result in a serious burn. 
* Gasoline is poisonous. Do not allow it to come into contact with the eyes or mouth. 
Always store fuel in a clearly marked container and out of the reach of children. 
* Gasoline  is extremely  volatile.  Never  allow  naked flame or any possible source of 
ignition near your boat. Be very careful when re­fuelling your boat. 
* This boat is set up to racing standards. If you are starting from scratch at driving a 
fast boat, get a more experienced driver to take your boat out  for the first few times. 
When you are initially going faster, do so on clear waters away from other boats and 
with  your  more experienced driver  close  by to give advice and support. If  you don't 
know  an  experienced  driver,  find  an  RC  Boat  Club  in  your  area  and  join  up.  Most 
clubs  welcome  new  members  and  nearly  always  have  experienced  drivers  who  will 
help you. It's more fun running your boats with others too. 

Step 1: Accessories Check 

In order to avoid your boat being damaged during transportation, we 

removed the flexible shaft, turn fins, rudder, propeller and some other 

items of the hardware. When you receive the boat, please first check the 

accessory bag for these items as shown in the photo below. You will need 

to install them (as we'll explain in the following steps) before you are able 

to operate your boat. 

Your accessory bag should contain the following items:
