General rules
1.
This is a fun event. Any person taking it too seriously will be
ridiculed and shunned.
2. Teams are welcome to wear racing suits, fireproof overalls,
helmets, goggles etc., but do so at the risk of being laughed at.
3. Sponsorship
logos, racing stickers and car names are encouraged but no
obscenities please.
4. Wings for
down force, spoilers, air dams and other appendages are all
permitted so long as they fit within the maximum dimensions of the
racer. They probably won’t do any good but we can all have a
good giggle at them.
5. The judges’ decision is final although bribes are greatly
received!
Modified Class Racer
This
class is for the all out honor of having the fastest international
Mini rocker cover, that isn’t attached to a Mini engine.
Creativity for speed and design is welcomed, but rules are rules.
The following rules are the requirements that are checked at
pre-race inspection. Other than these rules, it’s open to your
creativity and abilities.
1.
All ages. Kids to great great grandparents.
2. Body: Begin with a stock or aftermarket A series Mini rocker
cover. Modifying and decorating is open and encouraged as long as
it is still recognizable as a Mini rocker cover.
3. Wheels: 4
wheels are required and all 4 must be in contact with the track
during the race unless the racer catches air due to the track
conditions. Wheel design and material is open. Maximum wheel
diameter is 5 inches.
4. Wheel
bearings: Open. Lubricants are open.
5. Axles: Open.
6. Gravity is
the only power source. There can not be anything mechanical that
would affect the speed.
7. Maximum dimensions and weight:
Length – 14 inches (35.56 cm)
Width – 8 inches (20.32 cm)
Height – 8 inches (20.32 cm)
Weight – 8 pounds (3.628 kg)
Kid's Class Racer
This
class is designed for kids to learn how to build a racer, be
creative, and have fun racing other kids. The rules were created
to keep all of the racers closely competitive while allowing the
kids to be the builders with minimal adult help. The following
rules are the requirements that are checked at pre-race
inspection. If the racer looks to have too much adult involvement
or does not meet the following rules, it is up to the judges to
move the racer to the Modified Class for consideration. Note,
the rules are as basic as putting a rocker cover on top of a very
small skateboard. The extent of the rules is to keep it that basic
and equal.
1.
Age: 12 and under at the time of the race.
2. Tools: No
tools beyond standard hand tools, saws, and drills can be used. No
welding or machining.
3. Body: Begin
with a stock type steel A series Mini rocker cover. Modifying and
decorating is open and encouraged as long as it is still
recognizable as a Mini rocker cover.
4. Wheels: 4
stock skateboard or roller skate wheels made of urethane or
rubber. Maximum diameter 2 ½” (65 mm). Minimum width 1.18”
(30 mm). The wheels can not be modified or worn to reduce the
width touching the track surface. All 4 wheels must touch the
track during the race unless the racer catches air due to the
track conditions.
5. Wheel
bearings: Steel ball bearings only. If the bearings are in
question, be prepared to remove the dust covers to show them for
inspection. Lubricants are open.
6. Axles: Stock
skateboard or roller skate trucks. The only modification allowed
would be to do what is needed to lock the truck from moving, if so
desired.
7. Gravity is
the only power source. There can not be anything mechanical that
would affect the speed.
8. Maximum dimensions and weight:
Length – 14 inches (35.56 cm)
Width – 8 inches (20.32 cm)
Height – 8 inches (20.32 cm)
Weight – 7 pounds (3.175 kg)
The Race
1. There will be heats of 2 Racers per heat with the best of 3
races deciding the heat winner.
2. The first Racer to cross the finish line is the winner. If
neither Racer makes it to the finish, the one going the furthest
distance wins that race.
3. Any Racer crossing a lane marker shall lose that race
4. Winning Racers will advance to the next round until all are
eliminated except one, which becomes the outright winner.
5. Any protest must be lodged with the judges who will remind you
of General Rule #1.
Building a Kid's Racer
(Can also be used to build a Modified Racer)

Step 1. After printing and cutting out the template,
choose the material you want to use as the base. This example
shows 1" x 4" pine (actual size .75" x 3.5".
Silly they sell it as a 1" x 4"). Using a thick board
allows you to countersink the rocker cover mounting bolts as they
will be mounted under the skateboard trucks. Trace the template
outline on to the base. Cut the piece of wood or whatever you want
to use as your base.

Step 2. Get either new or used skateboard trucks
and wheels. The Kid's rules also allow roller skate trucks and
wheels. Pictured is a used skateboard that was purchased from
Facebook Marketplace for $5. We bought another one for $3, so your
racer can be done very cheap. Note the trucks come in different
widths. They are all legal in the Kid's and Modified Classes, but
they will make a difference on how they mount in/under your rocker
cover. With these 7.5" trucks, the wheels will clear the
cover body without any modifications.

Step 3. Tape the template on the wooden base.
Now it's time to figure out the wheel base that you want. Place
the trucks along the center of the template. Set the rocker cover
on top of the trucks, lining the front and rear of the cover over
the base. Slide the trucks on the template to a position you like.
Remove the cover, leaving the trucks.

Step 4. Before marking the holes, use a
straight edge (a piece of paper can be used) to line up the
trucks. Mark the outer two holes on each truck.

Step 5. Use an awl or any pointed object to
punch the center of the truck holes and the rocker cover mounting
bolt holes.

Step 6. Drill the holes. Note, the bolts
for the rocker cover mount are 5/16" x 24".
For this example, we used 1 1/4" long bolts. Countersink the
cover mount holes on the truck mounting side with either a bigger
drill bit or use a wood chisel. It doesn't have to be pretty as
the trucks will cover them.

Step 7. Mount the trucks with the two outer
bolts on each. Tighten firmly, but loose enough that you can still
slightly move them for alignment. Use your straight edge again and
line up the trucks. Tighten the bolts and check the alignment
again. Once tight and aligned, drill the other truck holes. Put in
the final truck bolts and tighten. Remember that any time you
remove the trucks that you will need to re-align them before
tightening completely.

Here it is, your Kid's racer base made
with minimal tools and money!

Step 8. The base will fit inside your cover with
the mounting bolts going up through the cover holes. You can
adjust your cover height with spacers/washers on the cover bolts
or be creative.

Now it's ready to paint, decorate, and decide if
you want to change the wheels and/or bearings. The rules above
have the wheel and bearing requirements.
Add weight if you would like. There is plenty of room to mount it
under the base, between the trucks. The total weight for the Kid's
class is 7 lbs., and 8 lbs. for the Modified class. Is heavier
faster?

Ready to race, minus the kid's personal touches.
This was painted with Rust-Oleum primer and paint from aerosol
cans (cheap). The wheels (30 mm) and steel bearings were bought
off of Ebay for about $25.
