that everything is attached properly and that the control surfaces are moving in the
correct directions. Also, check the balance one more time before flying. Once you are
satisfied, start up the engine, taxi out onto the runway and get it into the air! The Tiger Moth
is a great flying airplane and you will find that it is a very gentle flying airplane, also.
Finally...
We hope that you have enjoyed assembling the DeHavilland Tiger Moth and that you will
have many great flights with it. If you have any questions or suggestions,
we would like to hear from you.
Smooth Landings!!!

When is an ARF (Almost Ready to Fly) not an ARF? Maybe when it is an
‘ARF (Almost Ready to FINISH)! Arizona Models have filled a niche in the
hobby in the area of WWI (and earlier). They have also managed to explore
the area of various scale planes that will not all look like. The ‘kits’ are
complete in that all the building is done, hardware supplied, and the airframe
is covered – but that is where it stops.
The modeler has a range of option(s) from simply throwing on some paint,
install equipment and be done with it – OR – using the basic scale airframe
and detailing the model to accurately replicate the full-scale version.
First Impressions
The Tiger Moth arrived undamaged and covered in a white (unpainted) cloth
fabric covering. The covering was expertly attached and very few bubbles
appeared during the assembly/flying period. The horizontal and vertical
stabilizers were constructed from open frame balsawood and can be
mounted permanently or removable.
Four wing panels, fuselage and a nice fiberglass cowling rounded out the
airframe. Also included in the kit were a couple of packages of hardware
(struts, landing gear, etc), wheels and a package consisting of two scale
cockpits.
It was at this point the plane cried out in a loud and clear voice, “Detail ME”,
so with that in mind, I did some research and tried to incorporate as many
features from the full-scale on my model.
Assembly:
The first activity was installing the aileron servos in the bottom wing. After the
hinges were glued in place, a standard Airtronics servo was installed on the
plastic aileron hatches. The ailerons required a 12” extension to reach the
wing root area.
Then progress shifted to the top wing’s center section. This has to be
installed correctly or the top and bottom wings will not align correctly. The
supplied hardware made this process simple.
1/4 ARF Setup By Jerry Festa

Once the wing’s center section was completed, the tail feathers were
attached. I choose to permanently secure both horizontal and vertical. Both
slid into position correctly and accurately.
Wing(s)
Now the fun started – the bottom holds UP the top wing wing but the wire
rigging holds UP the bottom wing from it to the center section – did you follow
that? Anyway the procedure was to mount the bottom wing and secure it with
6-32 bolts and blind nuts to the fuselage. Using some books, the wing is held
at a slight dihedral angle and some rigging wire was connected from the wing
to the top wing’s center section.
The two wing struts were mounted on the bottom wing and the top wing
attached to both the center section and the wing struts. Now all the rigging
cables were made from Du-Bro’s 4-40 pull-pull cables and their ¼ scale
turnbuckles.
Engine:
A Saito 91 was used and proved only adequate. A better choice would have
been a Saito 100; nonetheless, the plane flew VERY scale-like (meaning
slow and almost under powered – just like the full-scale). On another
identical plane an OS .91 two stroke was used and exhibited a higher rate of
climb.
With the Saito .91 mounted in front of a Du-Bro 16 oz. tank, there was plenty
of room for a Du-Bro Remote Glow Extension, exiting on the dashboard in
the front cockpit.
Radio installation:
The full-scale version exhibited some unique cabling arrangements. The easy
road would have been to mount the servos for rudder and elevator in the fuse
and use Sullivan’s Ny-Rod to control those surfaces. But NO…. I had to do it
the hard way and duplicate the full-scale method.
The rudder servo was used to drive two bell cranks, and they exited the
fuselage over the bottom wing. From each of those arms, the rudder was
connected with 4-40 cable. Two elevator servos were also located on the
plywood tray that held the rudder servo. Again, Du-Bro Pull-Pull arrangement
was utilized with each servo driving one half of the elevators.

Talk about looking cool! And more shocking was the fact that it worked! About
the only flaw appears in the rudder arrangement.
The pull of the cable will surely do the job, but the other cable goes slack
because of the geometry of having a larger ‘bell crank’ than control horns. No
big deal.
The receiver and battery were located as far forward in the spacious fuselage
as possible. The “Y” connector used for the ailerons was placed in position
under the servo tray.
The undercarriage simply bolts on to the fuselage. The 5” Du-Bro tires round
out the landing gear with one exception – the wheel outer hubs got the
‘DeHavillian’ decal to finish off the wheels.
Fine Touches:
As mentioned earlier, some additional procedures were utilized. The most
obvious addition was the ‘ribbed’ effect done to the Tiger Moth’s fuel tank,
which (on the full-scale) was in the top wing’s center section. Some plastic
from Evergreen Scale Models was gently heated and glued to the center
section. The part used was # 4544 Board & Batten. Also the regular nylon
control horns were replaced with Sullivan’s to give a more scale appearance.
The two cockpits were finished and installed according to the instructions,
which came with them. Some of the detail supplied in this kit was amazing. If
so desired, some of the instrument needles could actually move! I’m still
looking for a very small compass
Departing from the scale appearance slightly, the front cockpit received the
“On/Off” switch in addition to the remote glow igniter mentioned earlier.
Because they are black, and are mounted on the dashboard, they flow with
the scene almost not noticed.
