Hi, I hope what advice I can give is looked on as helpful and nothing else.. If I was looking to give the buggy a boost I'd go for lipo batteries, the weight(or lack of..!)compared to Nimh will give the car better top speed, increased acceleration and better run times on the motor you already run... As for BL motors, they are not all ballistic.. In fact I'd say with the lighter lipo cells you could go for a 13.5 and gear the buggy up a little, say 2-3 teeth greater on the pinion, this could help the pace and feel of the car...
