Gently pull the rubber drain plug located on the transom and
allow any water that may have found a way inside the hull to
drain out. Be sure to replace the plug before running the
boat again.

MOTOR MOUNT SCREWS

Moisture inside the hull can cause the 6-32 cap head screws
that hold the motor mount to the transom to corrode. Remove
the screws one at a time, eliminate any moisture/corrosion by
applying a coat of lubricating spray (WD 40) and replace the
screw. This procedure should be done when finished running
for the day. Failure to do so can result in difficulty removing the
screws from the brass inserts in the transom. Attempting to
remove a corroded screw can result in removing the brass
insert from the transom.

ENGINE MAINTENANCE

When you are through running your Top Speed 2 for the day,
be sure to remove all fuel from the tank and follow the
procedure below:

❏ 

1. Remove the glow plug.

❏ 

2. Open the carburetor.

❏ 

3. Spray WD-40 into the open carburetor.

❏ 

4. Apply the starter to the starting cone and flush the

lubricating spray out of the engine.

❏ 

5. Place a few drops of Hobbico After Run Oil (HCAP3000)

into the carburetor and in the cylinder head.

❏ 

6. Apply the starter and flush the after run out of the

engine. A sufficient amount will remain to coat the
engine components.

❏ 

7. Prior to starting the engine, with the glow plug

removed, open the carburetor, and pull fuel through the
engine (choke) by placing a finger over the carburetor by
spinning the flywheel. This will clear the after run oil.

❏ 

8. Remove the flex cable and inspect for broken strands

of wire or kinks. Grease the cable and reinstall in lower unit.
Note: You will need to refer to your engine’s manual for
information regarding this procedure.

Although it is very enjoyable to go out and run the Top
Speed 2 by yourself, 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 tunnel boat.

A good set-up for running alone may not be the best for
racing conditions. 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 conditions on the race
course and to successfully compete in racing situations, it
may be necessary to “tighten” the ride characteristics. This
can be accomplished by lowering the depth of the propeller
or adding additional weight to the front of the boat.

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” (pin to the inside) and stall.

Racing other boats through a corner presents possibly the
greatest challenge and the first corner after the start of a race
can be especially challenging. The boat entering the corner
first has the task of holding its position (often called “holding
your lane”) through the corner and following boats must then
attempt to hold their lanes. Changing lanes and crossing a
wake to gain a position in a turn can result in “hooking” the
boat and elimination from that race. Executing a good start in
the inside lane is one key to successful racing.

Avoid beating yourself. In any type of racing, there are some
situations you can control and other situations that you
cannot control. The ability to set the needle-valve on the
engine so it runs the entire race without stopping, checking
the linkages, fasteners, fuel tubing, amount of fuel, glow
plug, and radio system are conditions/situations that can be
dealt with prior to the start of a race. During the race,
making a good start and driving defensively are controllable
actions. By focusing on tasks and actions that can be
controlled, successful racing outcomes can be achieved.

There are three national model boating organizations in the
United States and Canada:

APBA or American Power Boat Association

(RC Boat Category) 

www.apba-rcboating.com

IMPBA or International Model Power Boat Association

www.impba.net

NAMBA or North American Model Boat Association

www.namba.com

Each of the three organizations has its own rule book
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 websites.
