Brushless Motor

What is the best brushless motor and ESC for a 1/10th scale rc buggy?
I currently have a 1/10th scale Team Associated RC10B4, and im looking to upgrade my motor. I was looking at the castle creations MAMBA MAX 7700kv motor. Are there any other motors and ESC's that will perform better than the mamba?
mamba will do the job.
a bit pricey though.

Brushed vs Brushless -- Motor Control elab Chapter 2
How You Can Use Motor Controls?
Motor controls are a device that controls the position, velocity, and torque of a mechanical drive. It is designed for motion controls of electrical motors. It has automatic and manual transmissions for starting and stopping the motor, and choosing and regulating the speed.
It is also expected to choose either forward or reverse rotation, protect against overloads and faults, and regulate the torque. Each electric motor is equipped with controller which has varying functions and features.
Motor controls can also help protect larger motors from overload or from having an over current condition. This is done with a protective overload relay or temperature sensing relay. Fuses and circuit breakers are also useful for over current protection. There are automatic motor controllers that come with limit switches to protect the driven machinery.
Certain complex motor controllers are used to control the speed and torque of connected motors. In a closed loop control system, a controller produces precise positioning of at motor in a numerically-governed lathe.
The motor controller accurately positions the cutting tool based on the pre-programmed profile. Likewise, it compensates for different load conditions and disturbing forces to help keep the tool’s position.
Motor controllers are based on what they con do. There are manual motor control, automatic motor control and remote motor control. Depending on the manufacturer, motor controls may only have a start and stop button. But there are many controllers that control a motor with many features.
An electric motor control can be classified according to the type of motor to be driven or controlled. These are servo motion control, step motors, alternating current or AC, direct current or DC-brush and brushless DC or permanent magnet.
Servo is a generic term for an automatic control system. In practical applications, it is a mechanism that you can set and forget. It adjusts itself during continuous operation through feedback.
Servo motion controllers are part of a closed loop control system for electric motors. The motors used in servo control are normally DC. The servo motor controls use a sensor to detect motor position and speed.
A stepper motion controller is viewed as an electric motor without the commutations. They are composed of permanent magnets on a rotating shaft called a rotor. The electromagnets in the stationary area are called stator, which surround the motor.
All commutations must be handled by the stepper motion controller, which comes in two classifications. These are permanent magnet and variable reluctance. The permanent magnet motors have the inclination to cog when you twist the rotor. The variable reluctance motor spins freely.
AC motors are affordable to build and operate. They are also reliable because they run from standard line power. The magnetic fields of this motor control are generated using coils on the stator and rotor. The field movement happens naturally in the stator because of the alternating nature of input power.
DC motor controls convert electrical power into mechanical. Permanent magnet DC converts electrical energy into mechanical energy through the interaction of two magnetic fields—one is produced by a permanent magnet assembly, while the other is produced by an electrical current flowing.

this looks a lot like the brushless motors model airplane guys are building from old CDROM drives, stacking armatures in a single can and custom winding the armatures.Tho with brushless your controller is in charge of timing which allows adjustable output and greater efficiency where this dual motor DC unit has to be physically configured to time correctly. Not bad if you have a machine shop handy and sponsors, electric vehicles used to have the curse “it's the battery, stupid” as the performance limiter. Now things are becoming ” its the controller, stupid!”. Finding a way to properly manage a minimum of 2 kilowatts safely and reliably and affordably is the new challenge.that, and of course, having enough electricity to charge your batteries, which Kalifornia has shown it's unable to do reliably at even current demand over the last decade-much less in the future.

It is because modern drives all have firmware running them, so when all the read/write heads and circuitry is missing, it will cause problems and go into shutdown. You are probably better off either find a really old (MFM) hard drive or just buy a brushless motor + controller from an RC car/helicopter site like xheli.com. You can be done for like $40.
