WARNIN G

Some rubbing alcohols

may attack painted parts.

2. 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

3. 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.

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

in the bubble to relieve trapped air and reheat.

1. Remove the rear canopy before applying heat to

the covering. Excessive heat from covering irons

or heat guns can cause the canopy to melt or

warp. Take care not to apply excessive heat to

front section of canopy

6. Your model is covered with Ultracote™ cover-

ing. In case of repairs, the colors are:

Excalibur Scheme

Midnight Blue #885

Silver #881

Black #886

White #870

White/Blue Checkers

#933

5. Use your heat gun and iron with extreme cau-

tion. 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 unsightly gaps on the color lines.

The trim stripes are especially vulnerable to over

shrinking.

Tightening and re-shrinking the covering is now

complete

. However, this is a never ending

process and should be checked after each

flying session.

1. Go over all seams and color overlaps with

your sealing iron.

Note: Even if your models covering has no

wrinkles out of the box it is still very important

to go over all seams and overlaps to make cer-

tain they are sealed securely. This is espe-

cially 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

2. Use your covering iron to ensure all edges,

seams, and color overlaps are securely sealed.

3. If wrinkles occur near the hinge lines use a

covering iron with a sock on a low heat

setting. Be careful not to apply to much

heat to the fiberglass fairing covering the

hinge line. To much heat in this area can

cause the fiberglass to warp.

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.

Be careful not to apply to much

heat to the fiberglass fairing

covering the hinge line.

Aileron/Flap Servo Installation

1. Gather the aileron and flap servos, (8) servo

mounting screws, (4) servo mounting blocks, (2)

Wood screws to secure servo mounting blocks

(1) 6” Servo extension,(1) 24” Servo extension

(2) 1 1/4” Servo arms and (2) Aeroworks safety

clips as shown below.

Note: The ailerons and flaps have been pre-hinged

and glued to the wing panels and are ready

for flight. No other steps are necessary for

hinging.

WING ASSEMBLY

2. Remove the four screws holding the aileron

servo mounting plate to the wing as shown.

3. Mark the center of the servo arm exit slot as

shown. This will aid in aileron servo alignment.

4. Align the center of the servo arm to the refer-

ence mark made in the previous step. Place

servo mounting blocks next to servo and

mounting plate.

5. Place the servo on a flat surface as shown, this

will ensure correct placement of the servo

onto the blocks. Use a C-clamp to hold the

servo mounting blocks to the servo.

6. Drill holes for servo mounting screws. Either an

electric drill or a manual hand drill will work

well in these steps.

Note: We recom-

mend the Great

Planes Dead Center

tool Part #

GPM8130

7. Install servo with servo mounting screws. Re-

peat servo installation process for all aileron

and flap servos.

8. Use a pencil to mark the location of the servo

mounting blocks as shown. This will aid in

correctly positioning the mounting blocks

when gluing blocks to mounting plate.

9. Apply 30 minute epoxy to the mounting blocks

as shown, be careful not to get epoxy onto the

servo itself.

10. Use a C-clamp to hold the servo mounting

blocks to the servo mounting plate.

Note: Use two pieces of thin plywood to protect the

servo mounting plate and servo from being

damaged by the C-clamp.

11. Drill small hole through mounting plate and into

mounting blocks. Use provided mounting screws

to help secure the mounting block to the mount-

ing plate as shown.

12. Repeat process for the remaining 3 wing servos.

13. Layout the servos with servo extension at-

tached. One 24” extension will be used for the

aileron servo and one 6” extension will be used

for the flap servo. Use an Aeroworks Safety

Clip to ensure the plugs will not come apart

from vibration or light tension.

15. Pull the aileron servo lead through the root end

of the wing.

16. Pull the flap servo extension out the root end of

the wing using the same steps described for the

aileron extension.

Note: The aileron and flap leads will exit through a

hole in the top of the

wing, secure with tape

as shown.

17. Plug the servo into the receiver and turn on. En-

sure servo is centered and the servo arm is cen-

tered in the cutout. Take advantage of servo pro-

grammers and match boxes available today to

achieve best results. This will help keep servos

from binding and causing possible aileron flut-

ter.

Note: On metal geared servos use Loctite for all

Servo arm mounting screws.

14. Remove the balsa stick with the pull string from

the servo well and tie the pull string to the servo

lead as shown. Secure with tape so that the string

pulls from the front end of the connector

to as-

sist in drawing the servo wire through the

wing without hanging up inside the wing.

Aileron/Flap Control Linkage

Installation

1. Gather the aileron control linkage parts as shown

below. There are (2) 4-40 2 1/2”pushrods, (4) 4-40

ball link assemblies, (2) Flat washers (2) brass spac-

ers, (2) left and (2) right side control horns, (1) Ad-

justment wrench and (12) wood screws for each wing

panel.

18. Re-install the four screws holding the aileron

servo mounting plate to the wing as shown. Re-

peat process for remaining aileron and flap ser-

vos.

2. Assemble the 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. We rec-

ommend mounting the ball link in the center hole

of the control horn.

3. Align the control horns over the factory drilled

holes.

4. Use thick CA on each screw prior to

installing to lock screws in place

Note: CA glues have a fast drying time.

Remember to work quickly

5. Align the left and right sides of the control horns

to the mounting holes and secure using six wood

screws as shown.

7. Install ball link to servo arm as shown below.

Repeat process for other aileron and flap control

horn, and pushrod installation.

6. Correct installation of ball link, flat washer and

brass spacer to servo arm shown below.

Note: Flat washer prevents ball link from

coming off brass ball.

Flat

Washer

4-40 Bolt

Brass

Spacer

Lock Nut

9. Correct aileron pushrod installation shown be-

low, the servo arm should be 90 degrees to the

wing as shown.

8. Plug the servo into the receiver and turn radio

on. Ensure the servo trim and sub trim is cen-

tered. Adjust the length of the pushrod so that

the control surface is in the natural position.

10. Correct flap pushrod installation shown below,

the servo arm should be approximately 45 de-

grees to the wing as shown.

11. Finished wing panel assembly shown below.

12. It is recommended to remove the inner gear

doors at this time to ensure they will not be dam-

aged while checking landing gear operation.

14. Also check for proper operation of the retract-

able tail-wheel assembly and doors at this time.

Note: It is best to check air system at this time be-

fore going forward with any further assembly.

13. Attach the airlines to their respective connectors

and pump the system with air ( 100PSI MAX) .

This will be your last time to check for air leaks

in the retract system before the wings are joined.

Caution: Manually operate gear and gear door

valves to ensure the valves do not leak.

Take care not to crush inner gear doors

with gear when testing. We recommend

removing inner doors during testing

and assembly.
