lipo/brushless advise plz: sensible

[mcd_racer]

Thanks for looking.
Im currently running in the dark age's, a 27T t/c with 6 cell.
The common 4200 battery size that everybody appears to use, doesnt fit my chassis (cell diameter etc).

Solution: NEW CAR ,plus battery's etc. Cost increasing

alternative: LIPO or cell battery to a BRUSHLESS system.

Starting from the beginning, class me as a beginner to the new brushless technology

What do you people out there run with:

Battery/lipo type - motor- esc etc etc.

Getting confused with 13 and 19.5 terminology, soif you cantell me what combinations you are using.

Cheers Andy
