Very useful and super easy to use. This programming card is a must buy if you have a Racerstar ESC because by default the "Start Mode" is set to Medium and "Brake Force" is set to 100% on the ESC which is too much and the Start Mode set at Medium creates motor cogging if you have a heavy RC car. I usually keep mine at Start Mode - Strong and Brake Force - 25%. By the way, I can confirm that this programming card works with these two ESCs for sure: https://www.banggood.com/Racerstar-60A-ESC-Brushless-Waterproof-Sensorless-110-RC-Car-Part-p-1085233.html?p=LN24205151027201606U and https://www.banggood.com/Racerstar-60A-ESC-Brushless-Waterproof-Sensorless-With-Fan-110-RC-Car-Part-p-1116663.html?p=LN24205151027201606U

لقد كنت قلقاً عليه في البداية حيث كان هناك ضوء أزرق وامض ولم أستطع فعل أي شيء بعد ثلاثة طاقة على الضوء الأزرق قد ذهب ونجح.

I was but worried about it at the beginning as there was blue flashing light and I couldn't do anything. after 3 power on blue light has gone and it worked.
