INTRODUCTION

Your new 100cc-120cc

Ultimate 20-300 ARF-QB is a highly aerobatic airplane. It is ca-

pable of both precision and 3-D maneuvers. The aircraft builds easily, quickly, and precisely

due to its state of the art CAD design, LASER cut technology, and high quality included

hardware. We hope you enjoy building and flying your 100cc-120cc Ultimate 20-300

ARF-QB.

Great care has been taken in both the design and manufacturing of the 100cc-120cc Ulti-

mate 20-300

ARF QB to allow for the strongest and lightest construction possible. Only

the highest quality materials from the covering, paint, wood and hardware have been used in

the construction of this model.

The 100cc-120cc Ultimate 20-300 ARF-QB has been individually hand built, covered and

painted by trained and experienced craftsmen with over 25 years of manufacturing experi-

ence. Using CAD design, laser cut technology and jig-built assures accuracy in all stages of

production.

The 100cc-120cc Ultimate 20-300 ARF-QB is designed for gas engines in the 100cc-

120cc category. The DA-120cc engine is shown in the assembly instructions. The aircraft

was tested with the DA-120cc and has outstanding performance. The final choice of engine

is left up to the builder. A computer radio is recommended to allow the pilot to take advan-

tage of the full capabilities of this aerobatic aircraft.

IMPORTANT Please read through this assembly manual carefully, before starting the as-

sembly of your new model. Inventory and inspect all parts and hardware for any imperfec-

tions or damage. Notify Aeroworks immediately if there are missing or damaged parts

and do not proceed with the assembly.

WARNIN G

Some rubbing alcohols

may attack painted parts.

1. Open your kit slowly and take care not to dam-

age any parts of the kit. Remove all parts from

their plastic protective covers for inspection.

Before doing any assembly or installation of any

decals it is very important to re-shrink or re-

tighten the already applied covering. Due to the

shipping process, heat and humidity changes

from different climates, the covering may be-

come lose and wrinkle in the sun. If you take the

time to re-tighten the covering, you will be re-

warded with a long lasting beautifully covered

model.

TIGHTENING AND RE-SHRINKING THE COVERING

2. Using your covering iron with a soft sock, gently

apply pressure and rub in the covering. If any

bubbles occur, your iron may be to hot. Reduce

heat and work slowly.

3. If bubbles persist, use a small pin to punch holes

in the bubble to relieve trapped air and reheat.

4. Use your heat gun with extreme caution. Take

care not to apply too much heat to one area for

long periods of time. This may cause the trim

colors to over shrink and pull away leaving un-

sightly gaps on the color lines. The trim stripes

are especially vulnerable to over shrinking.

1. Your model is covered with Ultracote™ covering.

In case of repairs, the colors are:

Red/Yellow/Black Scheme

Black #874

Silver #881

True Red #866

Bright Yellow #872

Ultracote™ Colors

Yellow/Silver/Blue Scheme

Pearl Blue #845

Silver #881

Cub Yellow #884

White #870

1. Go over all seams and color overlaps with your

sealing iron.

Note: Even if your models covering has no wrin-

kles out of the box it is still very important to

go over all seams and overlaps to make certain

they are sealed securely. This is especially

important at the leading edges of the wings and

stabs. We recommend checking the covering

after each flying session.

CHECKING SEAMS AND COLOR OVERLAPS FOR GOOD SEAL

SEALING HINGE GAPS

2. Use covering iron to ensure all edges, seams,

and color overlaps are securely sealed.

3. Sealing hinge gaps. This is an optional step

but is recommended.

Cut strips of the supplied clear covering to fit

the hinge gaps. Use covering iron to seal the

clear covering snugly into the bottom of the

hinge lines as shown for air tight hinge seals.

Note: The clear covering does have a transparent

protective backing. This must be removed

prior to applying heat and to the surface.

IMPORTANT:

It is the responsibility of the purchaser /

operator to check the covering seams and

overlaps for security and a good seal.

Aeroworks is not responsible for failure of

covering seams or overlaps during flight.

Note: If covering continues to lift apply a small

amount of thin CA underneath the covering.

Then using a clean rag apply pressure to secure.

One of the most important tools in your

flight box is a roll of clear tape. This can be

used at the field for fast and easy repairs of

the covering. Then once you have finished

flying the covering can be permanently

repaired.

CHECKING HINGES FOR PROPER THROW

2. Evenly heat each hinge along the entire length of

the wing. This will allow the hinge glue to soften

and the hinge to move into it proper position.

Hold the surface at full deflection until the

hinges have cooled down and the glue has re-

hardened.

3. If the elevator hinges are tight follow the

same process as described for the wings.

Note: Once these steps have been completed

the hinges will throw to their full deflect-

tion.

IMPORTANT

1. If control surfaces will not throw to full deflec-

tion it may be necessary using a heat gun to

apply heat to the knuckle of each hinge. This

will allow the hinges to move freely.

1. Go over all seams and glue joints with thin CA,

this will ensure your model lasts for many sea-

sons to come.

Note: Even if you can visibly see glue on all glue

joints it is still recommended that the joints be

reglued. Due to changes in humidity during the

life of the aircraft glue joints can separate, it is

always recommended that the glue joints be

checked before each flying session.

CHECKING GLUE JOINTS

2. Use thin CA to reglue any accessible glue joint

as shown below.

1. Leave the canopy bolted to the airframe at all

times unless working on the inside of the fuse.

Due to high humidity levels during the building

and shipping process the canopy may warp when

not bolted to the airframe.

CANOPY/FRONT HATCH WARP PREVENTION

2. The front hatch should also be bolted to the air-

frame whenever possible.

Aileron Servo Installation

1. The ailerons have been pre-hinged and glued to

the wing panels and are ready for flight. No

other steps are necessary for hinging. Clear

Covering is supplied for sealing the hinge gaps if

desired. However, due to the precisely aligned

and minimal hinge gap this step is optional.

◊ 1 - Wing panel

◊ 1 - Aileron servo

◊ 1 - 1 1/4” Servo Arm

◊ 4 - Servo Mounting Screws (Micro Fastener

Part number STW0209 recommended)

◊ 1 - 12” servo extension

◊ 1 - Aeroworks Safety Clip

WING ASSEMBLY

2. Attach the 12” servo extension to the servo wire

and secure using an Aeroworks Safety Clip.

Minimum recommended servo:

181 in. oz. / Metal Geared / Digital

3. Remove the balsa stick with the pull string from

the servo well and tie the pull string to the servo

lead as shown.

4. Pull the servo lead through the root end of the

wing.

5. Install servo in servo well with the output shaft

toward the leading edge of the wing.

Aileron Control Linkage Installation

1. Gather the aileron control linkage parts as shown

below.

◊ 4 - 4-40 x 3” Pushrods-With carbon reinforce-

ment sleeves

◊ 8 - 4-40 Ball Link Assemblies

◊ 4 - Flat Washers

◊ 4 - Brass Spacers

◊ 4 - Left Side Control Horns

◊ 4 - Right Side Control Horns

◊ 24 - Wood Screws

◊ 1 - Adjustment Wrench

3. Correct installation of ball link, flat washer and

brass spacer to servo arm shown below.

2. Assemble pushrod and control horn

assembly as shown. The ball link goes

between the left and right sides of the control horn

sides and is secured with a nylon lock nut.

Improperly installed servo linkages can cause ser-

vos to strip and ailerons to flutter. Aileron flutter

can and will destroy your model instantly!

Note: Flat washer prevents ball link from

coming off brass ball.
