1)

  Plug the servo leads and the switch lead into 

the receiver. You may want to plug an aileron extension 

into the receiver to make plugging in the aileron servo 

lead easier when you are installing the wing. Plug the 

battery pack lead into the switch.

 

2)

   Wrap the receiver and battery pack in the protec-

tive foam to protect them from vibration. Use a rubber 

band or masking tape to hold the foam in place.

3) 

 Position the battery pack and receiver behind 

the fuel tank. Use  two tie wraps to hold the battery and 

receiver securely in place as pictures below.

Do  not  permanently  secure  the  receiver  and  battery 

until after balancing the model. 

 

4)

  Using a 2mm drill bit, drill a hole through the side 

of the fuselage, near the receiver, for the antenna to exit.
