Just A quick positive review on the 120a Trackstar. I've been using it in my 17.5 2wd buggy (also a trackstar motor which is an animal!) and have had great success. I did have some reservations at the beginning but not completely convinced and would not buy anything else. Runs cool, programming is awesome and not a single issue with anything. A heap of guys at the track are supprised at how well it all goes, most people are almost disappointed how well it goes compared to their very overpriced gear.
10/10, would do.
