Transmitter Set Up

Please note that we do not include radio systems in our RC boat
packages as most modelers already have their own preferred RC
system. This approach also saves the extra cost that the radio
would incur. However, we do include both throttle servo and
steering control servos in Hi-Torque Metal Gear version with
all of packages, This servos are in standard size, yet they have
all the power you need for precise control of the steering and
throttle system at high speeds.

All you need is to provide your own preferred transmitter and
receiver, we do recommend customer to equip a well quality of
three or four channel of 2.4GHz RC system with built-in
function of fail safe to avoid the boat out of control during lost
signal.

Trimming Your Throttle Function

The Arrow Shark X-30 or X-60 Marine engine come with integrative metal gear servo installed for the
throttle control, just simply connect the servo extension wire to your receiver in throttle slot.
Adjust the push-rod so that the carburetor is fully open at full throttle and at a reliable idle when the
throttle is at neutral. You can adjust your throttle linkage with the push-rod ball joint connector. You may
need to adjust this linkage when you first start your engine.
Note: It may take some trial and error with both the pushrod and your radio trim and "EPA" (End Point
Adjustment) functions, but you need to end up with the throttle linkage set so that:
1.The engine idles reliably, but not too fast, when the transmitter trigger is at its neutral position.
2.When you pull the trigger fully open for high speed, the servo movement should fully open the
carburetor barrel hole.
3.When you push the trigger fully closed, the engine must stop.
