MOTORS AND GEARING
MORE TIPS
THERE ARE TWO DIFFERENT TYPES OF AFTERMARKET MOTORS WHICH CAN PURCHASED FOR YOUR MODEL,STOCK AND MODIFIED.STOCK MOTORS ALL HAVE THE SAME WIRE THICKNESS AND NUMBERS OF TURNS ARMATURE AS GOVERNED BY SANCTIONED RACING ORGANIZATIONS.THEY ARE INEXPENSIVE,AND WIDELY AVAILABLE.MODIFIED MOTORS ARE MORE EXPENSIVE,MAY FEATURE BALL BEARINGS AND COME IN A VARIETY OF WIRE THICKNESS AND NUMBERS OF TURNS OF WIRE ON THE AMATURE. THE FEWER NUMBERS OF WIRE ON THE AMATURE ,THE MORE POWERFUL THE MOTOR WILL BE. KEEP IN MIND THAT THE MORE POWERFUL THE MOTOR,THE LESS BATTERY RUN TIME YOU WILL HAVE. ONE OF THE MORE SIGNIFANCT ADVANTAGES TO YOUR MODELS TRANMISSION IS THE EXTREMELY WIDE RANGE OF AVAILABLE GEAR RATIO'S. IT CAN BE GEARED LOWED ENOUGH  TO RUN EXTREMELY HOT,MODIFIED MOTOR.MODIFIED MOTORS SHOULD BE GEARED LOWER (HIGHER NUMERICALLY)THAN STOCK MOTORS BECAUSE THEY REACH THER MAXIMUM POWER AT HIGHER RPM'S.A MODIFIED THAT IS GEARED INCORRECTLY CAN ACCTUALLY BE SLOWER THAN A CORRECTLY-GEARED,STOCK MOTOR USE.USE THE FOLLOWING FORMALA TO CALCULATE THE OVERALL RATIO:IF YOU ARE WORRIED THAT YOU MIGHT BE UNDER OR OVERGEARED,CHECK THE TEMPERATURE OF THE BATTERY PACK AND MOTOR.IF THE BATTERIES ARE EXTREMLY HOT,AND/OR THE MOTOR IS TOO HOT TO TOUCH,YOUR MODEL IS PROBABLY OVERGEARED.IF YOU ARE NOT ABLE TO RUN YOUR MODEL FOR AT LEAST FOUR MINUTES BEFORE THE BATTERY DIE,THEN CHANGE TO A LOWER GEAR RATIO.THIS TEMPERATURE TEST ASSUMES THAT THE MODEL IS CLOSE TO FACTORY STOCK WEIGHT AND OPERATES FREELY WITH NO EXCESSIVE FRICTION,DRAGGINGM,OR BINDIN.THE MODEL IS EPUIPPED WITH A MILD 20-TURN MODIFIED MOTOR.THE GEAR COMBINATIONS THAT COME STOCK ON EACH MODEL WILL PROVIDE GOOD OVERALL ACCELERATION AND TOP SPEED.IF YOU WANT MORE ACCELERATION AND LESS TOP SPEED,USE SMALLER PINION GEAR (FEWER TEETH).FOR MORE TOP SPEED USE A LARGER PINION GEAR.
WHEELS AND TIRES
Many types of aftermarket tires and wheels can be adapted for most
models. Most will affect the overall width and the suspension
geometry of the model. The offsets and dimensions designed into the
model's wheels are intentional; therefore, we cannot recommend
the use of other wheels with different specifications. The diameter of the
wheels on the model are industry-standard sizes, so there are an
abundance of different tires available for you to experiment with.
Experimentation with different types of tires is recommended to see
which ones work the best on the terrain where the model is run.
When selecting tires, consider the overall diameter and the rubber compound
(hard or soft). If the overall diameter of the tire is significantly increased,
you will need to use a smaller pinion gear (clutch bell) to compensate for
the larger tire. Soft compound tires with many short spikes generally
work better on hard, dry surfaces. In loose dirt, a harder tire with large
spikes should perform better.
CLEANING
I have found some general purpose cleaning tips and thought they
should be shared. First off, DONT use paint thinner on any plastics.
I completely stay away from it for cleaning. Its some bad stuff on the
right parts. Secondly, get some Denatured Alcohol (rubbing alcohol
will not cut it, it has too much water in it for cleaning). This stuff is cheap.
You should be able to find it at Home Depot or Lowes. I use it on everything.
Hot water and dish soap work very well on oily greasy parts. Anyways,
you might also want to invest in a crappy tooth brush or maybe
a finger nail brush. These will work good for most of your scrubbing.
Now before diving into that muddy mess you just brought in, you
should clean as much of the big dirt as possible. I look at it like this,
why add more dirt to your cleanner parts? You might want to use an
air compressor. If you dont have access to one, you can buy compressed
air for computer cleaning. This works ok, but a compressor is much
better. Now that the big dirt is off, start tearing things down, one by one
(so you dont mix up parts), and clean them. Now would be a good
time to check for wear and/or damaged parts. Make sure once you have
it cleanned the way you want it to dry it out. Use Q-tips (another
useful cleaning tool by the way) to dry out the hard to reach and small
areas. Make sure once cleanning is complete that you reassemble
everything like the instructions say. Also, if you want to try using other
chemicals for cleaning, please test it on an inconspicuous area first.
You should take my word and learn from my mistakes on this one.
