Totally agree with what the guys are saying
I've been racing now for about 7 months with the club and love it and I've gone through so much changes. Car, electrics, ect
I have the same sensor less system you had but when you change to a sensorsed system, you'll never look back.
With what si was saying regarding the turnigy batteries and the trackstar motors, these are really good and cheap but good quality.
I used a turnigy trackstar 6.5 weekend just got and it could keep up with the fastestest cars, and for £25 delivered from uk, in my opinion you can't go wrong. A few guys run these
The batteries are turnigy nanotechs and like si said, do the job the same as the more expensive sets
If your on a budget, I'd say these are good (others may disagree lol)
