2. Remove the body clip that holds the lid to the radio box

and carefully remove the cover.

❏ 

3.  Carefully  uncoil  the  receiver  antenna  and  route  it

through the small hole on the side of the radio box and up
through the antenna hole.

❏ 

4.  Slide  the  antenna  wire  through  the  antenna  tube  and

place  the  antenna  tube  into  the  rubber  grommet. 

DO  NOT

CUT OFF THE EXCESS ANTENNA WIRE!

Installation of Batteries

❏ 

1.  Place  four  (4)  new  “AA”  batteries  into  the  receiver

battery  holder.  Be  sure  to  follow  the  configuration  molded
into the battery holder.

❏ 

2. Put the radio box cover back on and replace the body clip.

Check the Radio System:

❏ 

1.  Standing  behind  the  boat  with  both  the  vessel  and

transmitter powered up, rotate the wheel to the left. The back
of the rudder should move towards the left. Move the wheel
to the right. The back of the rudder should move towards the
right.  If  this  is  not  the  case,  simply  move  the  steering  servo
reverse switch to the other position.

❏ 

2. Squeeze the trigger on the transmitter; this should open

the  throat  of  the  carburetor.  Conversely,  moving  the  trigger
forward will close the throat completely.

❏ 

3. The adjustable steering rate knob (labeled D/R) located atop

the  transmitter  (see  page  3)  is  the  steering  rate  adjustment.
Turning the knob to the right increases the amount of travel of the
rudder while turning it to the left decreases the rudder amount of
travel. Beginners may want less amount of travel to start with.

Before  running  the  engine,  read  the  manual  and  watch  the
video that came with this kit.

There are Several Simple Steps to Starting the Engine:

❏ 

1. Install a glow plug if one is not in your engine. The glow

plug threads into the top of the cylinder head.

❏ 

2. Fill the tank almost to the top. Leave a little air at the top

of the tank.
