Before Starting Assembly

Before beginning the assembly of your model, remove 

each part from its bag for inspection. Closely inspect the 

fuselage, wing panels, rudder and stabilizer for damage. If 

you find any damaged or missing parts, contact the place 

of purchase.
If you find any wrinkles in the covering, use a heat gun 

(HAN100) and covering glove (HAN150) or covering iron 

(HAN101) with a sealing iron sock (HAN141) to remove 

them. Use caution while working around areas where the 

colors overlap to prevent separating the colors.

Binding the Radio System

Before starting the assembly of your model, we recommend 

preparing your radio system for installation. This includes 

charging the transmitter and receiver batteries, as well as 

centering the trims and sticks on your transmitter. If using 

a computer radio, make sure to reset a model memory 

and name it for this particular model. We also recommend 

binding the transmitter and receiver at this time following the 

instructions provided with your radio system.

Note

: We highly recommend re-binding the radio 

system once all the control throws are set. This will 

keep the servos from moving to their endpoints 

until the transmitter and receiver connect.

Note

: Before beginning this section of the 

manual, set the throws for the flap servo at the 

transmitter to 0% in both the up and down positions. 

This will center the flap servo, allowing you to 

properly install the servo arm and linkage.

 

1. Locate the items necessary to install the aileron and 

flap servos and linkages. You will also need the left and right 

wing panels for this section of the manual.



 2

. Check the hinges in each wing panel to make sure 

there is no excess adhesive that might prevent them from 

moving. Use a hobby knife and a #11 blade to remove any 

excess adhesive if any is found.
