So far i have been looking at:

6000KV Motor

OR                    (Dont know which to choose for a 2WD off-road mad monkey)

4000KV Motor

60A ESC

AND

3S RCM

2S RCM

2S GensAce

Im not bothered about the softcase/hardcase situation, what i want to know is which motor to choose and which battery to go with it, i will be using an IMAX B6 charger.

i'd go for the 4000kv it would be a bit mental with a 6000kv!!

4000KV it is, what gearing would you suggest? (Current Pinion/Spur is 21T/86T)

12t motor around 37000 rpm

a brushless motor will have more power so about 4+ more teeth but it will depend on the temps of the motor. if if gets hot it will need more teeth. a 4000kv motor on 2s will do just under 30,000 and so if you run it on your current pin and spur it will be slower

wouldnt i need less teeth on the pinion if it gets too hot?

[Jumper]

normally it's going too fast or over revving which means it needs more teeth

I'v just got the gensace 3s 3000mah lipo and its great, came with a perfect balance and I have had 2 cycles with it and its superb

the others have good reviews on that website also
