It is not necessary to change the needle settings if the engine

runs smoothly. Normally only the high-speed needle will need

adjustment from time to time and only by a small amount.

Factory carburetor settings are:

A. HSN 1-5/8 turns from the closed position (± 1/4 turn)

B. LSN 1 turn from the closed position (± 1/4 turn)

If you run into problems tuning your engine settings, it is best

to re-set the needles to the above settings and start over.

IDLE STOP ADJUSTMENT

The idle speed screw is used to adjust how fast the engine

runs at idle.

Once the high and low speed needles are properly adjusted

the idle speed can be set. To increase the idle speed turn the

screw in (clockwise), to slow the idle speed turn the screw out

(counter-clockwise).

RACING

Although it is very enjoyable to run the Rio 51Z by yourself or with

a buddy, the real fun and excitement of R/C boating is experienced

when you get involved in racing. Racing against other boats is much

different than running your boat alone. The following suggestions

will hopefully provide helpful strategies when racing a model boat.

A good set-up for running alone may not be the best for racing. Race

water conditions create challenges different from running alone

and water conditions constantly change during a race. Five or six

boats racing against one another will create rough water on the race

course. To compete successfully, it may be necessary to “tighten”

the ride characteristics. This can be accomplished by adjusting the

angle of the strut or trim plates.

Wakes caused by other boats can upset the balance and ride

characteristics of even a well trimmed model boat. When running

down the straight-aways, don’t follow in another boat’s wake. Wakes

generated by other boats while entering and negotiating a corner are

especially dangerous. Cutting across a wake when entering a corner

can cause the boat to “hook” (spin out).

Racing other boats through a corner may be a competitor’s greatest

challenge, especially the ﬁ rst corner after the start of a race. The

boat entering the corner ﬁ rst has the task of holding its position

(often called “holding your lane”) through the corner. The trailing

boats must then attempt to hold their lanes, too.

NATIONAL MODEL BOATING ORGANIZATIONS

There are two national model boating organizations in the United

States and Canada:

IMPBA or International Model Power Boat Association

www.impba.net

NAMBA or North American Model Boat Association

www.namba.com

Each of these organizations has its own rules governing model boat

racing, sanctioned events and recognized records. Organized model

boat racing is offered at both regional and national levels. Location of

clubs, race dates and locations, membership applications, and other

information can be obtained through their respective web sites.

A good source of information regarding all aspects of model boat

operation is:

International Waters

MAINTENANCE

When you are through operating your boat for the day, be sure to

perform these basic maintenance procedures. This will prolong

the life of the Rio 51Z and help to ensure trouble-free running.

• Wipe down the entire boat, inside and out, with spray-on

cleaner and a paper towel. If water is left in the boat, it could

get into the engine, potentially causing the piston ring to rust.

• Leave the cowl off the boat overnight to let

any water evaporate from the hull.
