Step 5: Install the Wing 

1.

 

Slide the two 1/8” x 2.5” dowels through the holes in one wing mount, through the 
fuselage, and through the hole in the other wing mount.  You will probably not need 

to glue the dowels in place. 

 

2.

 

Set the wing on the mount and secure it with 6 rubber bands. 

Step 6: Install the Motor 

You will need: 

 

Motor/gearbox (

not provided with kit

 

#2 x 3/8” motor retaining screw (

Bagged Parts

!

 

Installing the Motor 

1. 

Slide the motor over the motor mount stick and slide the motor as far back as possible. 

2. 

Using a small drill bit or the tip of an xacto, start a hole in the side of the gearbox for the 

motor retaining screw.  Screw in the motor retaining screw and then install the propeller. 

 

If you are using a GWS propeller, make sure the print on the blades is facing 

forward. 

 

Step 7: Install the Receiver and Speed Controller 

We are not going to cover the receiver and speed controller (ESC) specific information, 

please refer to your manufacturer’s instructions for more information, if necessary. 

Attaching the Receiver 

 

The receiver is positioned in the cutout in the fuselage below the wing. Connect the 
servos and ESC to the receiver, following the guides on the receiver itself.  The 

channel that you plug the ESC and servos into are dependent on the transmitter.  
For example, a Hitec transmitter uses channel one for the rudder (or aileron if you 

have the SP wing), channel two is elevator, and channel three is the throttle.  Other 

brand transmitters may assign channels differently. 

 

Once the receiver is installed, you can close the fuselage opening with some wing 
tape.
