SAFETY NOTES

SAFETY NOTESSAFETY NOTES

SAFETY NOTES

 Before assembling and flying this model, read carefully any instructions and warnings of other

manufacturers for all the products you installed or used on your model, especially radio equipment and power source.

 Check thoroughly before every flight that the airplanes’ components are in good shape and

functioning properly. If you find a fault do not fly the model until you have corrected the problem.

 Radio interference caused by unknown sources can occur at any time without notice. In such a

case, your model will be uncontrollable and completely unpredictable. Make sure to perform a range check before every flight. If you detect a control problem or interference during a flight, immediately land the model to prevent a potential accident.

 Youngsters should only be allowed to assemble and fly these models under the instruction and

supervision of an experienced adult.

 Do not operate this model in a confined area.

 Do not stand in line with, or in front of a spinning propeller and never touch it with any object.

IMPORTANT: PRIOR TO ANY ASSEMBLY

Please Note: after removing kit from shipping box, lay each piece flat on a hard surface, this will allow the airframe to straighten out if lightly bent from shipping. Do not worry since EPP is very pliable and can be bent back if out of shape.

on your building technique you may not need everything indicated – and/or – you may find that other tools available to yourself may be of benefit to your Build.

It is also recommended that you have a flat building

surface, one that will accept stick pins and push pins.

An Acrostic Ceiling panel from your local hardware store fits this bill nicely, and will lay flat on your work table. Over size / long push pins are available at your local craft store. These two items are by no means required, but will aid in the building process, and can be used for future projects.

THE BUILD

THE BUILDTHE BUILD

THE BUILD

CONSTRUCTION METHODS:

Building surface should be at least 2ft x 4ft and flat. Weights or some small heavy objects will be handy for holding things in place during the time glue is setting.

Welders glue is used for FOAM TO FOAM joints. Thin and Medium CA are used on the PLASTIC TO FOAM and CARBON TO FOAM joints.

When using the Welders glue for a butt joint, apply a thin film to each surface, allow to sit for approx five minutes and then assemble. Note that this method will create a nearly instant bond, so locate carefully when bringing the two pieces together. If alignment is necessary or a slip joint, do not allow the glue to tack up, simple apply and join immediately, you will have several minutes to locate the

two parts before the glue sets up. In most cases the parts being glued can be handled with care in 30 minutes, full cure is approx 24 hours.

Locate the hinged items as shown above, bend them back

onto each other as s

hown and let set for an hour or so. This

process will help to loosen up the movement of the control

surface, and is necessary to prevent servo damage.

Gluing the snap links onto the ends of the controls rods is

important to do at this time... the glue will need to cure for

at least 24 hours in order to achieve it's full strength.

Locate the rods and snap links as shown above.

Rev: 2014.11.04.v002a

A quick link will be glued to the end o

the 4 control rods. Hold the rod with

your finger tips...

.... dunk it approx 1/2" into the nozzle

of the Welders tube as show and twist a

time or two.

Pull the rod out and check that you

have a nice even coat of glue as shown,

if not, repeat the process

Attach a snap link as shown. Notice

that the snap link has a "saddled" area,

this should be where you rest the

control rod

Repeat this for the other three control

rods and set a side in a safe place to

dry for a minimum of 24 hours

Locate all of the electronics you will be

using. Now is a good time to check that

everything is working properly

Rev: 2014.11.04.v002a

If using the Twisted Hobbys' power

combo, please read the included notice

regarding the electronics warranty

Create a program in your transmitter

for this model and bind the receiver as

required

Hook up the entire electronis system as

shown. Mount and center the control

horns and servos as shown. Test for

proper operation of all items

Now is also a good time to Calibrate

your ESC according to the included

directions

Locate the items shown above and

apply a tack coat to the mating surfaces

and let sit for approx 5 minutes before

joining together

While the glue in the previous step is

tacking up, locate the wood kit and

remove the 4 wing ribs as shown

Rev: 2014.11.04.v002a

Once the glue has tacked up, bring all

the pieces together. Note that all the

tabs and slots should line up and parts

are "keyed" for proper orientation

Clean out the slots in the wing where

the ribs will be installed. Note that the

ribs are the same width as the wing

thickness

Check the fit of the ribs to the slot in

the foam, with the exception of the

humped area, the rib should sit flush

with both the top and bottom surfaces

Test fit the wing spars and ribs on the

bench out side of the wing first, this

will give you an understanding of how

the pieces go together. No Glue

Close up of the left underside pieces.

No Glue

The bigger ribs are located toward the

fuselage and the small ribs towards the

wing tip. Note that we are working from

the bottom side of the aircraft
