Would have prefer to spend abit more on the more established brands, such as speed passion, hobbywing and such. Have used hobby king previously, and am saddened that their tech support is almost non existent, and their esc does have QC issues at times. Have experienced first hand whereby it either last u a long time, or sudden death. Switched over to the established brands and no issues as of date.
Personally have stripped out 2 trackstar motors due to excessive free play of the rotor out of box, and realised that it's not shimmed properly as comparing to one of my old trackstar. Pretty disappointed on the QC.
