I.    SAFETY PRECAUTIONS & ASSEMBLY TIPS: 
            (

IMPORTANT – READ THIS SECTION BEFORE YOU BEGIN ASSEMBLY

1.

 

This product should not be considered a toy, but rather a sophisticated, working model that functions much like a full-scale 
airplane. Because of its performance capabilities, this product, if not assembled and operated correctly, could cause injury 
to you or spectators and damage to property. Maxford USA provides you with a high-quality, thoroughly tested model 
airplane kit with assembly instructions. However, the quality and capabilities of your finished model airplane depend on 
how you assemble it, and your safety depends on how you use and fly it. Any testing or flying of this model airplane is 
done entirely at your own risk. 

2.

 

Assemble this model airplane according to these instructions. Do not alter or modify the model beyond the assembly and 
power system options covered in these instructions, as doing so may result in an unsafe or unworkable model. In a few 
cases the instructions may differ slightly from the photos; in those instances the written instructions should be considered 
as correct. If you have a question or concern about these instructions, before you proceed with assembly of this product, 
contact your dealer or speak to a Maxford USA customer service representative at 562-529-3988 (Monday through Friday, 
except national holidays, 9 AM to 5 PM Pacific time). 

3.

 

While this kit has been flight-tested to meet or exceed our rigid performance and reliability standards in normal use, if you 
elect to perform any extremely high-stress flying, such as racing or advanced aerobatics, or if you install a larger power 
system than specified, you (the buyer or user of this product) are solely responsible for taking any and all necessary steps 
to reinforce the high-stress points and/or substitute hardware that is more suitable for such increased stresses. 

4.

 

Throughout the lifetime of this model, use only the Maxford USA-recommended or same-sized engine or motor and a new 
or well-maintained radio control system and batteries recommended by the maker of your motor and radio system. 

5.

 

It is your responsibility to install the R/C system and other components in such a way that this model airplane passes all 
applicable safety/range tests and that the power system and controls operate correctly and smoothly. 

6.

 

Recheck the operation of this model airplane before every flight to ensure that all equipment is still operating correctly and 
that the model has remained structurally sound. Also before every flight, check all electrical and structural connections; do 
not fly without properly connecting or replacing any that you find poorly connected, damaged or worn. 

7.

 

Before you begin assembly of this model airplane, read all instructions and test-fit each part to ensure you fully understand the 
instructions and that no parts are missing, damaged or unsatisfactory. Temperature and/or humidity differences between the 
factory, our warehouse and your home or workshop may dictate the need for slight adjustments to the wings, struts and/or the 
vertical or horizontal stabilizer‟s mounting surfaces to ensure proper alignment; however, we recommend you contact us before 
you attempt any such adjustment(s). 

8.

 

To help ensure the security of any in-line servo-type connections, optional Maxford USA servo-extension 
safety clips are recommended. 

9.

 

Assemble EZ Link connectors (whether included or an option for 
this model). As shown at the right, when   
applying threadlock compount or CA adhesive, 
be careful to 

NOT

 glue the EZ Link connector to the   

control arm or mounting tab; also be careful to not   
let the pushrod rub or bind against nearby surfaces. 

10.

 

As shown at the right, this model allows customers some choice in aileron servo selection: 

a.

 

Test-fit your aileron servos and the supplied wood mounting pedestals to the servo 
hatch covers.

 

b.

 

Use epoxy to attach the mounting pedestals to each servo hatch cover. Use the   
hardware provided with your servos to mount the aileron servos to their hatch covers.

 

c.

 

Using your radio or a servo tester, center the aileron servos. (You may be interested to 
learn more about servo testers at 

http://www.maxfordusa.com/servo.aspx

.)

 

d.

 

String may be supplied to pull your servo‟s lead and servo extension 
through the wing to your radio receiver; however, you may find it 
easier to use masking tape to temporarily attach the connector to the 
end of a length of coat-hanger wire, then use the wire to pull the lead 
and connector through the airframe as shown at the right.     

 

e.

 

Guide the servo into the servo bay, cover the servo bay with the   
servo-hatch and secure the hatch with screws or glue.

 

11.

 

After you have determined each servo-mounting-screw‟s location, apply thin CA adhesive to harden the wood where the 
servo‟s mounting screws will be inserted.
