Not all speed controllers are created equal. The TrackStar 120A GenII ESC is an evolution of previous designs and a true thorough breed in the TrackStar stable. Designed and tested under race conditions the 120A GenII ESC is ready to stand up to the high demands of competitive racers. The Trackstar engineers designed the 120A GenII ESC with one goal in mind, creating an ESC that would offer performance, reliability and endurance when placed under pressure.

The TrackStar 120A GenII ESC offers a host of programmability options that most racers have come to expect and depend upon. Programming can be done trackside with the multi-function programming box or via PC with the TrackStar USB Link software.

Timing Indicator LED (Blinky Mode)
For future conformity with ROARs Sportsman Class racing rules and to assist race organizers to monitor driver compliance in non-timing modified race classes the TrackStar 120A GenII ESC includes a timing mode indicator LED. At all times when the ESC is powered on and dynamic motor timing is set to a value greater than zero the white LED will illuminate indicating that the timing mode has been modified.

For a winning combination use the TrackStar 120A GenII ESC with our proven TrackStar 1/10th 540 Size and 550 sizes “Red Can” motors for a package that leaves the competition in the dust on performance and value!

Great ESC so far

Oct 22, 2019

I paired mine with a Trackstar 5T 550 "red can" in my Traxxas Slash 4x4 powered at 3S and it's got huge power. I purchased a program box off ebay where there are lots of them for sale and after a firmware upgrade everything linked together great. I had to contact support for them to send me the "OK" version of the software found on the program box's page since the site is broken and wont let me download them. Programming options are great through the PC, so great that I probably won't even bother with only using the box unless I am at the track. The fan it comes with is pretty insane and very loud but it seems to get the job done quite well. However the RPM is so ludicrously high that I don't expect it to have the greatest lifespan so I already ordered a replacement 25mm WTF fan which fits the spec of the stock one perfectly.

При учете отсутствия возможностей настройки - мусор

Sep 14, 2019

Первый такой регулятор я заказал 4 года назад.
Он прекрасно работает по сей день.
Недавно мне понадобился еще один регулятор, но здесь оказалась проблема.
То, что когда-то работало, перестало работать. В конечном итоге я имею мертвое тело за определенную сумму денег.
Регулятор не видит карту, PC не видит его так-же. В итоге мы имеем кирпич, который годен на роль памятника.
Очень хороший брелок для моделиста, всем рекомендую =)

Good value but prgram box sold by hobbyking does not work

Sep 13, 2019

Good ESC....but the program box sold by hobbyking often doesn't work for many people, thus requiring a software download that also often doesn't work due to compatibility issues. Only buy this ESC if you are satisfied without the ability to change settings, works straight out of the box at least. Don't waste your time with support...unfortunately they likely wont be able to help. If you are strong on IT then maybe you can get it to work.....
