In all the races , I always testing out a few cars first with a slower motor and once they having no problems to complete the course.
After that I will change motors for a faster timings and boosting battery only for the speed track set up (when everyone started boosting it )hehehe
On that day, after a few tries on my car and change to hyper pro motor and it's came in the fastest time and after that I was setting my son car & my buddy car with boosting battery charge higher than the new battery charge and hopefully their can take that fast speeds...afterall u can see most of the regular racer's are boosting their batteries. My advice -not to any how boost battery it's might do more to your motor and also might damage
your car. Have to understand and observe the car performance..if not stable during the hump & change lane sections then dont keep boosting the battery.  
I am glad that you able come to Singapore in the September race and hope see you soon.     
No problem at all ! hope that our cars can races all the way to the top 10 position.

Hi 5WD,

I am not dragging any body and I have answer the questions to David ! n why you so offended !
Please read my earlier forums ok ! I always race my car with pride and I dont go around the world to complain whatsever is unfair.
By the way, are you been racing 4wd mini since Stargek started organize the races the past 2 years ?
As for me, most of the time is boosting back the used batteries back to their normal charge and this help to save some money on battaries cost...
and hope you understand this !
Dont you worry and I will answer all my actions that I have done as 4wd mini racer's.

Hope this forums is open discussions on 4wd mini car and please do not give negative feedbacks....
