CAR/TRUCK FAQ
  Why electric motors?
Electric motors are quieter, cleaner, and require fewer tools and accessories than gas powered motors.  Ultimately this results in fewer trips to and from the car. Electric enthusiasts find that they can navigate their toys in places gas powered motors can not including the back yard, indoors, or the park. Your neighbors may not like the sounds of Jet Planes, Dirt Bikes, or RC Cars.  Keep them happy , be quiet. Outrun your Nitro Friends.
  Why use MEGA Motors?
There are laws of physics that one cannot escape when choosing the proper motor for your radio control vehicle.  Furthermore, some argue that "what you cannot see in the motor" is one of the most important characteristics of a motor.  These characteristics include the number of windings, gage of the wire in the windings, and magnet material used.  MEGA Motors are made with neodymium, the best magnetic material on the market.  Additionally, they are  small in size and weight with dual ball bearing armatures are wrapped in Kevlar to prevent magnet ejection at high speeds.  MEGA Motor have a vented housing which improves thermodynamic characteristics allowing for a more robust operation.  The MEGA Motor design is like none other with a six pole three phase AC field with a permanent magnet rotor.  Additionally, the DC battery voltage is electronically commutated or switched to 3 phase delta AC and Pulse Width  is changed to control motor speed.  Most importantly, MEGA motors stand behind their motors by offering a two-year limited warranty. Traditionally RC Car motors have had "Fast" names and fancy flames on the case, but these marketing gimmicks do not make your car go faster, quality parts do.  Go Fast, Go Mega Brushless
  What is the difference between brushed and brushless motors?
If you get out your trusty old drill or circular saw and peak in the air vents at the rear and pull the trigger you will see sparks. That is the brushes at work. Magnetism is what makes electric motors work. When you have a north pole that is stationary (field) and a south pole that is mobile (armature), they attract and the south pole will move toward the north pole. Way back when electricity was discovered, someone decided to use brushes to commutate or switch the electricity to the armature. As the south pole approaches the north pole, the current flow is reversed (by the brushes) and it becomes a north pole too and is repulsed by the stationary field north pole causing it to keep on turning. The switch point is called timing. The sparks are wasted energy converted to radio interference or wide band noise. The speed or a brushed motor depends on how much attraction the magnetic poles have (how much current flows), the timing or switching , and the input voltage.
The electronic speed control (ESC) varies the voltage from your battery pack to your motor to control speed. In hobby motors, the field magnets are usually fixed magnets and the rotor or armature is an electro magnet (coil of wire with current flow).
Brushless motors operate on a different principal. They are AC (alternating current) 3 phase 6 pole motors. The speed is controlled by the number of poles and the frequency of the supply voltage. Brushless ESC (electronic speed controls) do this function. DC (direct Current from the battery is converted to AC and the frequency is changed by your thumb (and the Brushless ESC) to change prop speed.
  Why haven't brushless motors taken over the RC Car market?
There are two good reasons.  Electronic Speed Controls (ESC) are harder to make for RC cars & trucks because they have high start currents and require reverse.  Good ESC's are now available.  Many RC car enthusiasts like to race and rules often dictate the type of motor to be used.  This will change quickly as brushless motors are much better (Faster) and no one wants to race slow motors when fast motors are available.
