Do  not  use  too  much  force  when  tightening  self-tapping
screws  into  plastic  or  fiberglass.  Over  tightening  will  cause
the  threads  in  the  plastic  to  strip. We  recommend  that  you
stop  turning  a  self-tapping  screw  once  you  feel  some
resistance as the head of the screw comes in contact with the
plastic. Avoid using powered screwdrivers when assembling
this  kit.  They  tend  to  over  tighten  the  screws.  Do  not  use
thread-locking compound on self-tapping screws. The thread-
locking  compound  may  damage  the  plastic. 

IMPORTANT:

Use thread lock on any fastener that is threaded into metal or
fastened with a nut. Vibration from the engine will cause the
screws to loosen if thread-locking compound is not used.

Transmitter Assembly

❏ 

1. Remove the transmitter

antenna  from  the  parts  bag
and  screw  it  into  the  top  of
the  transmitter.  To  ensure
that the antenna is attached,
lightly  pull  on  the  base  of
the antenna. If it slides out, it
is not installed properly.

❏ 

2.  Slide  off  the  battery

door  on  the  bottom  of  the
transmitter. Install 8 new “AA”
batteries  into  the  bottom  of
the 

transmitter 

in 

the

configuration molded into the
battery  holder.  Re-install  the
battery door onto the bottom
of the transmitter.

❏ 

3. Turn the transmitter on using the switch on the front. The

red LED light next to the on/off switch should light up. If the
LED  does  not  light  up,  turn  the  transmitter  off  and  check  to
make sure that the batteries are installed properly. 

If you see a

flashing LED, the batteries are low and need to be replaced.
