1 x HobbyStar LCD Program Card  



A complete 1/10 competition power system featuring a HobbyStar 120A Turbo ESC, 540 Sensored Competition Motor and LCD Program Card.


The HobbyStar 120A Turbo ESC is truly the next level in 1/10 competition speed controls. Offering an unprecedented level of control over boost and turbo-timing features, this ESC gives you multiple timing adjustments to control power delivery and maximize vehicle stability. 


Any ESC can put down the power, but what sets the HobbyStar 120A Turbo ESC apart from the rest is the control you have over that power and braking action. Both the punch-rate and brake-rates allow you to select 2 separate stages of adjustment along with a switch-rate (the point in throttle travel at which the second stage setting is applied).  This is an invaluable tool for fine-tuning your power and brake delivery to not upset the handling of your car by controlling wheelspin under acceleration, and tire lockup under hard braking.


Boost timing offers an optional “Stability” mode which regulates boost timing not only by motor RPM, but by throttle position as well.  Additionally, boost timing can be set to “Linear” (boost timing is applied increasingly based on RPM), or “Custom” (freely program the amount of timing at a given RPM).


Turbo timing can be activated by RPM, throttle position, or a combination of the two, and the rate at which it is applied and pulled back (turbo “Slope”) is programmable in order to maintain vehicle balance and not upset handling.


With an extensive list of other programmable features, “Blinky” mode for stock-class racing and a beautifully machined T6 billet-aluminum housing, the HobbyStar 120A Turbo ESC is THE choice for 1/10 scale competition.

NOTE: This combo is best suited for 1/10 2WD buggies, SCT's and 1/10 4WD buggies.  NOT for use in 4WD SCT's.

Excellent choice.Review by Gopro85
A couple of my friends had this combo before I purchased it and I thought to my self, how could a motor/esc combo with a program card this cheap perform as well as they were claiming it did? Well let me tell you, it surpassed my expecting by far. This motor and esc combo is flawless. So many program options, cheap price, great quality, and not one complaint. This is a perfect combo for a lot of aplications. (Posted on 9/2/2016)
$150.00 Bomb ESC/Motor/program box Combo for B6D BuggyReview by Kotipelto
When I received this combo I was extremely impressed by the quality looking parts. I live locally and placed my order early and received it the next day. You really cannot go wrong with this deal. It screams quality. Motor comes with the updated soldering posts similar to the tekin stuff. Calibration of this esc is simple and painless without having to push any other buttons to set neutral/forward/reverse .The instructions are all English, well thought out and easy to understand. I really like the purple led on the on/off button that is located directly on the esc housing itself. When calibrating mode is set it turns blue and red. I installed in the AE B6D buggy and could not be happier and John's CS is second to none. Very Nice combo that does not break the bank. Impressed! (Posted on 7/15/2016)
