Motor and Battery Combinations
The Flux Brushless System can handle a wide range of motors and battery types - please make sure that you use the right combination!
* When fitted with the Flux Warp 5700 motor or other motors with 5700Kv of power, you can use up to 8 normal NiMH cells or a 2S LiPo battery.
* When fitted with a motor with 4600Kv of power, you can use up to 12 NiMH cells or a 3S LiPo battery.
The term Kv refers to the number of RPMs that the motors will try to deliver per volt applied, and is a standard term for brushless motor power.

How Does Brushless Work?
- First, how brushed motors work
To know why brushless motors are so efficient and powerful, it helps to know how standard brushed motors work. In a conventional RC electric motor, such as what you find in the Sprint 2 car or E-Firestorm truck, you'll find two wires (positive and negative) that connect to specific points in the endbell of the motor, two curved permanent magnets inside the case or 'can' of the motor, and a spinning shaft with wires wrapped around it that goes down the centre of the motor can. The shaft and the wires together are known as the 'armature' of the motor, and at one end is where the motor pinion gear is attached - at the other end is a copper section, this is called the 'commutator'. The wires that come from the speedo bring power to the brushes, which physically contact the commutator, turning the armature into a basic electromagnet when electricity is applied.
- How a motor spins
When an electromagnet has power applied to it, one end becomes the north 'pole' and the other becomes the south pole. Because the north pole of any magnet is automatically repelled from the north pole of another magnet, the motor armature will want to spin so its north pole is facing the south pole of the permanent curved magnets mounted inside the motor can. As the armature spins around to make the north/south poles meet, the electrical charge applied to the armature flips, so the poles are again repelled from each other and they make the armature spin, turning the pinion gear and your car or truck's transmission. Most electric motors have three poles instead of two - this prevents the battery from shorting out, lowering efficiency, and it also prevents the motor from getting stuck in one position.
- The limitations of standard motors
The restrictions of brushed motors are made clear when you need to get huge amounts of power and speed from them. Because the brushes must remain in physical contact with the commutator at all times, there is significant friction from them, especially at high speeds. Any imperfection in the commutator makes the brushes bounce and lose contact, making the motor less efficient. This is why racers true the commutator of their race motors after nearly every run, and change the motor brushes almost as often. There is also significant electrical noise generated by the inefficient circuits, and the commutator and brushes eventually wear out, requiring replacement of parts of the motor, or the entire thing.
- Now, how brushless motors work
The basic explanation of a brushless motor's construction is that it is similar to a brushed motor, except everything is 'inside out' and there are no brushes at all. The permanent magnets that would wrap around the armature in a normal motor are instead placed around the motor shaft, and this assembly is called the rotor. The wire coils are around the inside of the motor can, making several different magnetic poles. A computer (the electronic speed control designed for brushless motors) handles the power getting to the wire coils, turning them into electromagnets as in a brushed motor.
- Why brushless motors are so much more efficient than brushed motors
Other than the ball bearings the rotor spins on, there is no physical connection at all, automatically making the brushless motor more efficient and longer-lasting because there is no friction of the brushes and commutator. Having a computer (the speedo) control the rotation of the rotor also vastly increases efficiency. There's no sparking from brushes to commutator, and the coils are much easier to keep cool, again boosting efficiency.
Why Sensorless?
Apart from basic size and power differences, brushless motors are available in two main types: sensored and sensorless. Sensored motors use an extra set of thin wires that connect the motor to the speedo, plus the three thick wires that give the motor its power. The extra wires tell the speedo the position of the motor's armature as it spins, hundreds of times per second. This provides a huge amount of data to the speedo, and the speedo's 'brain' takes this data and combines it with the throttle input from the radio system to make the motor spin as smoothly and efficiently as possible. All this makes for a great system for top-level racers, however it makes the speedos and motors a bit more expensive and slightly harder to install and use.
A sensorless brushless system, as you might guess, doesn't have these extra wires and the motor armature spins without relaying its exact precision back to the speedo every milisecond. This makes the motor and speedo easier to manufacture, simpler to install, easier to adjust and cheaper overall. A sensorless system provides the same amount of power as a sensored type, just with a little bit less precision - perfect for sport racers, bashers, general hobbyists and pretty much anyone that isn't a hardcore, world-traveling racer.
At HPI, we decided that our customers would almost never need the precision that is available from sensored systems, and we've chosen to use the popular sensorless brushless system for the Flux series.
