Brushless, Lipo Cr-01 build

[rootar]

im just looking for something to dork around with, plan on putting my grandpa's new rock patio/ rock garden he is building to good use, i cant decide between the two, the CR-01 looks so awesome and from what i read crawls better than any one would think it would, i know the AX-10 is a good platform and it is 70 bucks cheaper too.... what kind of runtime you getting with the brushless setup and the 5000ma cells?
