This is the HPI Flux Q-Base Brushless ESC. The Flux Q-Base Brushless ESC is one-half of the Flux Brushless system that is fitted as standard equipment in the Savage Flux 2350 truck, forming an unstoppable power force for amazing off-road power! With the ability to handle twin 2S LiPo batteries (that's 14.8 volts of LiPo power!) it can handle anything the Alphastar 2350 motor can dish out! 4mm bullet connectors secure the motor wires for loss-free connection to the 13-gauge wires, and to connect to each battery pack HPI has attached real Deans connectors for zero power loss and total efficiency. Why re-invent the wheel and release a new connector when the best is already available?

Topping off the versatility of the Flux Q-base is an integrated cooling fan, which allows the electronic speed control to operate at its ideal temperature. You also have the ability to easily connect it to your computer for total programming control! With the HPI100573 USB Programming Kit (sold separately), you can connect the Q-base to any Windows-based PC to control all the various facets of its power delivery, braking, throttle curves, battery cut-off and much more. You can also save various profiles to have profiles for racing, insane speed runs, stunts, fun running and more.

When combined with the Flux Alphastar 2350, you get power optimized for 4S LiPo batteries, with custom tuning thrown in for fun! You'll have to experience it to believe it!
