 4. Install the tail cone. Use cellophane tape (household 

tape) to secure it to the hatch and the fuselage. If you choose 
to use glue, R/C-56 Glue (JOZR5007) will allow easy removal 
of the hatch in the future. Medium CA is also acceptable, but 
only if two small drops are used 180° apart from each other.

GET THE MODEL READY TO FLY

 1. Stick the hook side of the 4" [102mm] piece of hook and 

loop material to the battery tray in the location shown.

 2. Locate the parts to assemble the foam display stand. There 

should be two side braces, two top braces (small), two bottom 
braces (large), and two interlocking supports. Note: The foam 

display stand is not made of AeroCell

 foam. Only foam-safe 

CA adhesive can be used. Regular CA will melt the foam.

 3. Assemble the stand by fi rst interlocking the supports 

and then adding the two vertical side braces. Add the top 
and bottom lateral braces next. The top braces are smaller 
to allow the aileron servos and linkages to clear.

 4. Apply the pre-cut decals, using the box photos as a 

guide for placement

Check the Control Directions

 1. Turn on the transmitter and receiver and center the 

trims. If necessary, remove the servo arms from the servos 
and reposition them so they are centered. Reinstall the 
screws that hold on the servo arms.

 2. With the transmitter and receiver still on, check all the 

control surfaces to see if they are centered. If necessary, 
adjust the screw-lock pushrod connectors to center the 
control surfaces.

 3. Make certain that the control surfaces and the ESC 

respond in the correct direction as shown in the diagram. 
If any of the controls respond in the wrong direction, use 
the servo reversing in the transmitter to reverse the servos 
connected to those controls. Be certain the control surfaces 
have remained centered. Adjust if necessary.
