❏ 

7. Put a bead of CA glue on the rubber throttle pushrod

seal and insert it in the radio box as shown.

❏ 

8. Place the radio box into the radio box seat on the Top

Speed 2 hull as shown and decide where you want to place
the ON/OFF switch. Note: The Top Speed 2 radio box is taller
(slanted) at the aft end to provide more clearance for the
control horns. Place the switch plate of your ON/OFF switch
on the radio box and outline it with a marker. You will need to
cut a notch in the cowl 
to accommodate the switch, so the
closer you place the switch to the deck, the easier it will be to
take the cowl on and off. We have provided a water-resistant
switch cover that you may use with your switch. The size and
shape of your ON/OFF switch may vary from the one shown.
Refer to your radio system manual for proper radio set-up. DO
NOT permanently attach the radio box to the hull as you
will need to remove it from time to time.

❏ 

1. Cut two X-shaped servo arms down to the

configuration shown above. Note that the lengths of the
remaining arms have also been decreased by one hole.

❏ 

2. Install two servos with rubber grommets and eyelets as

shown. Note: Be sure to install the servos exactly as shown,
paying close attention to the location of the output shafts.

❏ 

3. Install the two servos arms from Step 1 as shown.The port

(left) side servo is the steering servo (with full arm) and the
starboard (right) side servo (with 1/2 arm) is the throttle servo.

TIP: It is a good idea to install a high-torque servo for
steering (Futaba S3305). Refer to the manual that came
with your radio system for servo information.

A third slot has been provided to accommodate a mini-servo
should you decide to install an onboard mixture
control (OSMG8336).
