Welcome to my
R/C tuning page. To the left you will find some of the most common topics
in electric R/C. Below you will find some of the most frequently asked
questions.
How Fast Does an R/C Car go?
This is a very common question for people new to the RC. To simply answer the
question, anywhere from 20 to 100+ MPH. On your typical track the top
speed is usually not more than 40MPH and you would be more concerned about
'corner speed' and your total lap time.
Which is Faster Nitro or
Electric?
An age old question. The truth of the matter is they have the same potential as
far as top speed is concerned. It all boils down to what motor you put in it and
how you gear it.
What is a frequency?
A
frequency is a signal that is transmitted from your RC Radio to your receiver in
your car. When you bought your radio, it included a frequency, or channel,
which came in the form of a set of crystals. Each set of crystals is assigned a
number (see list below). If turn on your radio on and someone else is on
the same frequency (channel), they're car is going to go out of control and
possibly get damaged. So, be VERY careful when you turn on your radio. At most
tracks, there is a frequency clip board. If not make sure you ask the driver's
on the stand channel they are on. Above all never turn your radio on
during a race, unless you are on the stand.

To operate any RC LAND vehicle with a frequency outside the
following spectrum is illegal. (RC Airplanes use a separate spectrum and do not
interfere with RC Land vehicles.)
There are two
different frequencies AM and FM what is the advantage of FM over AM?
FM has a stronger signal than a AM. The
difference in clarity and interference resistance is the most noticeable
difference. AM is fine if all you're going to do is play around in your back
yard with your RC. If you're going to go race with a bunch of friends or at a
track, then FM is the only way to go. There is nothing worse than trying to
drive a car that is glitching or sudden decides to turn right instead of left.
What is the
difference between 12 gauge wire and 14 gauge wire?
12 gauge wire is thicker and it will conduct a lot more efficiently than 14
gauge wire. The 12 gauge wire is said to have less resistance than a 14
gauge wire that is the same length. All in all the 12 gauge wire won't
heat up as much. The less heat in RC anything, the better.
What is a gear ratio?
A Gear ratio is represented by X:Y where x is the # of
rotation of the wheel and Y is the # of rotation of the motor or engine.
Example a gear ratio of 1:10 would mean in order to rotate the wheel once on
the ground, the motor or engine must rotate 10 times. Decreasing the
number of teeth on your pinion gear you will increase the overall acceleration
and decrease the top speed of your vehicle. Increasing the number of teeth
on your pinion gear, you get the opposite effect.
