• For 

“drag racing”

place the buoys similar to the above sketch.

•For 

“oval  racing”

place  the  buoys  similar  to  the  above

sketch. 

NOTE:

The above patterns are not based on any sort

of  official  standards;  therefore,  you  may  set  up  racecourses
any way you desire, using your imagination to make the races
more  interesting.  Usually  the  smaller  courses  will  provide
more action and excitement.

The length of the races can be determined by a set number of

laps

around the buoys (for example, the first boat to complete

5  laps  is  the  winner);  or  by 

time

(for  example,  whoever  is

leading at the end of two minutes is the winner).

The Waiting Game

If your Nitro Hammer should happen to stall or capsize, water
currents will 

slowly

carry it to shore. The bad news is that the boat

could be carried to the opposite shore. When surveying areas to
run your Nitro Hammer, keep in mind things like wind direction,
size of the lake, strength of river currents, etc. 

HELPFUL TIP:

Use

a fishing rod with at least 12lb. line and a tennis ball tied to the
end to retrieve a stalled or capsized model boat.

GOOD LUCK AND GREAT BOATING!
