TrackStar GenII 120A 1/10th Scale Sensored Brushless Car ESC (ROAR/BRCA approved)

For the price, you can find anything with good quality and powerful as this. Highly recommended.

If you're failing to connect this ESC with the Trackstar prog box start the smaller sized .exe under the folder USBLINK, connect the two devices and lastly plug in a usb cable. Works in Win 10 but might have to use another usb port and/or cable.

Excellent value, great performance, I run it in a TC and its as fast as anything else costing £££s more

I've used this in my Team Associated SC10 and SC5M 2WD short course trucks with 6.5t and 7.5t motors. It has been performing very nicely and has basically as much settings as anyone should need - though for changing those you'll really need the Trackstar Multi Function Smart Program Box.
The ESC seems to perform on par with my Speed Passion Reventon Pro 1.1, which is nearly twice the price. It doesn't even need to have the fan on with a 2WD SCT, and with the fan on it should be able to handle a 4WD SCT on 2S LiPo just fine. Speaking of the fan, it is REALLY loud, which is why I've been keeping it unplugged now.

I bought this esc a few weeks ago, and so far it's been very good. I've a few questions if anyone can help me? Is it safe to update the firmware? I've seen many examples on the internet of updating causing issues, such as the esc refusing to recognize the program box after updating. Also I've noticed boost will not work with turbo. Boost on it's own works fine, turbo on it's own works fine but both together and turbo will not activate. I'm running box standard V1 firmware. Thanks.

FIRST IMPRESSIONS: literally just finished putting everything together and took it out for a run (Tamiya TT-01 and Trackstar 7.5T motor). First: the fan is hella loud (but who cares?). Second: awesome low speeds even without the sensor wire. Bad things: it was a pain to solder (although it was my first time soldering), I couldn't connect to PC (but the program box works perfectly so I don't really care) and once when I went off-track in the grass it just turned off (it was probably the button). Turned back on, still works fine.
Overall I'm pretty damn satisfied with this thing. I will write a long-term review after using it a bit more.

I recently bought my second 120a GenII and had a similar problem. All was fine until I connected it to my laptop. After making changes to the programming and updating I could no longer use the programmer box or computer. I got a similar message "connection fail" Thankfully since it was new, it was replaced with only a photo of the problem under warranty. They didn't answer why this happened but I didn't ask specifically.

I have two GenII 120A.
I updated them with the last firmware (3.02), and now I can't access my esc
error message : "connection fail"
Plz help !!!!

This is my second esc now bought for the Basher RZ-4 paired with 13.5t Trackstar motor
and its just incredible....so smooth at low speed and no cogging just pure power and hardly any heat from motor or esc.

Recommend to anyone thinking of purchasing one.

Well what can i say about this little beauty.... 8 battery packs and still going strong
no smoke no bangs. I have turbo and boost set and it barely gets warm, so far im loving it.

Usb link or program box is a must! SkyRc bluetooth works too.
