The Flux Brushless System is HPI's answer to hobbyists and racers who want a powerful, versatile and affordable brushless motor system. The Warp motors are extremely powerful, very durable and highly efficient to get you going on the road to victory! HPI Warp motors are sensorless type motors, so there are fewer wires to worry about, and less hassle for you. You can get the Motiv ESC and Warp motor in a set, or buy them separately to outfit all your electric vehicles with brushless power!

Future-Proof Upgradability!
Flux Motiv owners can update their speedos with a convenient computer link and free software download! Programmers are constantly making updates to the software loaded onto the Flux Motive speedo, and you can keep up with them by getting the Castle Link USB Programming Kit. This kit allows you to connect your speedo directly to your Windows PC to save profile settings, customize racing profiles, update the speedo software and more!

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.

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.
