Since there are many excellent choices of engines for this airplane, we can only provide a basic
reference for a typical installation. Use the following dimensional drawings in conjunction with
your engine’s outline specifications to determine the proper setup necessary for your particular
engine. Please carefully review all dimensions before proceeding.
For DA50-R users, we have prepared a very comprehensive guide on installing DA50-R in a
later section. Familiarize yourself with the general guide before skipping to the DA50-R section.
Warning:
Under no circumstances never disassemble, cut into, nor break up engine box structure to
adapt for your particular engine. Failure to comply will void manufacturer warranty.
Dimensional References – Engine Installation

The following procedures is a non-brand specific guide to install your particular engine. This by
no means is the ONLY way NOR does it apply to all engines across the board. This is simply
one user’s general approach, written for you information only.
General Guideline for Installation of Radial-Mount Engine:
Doc. No.# AW70-105-01, Rev. 3 Copy Right 2006, AirWild Hobbies, Inc. Page 8
1. Determine the full length of your engine, from
base of engine mount to the prop hub. Let’s call
this dimension X. For the purpose of discussion
we use DA50-R’s dimension for illustration.
2. Now refer to the “dimensional reference – engine
installation” in the previous section, take the
Diagonal Distance (170.25 mm) and subtract X
from it.
Y = 170.25mm – X
3. Dimension Y is the thickness of spacer you need to fabricate to position the engine for the
proper clearance. Use a 3/4” ~ 1” wooden dowel which you can easily find at your local
hardware supply, ie. Home Depot, and then cut to length.
STAND-OFF FABRICATION
Cut dowel to the desired length. Make sure they are all of even length. Use a drill press to do the next step.
Drill a center hole of the appropriate diameter for the engine mounting bolt to run through the dowel. Next,
saturate the through hole and two ends of the dowel with thin CA. Harden with CA Kicker. This will
prevent the dowel from splitting under pressure. Repeat same steps to fabricate the remaining pieces.
4. Next you need to locate and drill the mounting pattern for your radial-mount engine. A set
of offset center lines has been laser scored onto the front of firewall. Refer to your engine
manual in conjunction with the center line references to locate the bolt pattern. Drill and
mount your engine accordingly.
DA50-R Engine Installation Guide
1. Make sure your DA aluminum stand-offs is the standard-size, 2.5” set.
2. Fabricate four (4) 0.25” (6.35mm) thick spacers out of 5-layer, 0.25” thick plywood.
3. Install spacer between stand-off and fire wall.

For your convenience we have created a sheet of DA50-R mounting bolt pattern template to
simplify your work. Simply cut out the template, superimpose it onto the firewall and locate the
mounting holes that way.
Mounting Holes Located & Drilled DA Standoffs Installed
(0.25” plywood spacers not shown) DA50-R Installed (0.25” plywood spacers not shown)
Installing the DA ignition module is the next thing to do. The ideal place for ignition module is
on the bottom surface of the engine box, as shown in the illustration below
DA50-R Ignition Installation Guide
1. Turn the airplane upside down to have the bottom of the
engine box facing up.
2. Place ignition module in the middle of the surface. Mark
and cut two slots to be used for strapping down the ignition
module. We prefer using Velcro strip to for this application.
3. Apply thin CA to the perimeter of the slot. This will reduce
chances of plywood splitting. Harden with CA Kicker.
4. Use Velcro strip to secure ignition module as illustrated.
Cushion the module with a piece of foam.
5. Drill a hole through the bottom surface to route the battery
connector of the ignition module to the inside of the engine
box where the ignition battery will situate.
Doc. No.# AW70-105-01, Rev. 3 Copy Right 2006, AirWild Hobbies, Inc. Page 9

The block diagram below illustrates how we completed the rest of the ignition power distribution
setup. Refer to our “Suggested Component List” for the specifics on individual components.
6. Your ignition battery can be strapped down using the same
Velcro strip or you can use a second Velcro strip to secure
the ignition battery. Make sure to also cushion the ignition
battery pack.
7. Cutout for the ignition battery switch has been precut and is
located in front of former #2 as illustrated. Cutout is
dimensioned to fit a DSC Super Switch. Cut away Ultracote
to reveal cutout and mount switch accordingly.
8. An optical ignition kill switch is not required but highly
recommended for safety as it allows you to remotely turn off
engine in case of emergency, not to mention the fact that it
is also a convenience. Our preferred device is the SmartFly
Optical Kill Switch as it is extremely compact and proven
over the years to be very reliable, and also offers a
detachable and highly visible LED for status display of
ignition power.
Before mounting the optical kill switch you do have to make one modification; change
SmartFly Optical Kill Switch’s ignition side connector from a standard 3A rated servo
connector to a 10A-rating Anderson Power Poles (APP) connector provided in your
DA50-R ignition package. Unfortunately this is inevitable as there is no set standard for
interconnecting engine related devices in the RC hobby industry. Get your soldering iron out.
Find some heat shrink tubing and get started. Refer to photos below for BEFORE and AFTER.
Mount optical kill switch with a
double-sided foam tape. Stock SmartFly optical kill switch shown with a servo-type connector
for ignition.
Modified SmartFly optical kills
switch with an APP connector for
DA50 ignition.
When done, find a spot to mount your SmartFly optical ignition kill switch. Use adhesive back
foam tape or Velcro tapes to secure it. You are done with this part of installation.

Fuselage 1 Fuel Tank (20 oz.) (option) 1
Double Sided Velcro Strips (option)
By design fuel tank is located
on CG of the airplane. We
have designed in a plywood
fuel tank tray as illustrated in
the photo.
Set up the internal plumbing of your tank first. When ready, simply strap in your fuel tank to
the tank tray with two pieces of double-sided Velcro strip. Please note that there are two cross
members running length wise under the fuel tank tray for support. Be sure to route your Velcro
strips under the cross members. As a good practice always cushion your fuel tank with a piece
of high density foam; preferably on both top and bottom of the tank.
We also highly recommend using stainless steel twist ties to secure fuel line to copper tubing.
This will provide added security in preventing fuel line from slipping off copper tubing in hot
environment. Sullivan Product’s Twist-Tie Clamps (P/N #488) is a great choice for this
application which is available from AirWild Hobbies / AirWild Pilot Shop online.
Basic Setup of Fuel Delivery System
Most gasoline engines are equipped with a suction based
carburetor such as Walbro or Tilliston. Therefore your fuel tank
must be vented to provide one critical ingredient of this fuel
delivery system; atmospheric pressure. Illustration above
demonstrates a typical setup for fuel delivery.
Select gasoline compatible components to construct this basic
configuration. If you have purchased a hardware package from
AirWild, refer to the list below for component usage.
Fuel Tank 20-oz. tank with gasoline compatible stopper and internal
tubing Du-Bro DUB420
Fuel Tubing Gasoline compatible fuel tubing, cut to size Aerotrend

Adding an optional inlet filter to prevent contaminants from
entering fuel system. Highly recommended
Dynamite
DYN2006
Fuel Vent Simply run this fuel line out through the bottom of fuselage
Drill a hole in main landing gear plate to accomplish this
Throttle Servo Setup
Our preferred choice of throttle servo is a mini metal gear digital servo. It offers compact
footprint, light weight, good holding power and, most importantly, accurate movement to always
assure the most precise throttle setting.
Depending on the engine brand the engine throttle arm can situate either on the left or right
side of engine carburetor. To address this discrepancy our Extra 260 design allows you to
place throttle servo on the side of the throttle arm by using glue-in plywood mounting rails to
anchor the servo. Make frequent references to photos and illustration to complete the following
steps.
1. A plywood mounting rail consists of gluing two pieces of
45mm x 15mm x 2mm plywood together. You will find
provided in the kit four pieces of such plywood to make two
rails.
2. Once you have determined which side to install the throttle
servo, glue one mounting rail to the corner of the former
cutout using thin CA.
3. Position throttle servo so that one mounting flange rests on
the plywood mounting rail and slide the second rail under to
match up with the other mounting flange of the servo.
4. Glue the second rail in place. Since this rail is partially
suspended, use epoxy to glue it. When epoxy is completely
cured remount throttle servo.
5. Use Sullivan #580 CF push rod kit to fabricate throttle push rod. Cut both inner CF push
rod and outer housing to length. We recommend DuBro #181, Universal Ball Joint, for
end-point attachment to both throttle servo arm and engine throttle arm.

1. From the front edge of the fuselage side measure
33.5mm to its right. Draw a parallel line. Place a piece of
masking tape at where you intend to draw and then mark
your line on the masking tape. This will protect Ultracote
from being marred. Let’s call this line “Cowl Reference
Line”. Repeat this for the other side of fuselage.
2. Slide on cowl to the marked lines. Next, put the spinner
back plate onto the prop shaft and push it all the way up
against the prop hub. Check to see if you are satisfied
with the gap between spinner back plate and cowl.
Reposition cowl if necessary to obtain the desired gap
width.
The cowl overlaps the fuselage front by 33.5mm as shown.
This setting allows for approximately 2mm wide of gap between
the spinner back plate and the front of the cowl. With that in
mind follow the procedures below to get it mounted. With
engine installed (no muffler) slide on the cowl to position.
4. Locate the bag of plywood mounting block kit that’s
provided in the kit. It contains eight (8) pieces of 20mm x
10.5mm x 2mm plywood pieces. You will need to glue two
pieces back to back to make four 20mm x 10.5mm x 4mm
mounting blocks.
5. Refer to photo and glue these mounting blocks to locations
shown with 5-minute epoxy.
6. When cured install M3 blind nut provide for each mounting
block. Center point of the blind nut is about 5mm from the
edge of the fuselage.
7. Transfer blind nut locations to cowl. Drill holes in cowl to
accept M3 socket head screw for securing the cowl.

Install the steering spring according to the package instructions.
We’ve found that by adding a second anchoring point near the
coil spring will significantly improve the responsiveness of tail
wheel steering (see photo). As illustrated we used a piece of
scrap nylon strap and two sheet metal screws to accomplish this.

expose the slot. Slit the covering to the length of the slot.
3. Now use your Xactor blade and cut into the balsa core to
deepen the slot. Your goal is to create a through slot from
one side of the rudder to the other. Cut a little bit at a time

on each side and alternate side often. The cuts will
eventually meet in the middle of the balsa core and
complete the through slot. Remember to maintain the
cut perpendicular to the rudder surface
4. Trial fit the rudder horn into the slot for fitment. Loosen
slots (not length) if needed. Set up left and right rudder
horns according to the illustration below. You will need to
snip off approximately 4mm from the bottom of the horn in
order to get two horn to seat back to back.
5. Use a small amount of thin CA to tag glue the horns in place temporarily. This will allow
you to double check horn alignment before permanently sealing the horns. Break off tag-
glued joint if needed to realign horns.
6. When satisfied with horn alignment, glue both horns in place with thin CA. Saturate the
balsa core with thin CA and then harden it with CA Kicker. This step is very critical as it
dictates the bonding strength of the entire setup. If your slots are too loose, use gap-
filling medium CA to fill the voids.
Now we are ready to hinge rudder with the provided heavy-duty CA hinges. For this installation
we only require three (3) pieces of the CA hinges.
Draw CA hinge center line Install CA hinges Complete rudder hinging
7. Locate your CA hinges and draw a center line length wise on each CA hinge as shown.
8. CA hinge slots have all been precut for you in the rudder leading edge. Install all three
hinges up to the center line. Glue them in place with thin CA. Do not use CA Kicker for
this part of installation.
9. CA hinge slots have also been precut in the trailing edge of the vertical fin. Line up CA
hinges with the slots and slide rudder into place. Make sure that vertical fin and rudder are
budding against each other, thus eliminating any gap. Maintain a small gap between top of

vertical fin and the rudder counter-balance. Pivot the rudder to make sure there is no
hindrance in movement. When satisfied attach rudder permanently with thin CA.

Rudder control employs the pull-pull configuration where servo
is mounted inside the fuselage and linked to rudder control
horns via two parallel cables. Make frequent references to the
provided photos to guide you through the installation.
Servo Type: metal gear, 140 oz. in. output torque minimal,
digital preferable.
Servo Arm: aluminum full arm, 3” length
1. Drop in rudder servo and orient it so that the servo output
shaft is closer to the wing tube socket.
2. Install servo arm. Orient servo arm at 90 degrees to servo
case. We recommend hooking up servo to your receiver
and turn on your transmitter and receiver while doing so.
The default neutral point of every servo depends entirely
on the internal potentiometers of the particular transmitter
in use. Orient the servo arm at closely to a right angle as
possible and then use transmitter’s Sub-Trim function to
dial it in.
3. Construct a pair of pull-pull cables. We recommend the
following components which are included in our optional
hardware package. Build up one end of the cable first.
Then route the unassembled end through the cable exit
slot first before assembling the open end.

4. Hook up cables in parallel, to rudder servo arm and rudder control horns. Adjust cable
tension accordingly by dialing available threads in the Cable Attachment Fitting till
adequate cable tension.

Familiarize yourself with all the steps BEFORE proceeding.
1. Locate all eight CA hinges and draw a center line length wise
on each as shown.
2. There are four CA hinges per elevator. Hinge slots have all
been precut in the leading edge of the elevator and the trailing
edge of the stabilizer.
3. Starting first with elevator install all four hinges up to the center
line. Glue them in place with thin CA. Do not use CA Kicker
for this part of installation.
4. Line up elevator and stabilizer and slide CA hinges into the
trailing edge of the stabilizer. Make sure that is no hinge gap
between them. Pivot elevator to make sure there is no
hindrance in movement. When satisfied attach elevator and
stabilizer together with thin CA.
Installing elevator control horns is very similar to that of the rudder
horn installation with the exception that it takes two (2) EFP control
horns to build one elevator control horn assembly.
5. Refer to the photo on the right, locate two (2) 13mm x 2mm
slots covered under the purple Ultracote. These are the slots
for the elevator control horn assembly.
6. Use a Xacto blade to puncture the covering material and
expose the slots. Slit the covering to the length of the slot.
7. Now use your Xactor blade and cut into
the balsa core to deepen the slot. Your
goal is to create a deep slot that position
control horn’s pivot hole 1.25” below the
elevator hinge line. Remember to
maintain the cut perpendicular to the
rudder surface. Complete one horn at a
time.
8. Trial fit both control horns into the slots
for fitment. You will have to shorten the
EFP horns accordingly. Enlarge width of
the slot (not length) if needed. Align
horns to match illustration on the right.
Do not tag glue them yet.

9. Sandwich a 1/4 HD ball link between the two horns as
shown. Retain the ball link by threading the #4-40 SHCS
through both horns and ball link and lock in place with the
#4 lock nut. This keeps two horn parallel to each other and
creates a slop-free joint between control horns and ball link
which is critical to the precision of elevator movement.

10. Once again re-check horn alignment. When satisfied, glue
both horns in place with thin CA. Saturate the balsa core
with thin CA and then harden it with CA Kicker. This step
is very critical as it dictates the bonding strength of the entire setup. If your slots are
too loose, use gap-filling medium CA to fill the voids. When all is done, remove ball link.
11. Repeat 3~10 for the other stabilizer / elevator pair.

Elevator servo slot has been
precut to accept standard-size
servo. Illustration on the right
demonstrates our intended
configuration. Refer to illustration
often as we proceed. Let’s work
on the right elevator first. Repeat
for the left elevator.
Servo Type: metal gear, 100 oz. in. output torque minimal, digital servo preferable
Servo Arm: aluminum half arm, 1.25” length
5. Drop in elevator servo and orient it so that the servo output shaft is closer to the elevator
leading edge.
6. You will need to attach an extension lead to the servo in order to route lead to receiver.
Exact length of the extension depends on your receiver placement. If you are following
AirWild’s default setup, now is the time to attach an 18” extension to the servo. Use a
piece of dental floss to secure the interconnect.
7. Construct elevator push rod. We recommend the following
components which are included in our optional hardware
package;
AirWild Carbon Fiber Push Rod x1 AirWild #AW60-200-01
1/4 HD Ball Link x2 DuBro #899
8. Install servo arm. Orient servo arm at 90 degrees to servo
case. Hook up servo to receiver and turn on transmitter while performing this setup for
reason mentioned previously.
9. Hook up push rod to servo arm and EFP control horns. Adjust the turnbuckle push rod
until elevator is in neutral and servo arm is at 90 degrees to the servo body.
