Congratulations on your purchase of the Great Planes Giant Aeromaster
ARF! This classic Great Planes kit is now brought to life in Giant-Scale in an easy to build ARF form! For the latest technical updates or manual corrections to the Giant Aeromaster ARF visit the Great Planes web site at www.greatplanes.com.Open the “Airplanes” link, and then select the Giant Aeromaster ARF. If there is new technical information or changes to this model a “tech notice” box will appear in the upper left corner of the page.
We urge you to join the AMA (Academy of Model Aeronautics) and a local R/C club. The AMA is the governing body of model aviation and membership is required to fly at AMA clubs. Though joining the AMA provides many benefits, one of the primary reasons to join is liability protection. Coverage is not limited to flying at contests or on the club field.It ev en applies to flying at public demonstrations and air shows. Failure to comply with the Safety Code (excerpts printed in the back of the manual) may endanger insurance coverage. Additionally, training programs and instructors are available at AMA club sites to help you get started the right way. There are over 2,500 AMA chartered clubs across the countr y. Contact the AMA at the address or toll-free phone number below.
IMPORTANT!!! T w o of the most important things you can do to preserve the radio controlled aircraft hobby are to avoid flying near full-scale aircraft and avoid flying near or over groups of people.
1.Your Giant Aeromaster ARF should not be considered a toy, but rather a sophisticated, working model that functions very much like a full-size airplane. Because of its performance capabilities, the Giant Aeromaster ARF, if not assembled and operated correctly, could possibly cause injury to yourself or spectators and damage to property.

2. You must assemble the model according to the instructions. Do not alter or modify the model, as doing so
may result in an unsafe or unflyable model. In a few cases the instructions may differ slightly from the photos.In those instances the written instructions should be considered as correct.
3.You must take time to build straight, true and strong.
4. You must use an R/C radio system that is in first-class condition, and a correctly sized engine and components (fuel tank, wheels, etc.) throughout the building process.
5. You must correctly install all R/C and other components so that the model operates correctly on the ground and in the air.
6.You must check the operation of the model before every flight to insure that all equipment is operating and that the model has remained structurally sound. Be sure to check clevises or other connectors often and replace them if they show any signs of wear or fatigue.
7. If you are not an experienced pilot or have not flown this type of model before, we recommend that you get the assistance of an experienced pilot in your R/C club for your first flights.If you’ re not a member of a club , y our local hobb y shop has information about clubs in your area whose membership includes experienced pilots.
8.While this kit has been flight tested to exceed normal use, if the plane will be used for extremely high-stress flying, such as racing, or if an engine larger than one in the recommended range is used, the modeler is responsible for taking steps to reinforce the high-stress points and/or substituting hardware more suitable for the increased stress.
9. WARNING: The cowl, wheel pants and wing struts included in this kit are made of fiberglass, the fibers of which may cause eye, skin and respiratory tract irritation. Never blow into a part (wheel pant, cowl) to remove fiberglass dust, as the dust will blow back into your eyes.Always wear safety goggles, a particle mask and rubber gloves when grinding, drilling and sanding fiberglass parts. Vacuum the parts and the work area thoroughly after working with fiberglass parts.
Remember:Take your time and follow the instructions to end up with a well-built model that is straight and true.
This is a partial list of items required to finish the Giant Aeromaster ARF that may require planning or decision making before starting to build.Order numbers are provided in parentheses.
The Giant Aeromaster ARF has different setup options for the ailerons and elevator functions that will alter the radio gear required for completion. Below is a quick reference of the BASIC radio gear needed for each setup.There may be many other options depending on your radio of choice.
Note: If you are using a gas engine instead of glow powered for this model, we recommend using a PCM dual conv ersion receiver to help alleviate interference.
Option 1:Two wing servos.This option will require the following:
4-channel radioSix standard size servos capable of at least 70 oz-in of
torque, such as Futaba®S9202 (FUTM0090) or S3050 Digital servos (FUTM0300)
Reversing Y-harness for elevator servos (FUTM4150)
for elevators
Dual servo extension for bottom wing aileron
servos (FUTM4130)
Two 20" [508mm] minimum length servo extensions
(FUTM4147 for bottom wing servos)
FM or PCM Dual Conversion receiver
Option 2: Four Wing Servos. This option will require the following in addition to or upgraded from the above items:
6-channel computerized radio (mixing features will
be required)
Two additional servos, standard size capable of at least
50 oz-in of torque for top wing servos, such as Futaba S9001 (FUTM0075)
Two 20" [508mm] minimum length servo extensions
(FUTM4147 for top wing servos)
Y-Harness for the top wing aileron servos (HCAM2751
for Futaba)
Minimum 6-channel FM or PCM receiver for basic setup
Option 3: All-Out Computerized Option. This is for those with advanced mixing function radio setups.
9-channel computerized radio with 9-channel dual
conversion FM or PCM RX
Eight servos total, (4-aileron, 2-elevators, 1-rudder,
1-throttle)
Six 20" [508mm] minimum length servo extensions for
top and bottom wing servos (FUTM4147)
• two connected to top wing aileron servo leads to exit wing
Radio Equipment
DECISIONS YOU MUST MAKE
We, as the kit manufacturer, provide you with a top quality, thoroughly tested kit and instructions, but ultimately the quality and flyability of your finished model depends on how you build it; therefore, we cannot in any way guarantee the performance of your completed model, and no representations are expressed or implied as to the performance or safety of your completed model.

• two connected to separate channels on RX to connect to top wing servo leads
• two connected to bottom wing aileron servo leads to exit wing
Two 6" [153mm] servo extensions for connecting the
bottom aileron servos to the RX
Whichever option you choose, a battery pack with a minimum of 1,000mAh should also be used for the RX! For a gas model, a battery pack with a minimum 600mAh rating should be used for the ignition. When flying giant-scale models such as this, you should ALWAYS check the battery condition before each flight.
The recommended engine size range for the Giant Aeromaster ARF is specified on the cover of this manual.All engines within the specified range will power this model well. Never fly the Giant Aeromaster ARF with an engine larger than one in the specified range because it has not been designed or tested for larger engines. Powered by a two-stroke glow engine such as the O.S.®BGX-1 3500 (OSMG0352), the Giant Aeromaster ARF performs like any 60-size sport plane with the added stability and durability of any well-designed giant plane.If flying the Giant Aeromaster ARF with a glow engine, the kit includes a plywood engine mount plate to facilitate the use of a 1.20 to 1.60 adjustable engine mount.
If you haven’t yet built a model with a gas engine, but are considering using one, two of the benefits are fuel economy (not only is gas cheaper than glow fuel, but gas engines typically burn less fuel as well) and considerably cleaner exhaust residue.Most gas engines, however , are heavier than glow engines and require premixing gas and oil.
Here are the order numbers for O.S. MAX, SuperTigre
®
and Fuji-Imvac™engines:
O.S. 1.60 FX 1.60 cu in 2-Stroke Glow Engine (OSMG0661)
SuperTigre G-3250 1.98 cu in 2-Stroke Glow Engine (SUPG0268)
O.S. BGX-1 3500 2.13 cu in 2-Stroke Glow Engine (OSMG0352)
Fuji-Imvac BT-43EI Electric Ignition Gas Engine (FJIG0143)
Per the IMAA Safety Code, magneto spark-ignition engines must have a coil-grounding switch on the aircraft to stop the engine and prevent accidental starting.The switch must be operated manually (without the use of the transmitter) and be accessible by the pilot and assistant. For use with the Fuji-Imvac engine shown, the manually-operated switch was made from a .3 Amp slide switch, 16-gauge wire and a covered, crimp-on connector purchased at the local Radio Shack®. Slightly different hardware may be required if using a different spark-ignition engine. All of the components required are available at any hardware or home­improvement store.
In addition to the items listed in the
“Decisions Y ou Must
Make”
section, following is the list of hardware and accessories required to finish the Giant Aeromaster ARF. Order numbers are provided in parentheses.

When you see the term
test fit
in the instructions, it means that you should first position the part on the assembly without using any glue, and then slightly modify or
custom fit
the part as necessar y for the best fit.
Whenever the term
glue
is written you should rely upon your experience to decide what type of glue to use.When a specific type of adhesive works best for that step, the instructions will make a recommendation.
Whenever just
epoxy
is specified you may use either 30-minute (or 45-minute) epoxy or 6-minute epoxy. When 30-minute epoxy is specified it is highly recommended that you use only 30-minute (or 45-minute) epoxy, because you will need the working time and/or the additional strength.
Harden all holes with thin CA after drilling and inserting screws.
Photos

are placed before the step they refer to. Frequently you can study photos in following steps to get another view of the same parts.
The Giant Aeromaster ARF is factory-covered with Top Flite®MonoKote®film. Should repairs ever be required, MonoKote can be patched with additional MonoKote purchased separately. MonoKote is packaged in six-foot rolls, but some hobby shops also sell it by the foot. If only a small piece of MonoKote is needed for a minor patch, perhaps a fellow modeler would giv e you some .MonoKote is applied with a model airplane covering iron, but in an emergency a regular iron could be used.A roll of MonoKote includes full instructions for application. Following are the colors used on this model and order numbers for six foot rolls.
True Red – TOPQ0227 Jet White – TOPQ0204

1. If you have not done so already, remove the major
parts of the kit from the box (wings, fuselage, cowl, tail parts, etc.) and inspect them for damage. Be sure to label the ailerons in some way to remind you of which wing panel they belong to.If any parts are damaged or missing, contact Product Support at the address or telephone number listed on page 7.
2. Remove the masking tape and separate the ailerons
from the wing, the elevators from the stab, and the rudder from the fin. Use a covering iron with a covering sock on high heat to tighten the model’s cov ering if necessary. Apply pressure over sheeted areas to thoroughly bond the covering to the wood.
❏ ❏ 1. Locate the two bottom wing panels.
❏ ❏ 2. There are four holes drilled in each wing panel to
accept the hinges.Test fit each hinge in the wing.
❏ ❏ 3.Test fit the aileron to the wing. ❏ ❏ 4. Remove the hinges from the wing and aileron and
set them aside.
❏ ❏ 5. Mix up some 30-minute epoxy and Microballoons
(if using mixing cups, approximately 1/4 oz. [7g] of Microballoons added to 1/4 oz. [7g] of mixed epoxy is recommended). Use a toothpick to thoroughly apply the mixture in the holes in the wing and aileron. Use the toothpick to get the epoxy out of the outer edge of the opening of the holes in the aileron so it doesn’t get into the hinge pins.Wipe away any epoxy around the outside of the holes with a paper towel.

❏ ❏ 6.Before inserting the hinge in the hole, apply a drop of
oil to the hinge.This will serve to smooth the operation of the hinge and also help prevent epoxy from binding the hinge.
❏ ❏ 7. Reattach the aileron. There should be a gap just
small enough to see through when the aileron is properly attached as shown in the second photo.Caution: DO NOT move the aileron until the epoxy has cured completely. Doing so may work epoxy into the hinge and cause it to bind! Use masking tape to hold the aileron in place until the epoxy has completely cured.
8.Repeat steps 2-7 for the other top and bottom wing panels.
Note: There are two options for aileron installation on the Giant Aeromaster ARF. One option is to use two bottom aileron servos to drive all four ailerons.The second option is to install an aileron servo for each of the four ailerons.You will repeat the following steps f or the top wing if you choose to use four aileron servos. If you choose to use the two servo option, later in the manual after the wings are mounted, you will join the two ailerons on each side.
❏ ❏ 1. Locate the aileron servo bay in the bottom of the
wing panel. Remove the covering from the opening using a sharp hobby knife.Seal down the edges of the opening with a sealing iron after cutting.
❏ ❏ 2. Attach a 36" [914mm] ser vo extension to the aileron
servo and seal the connection using 3/8" [9.5mm] heat­shrink tubing as shown (not included).
❏ ❏ 3. Inside the cutout for the servo there is a length of
string taped to the interior of the wing. Carefully pull this string up and out of the aileron servo bay.

❏ ❏ 4. Securely attach the string to the end of the servo
lead.The other end of the string is attached with tape on the inside of the wing near the root.Pull this end of the string up and through the small 1/2" [13mm] hole in the top of the wing panel.You will need to remove the covering from this small hole using a sharp hobby knife.
❏ ❏ 5. Pull the string to route the servo lead through the
wing and out the small hole in the top of the wing.
❏ ❏ 6.Attach the servo lead to the wing panel with a small
piece of masking tape.
❏ ❏ 7. Mount the ser vo to the wing using the hardware
provided by your manufacturer. The output shaft spline will face the LE of the wing.Remove the servo mounting screws after installing the servo and harden the screw holes by wicking some thin CA into them and allowing it to harden. Then reinstall the servo mounting screws.
8. Repeat steps 1 to 7 for the other wing panel.9. If using a four servo setup, you will repeat steps 1 to
7 above for the top wing. The 1/2" [13mm] holes for the servo leads to exit the bottom of the top wing are located further in from the center of the wing than as on the bottom wing. Remove the covering from these holes only if using the aileron servos in the top wing.
1. Locate the large wing joiners for the bottom wing.
These will be the large rectangular joiner and the larger of the two small angled joiners.Measure and mark the centers of the joiners.
2. Test fit the wing joiners into one wing panel. Sand the
wing joiners as needed for a good fit.
3. Slide the other wing panel onto the wing joiners. Sand
the wing joiners as needed for a good fit. The wing roots should be flush with little or no gap present.
4. Separate the wing panels and remove the wing joiners.5. Mix a large batch of 30-minute epoxy (if using mixing
cups, 1 oz. [28g] of mixed epoxy is a good amount.)
6.
Thoroughly
coat the inside of the wing joiner pockets
and wing roots with 30-minute epoxy.
7. Apply epoxy to each of the wing joiners and insert
them into the pockets in one wing panel.
