of choosing a motor and ESC/MSC and Brushed vs.
are always a ton of threads about motors and ESCs
and they are all usually variants on the same
questions. In this article I will go through and
explain the basics of choosing a motor and ESC/MSC,
and talk about brushed vs. brushless systems.
choosing a motor it is important to choose one
that meets your abilities and budget. The first
thing to consider when buying a motor is how fast
you realistically want the car to go. I know you
all want your cars going 50mph, but there are
only a few of us who have enough driving experience
to go that fast without hitting straight into
a wall. The basics on turns and winds are as follows:
Turn = Higher Top End/Less Torque
Higher Turn = Lower Top End/More Torque
you look at motors with lower winds, you begin
to see motors like a 9x3. This means that the
motor is 9 turns and has 3 winds. The winds are
simply for more speed, the more you have, the
faster you go. One thing to note about lower turn
motors is that they need a lot more maintenance.
You can probably run a stock motor (27T) for 15-20
runs before it needs to have the commutator cut.
On the other hand, a 9T motor needs to be cut
every 3-5 runs.
are a few classes for brushed motors:
Stock (27 Turn)
19T Spec (19 Turn)
Unlimited (Any amount of turns)
hobby shop or race track may have others, but
these are the common ones.
whether to get an ESC or MSC is an easy decision.
Get an ESC. MSCs (Mechanical Speed Controls) are
very outdated and cannot handle today's motors.
When choosing an ESC you truly have to rate your
skill level. While you may have a 19 Turn motor
today, will you be changing to an 8 Turn motor
soon? The answer is probably not. An ESC's limit
is the lowest number of turns that it can handle.
Now you have to make a big decision. Since ESCs
that can handle lower turn motors are more expensive,
you will have to decide how low you're gonna go.
It makes no sense to buy an ESC with no turn limits
if you are going to race Stock and 19 Spec, nor
does it make sense to buy an ESC with a 17T limit
if you are going to race Unlimited. This is basically
up to you (and your budget), but be reasonable
and get an ESC with a limit that is around your
final rant will be on brushed vs. brushless. While
these systems are in relatively the same price
range, they each have their own pros and cons.
A brushed system needs a lot of maintenance, but
offers more flexibility because you can change
motors depending on track conditions (how much
torque you need). A brushless system on the other
hand, needs almost no maintenance.
are two basic decisions you need to make when
buying a brushless system. How much can you afford
to spend and how many transmission gears you want
to replace. The Novak systems are more affordable,
ranging from about $180-210 and include both a
motor and ESC. The next level up would be a Warrior/Feigao
combo which will be about $250 and will have more
power and a nicer ESC. The highest level of brushless
are the Hackers, Lehners, and Shulze. These are
not for novices, and must be geared almost perfectly.
These systems can range from about $400-800 for
just a motor and ESC. Also note that the Novak
and Warrior/Feigao combos offer better customer
support and are easier to get.
hope this article has answered most of your questions
about motors and ESCs. Good luck, and have fun!
