I need a little help in making a decision please? I am purchasing a new /used rc truck for my son and I . I just don't know which one to get and need your experience to help me make that decision please? I have 3 vehicles to choose from 2 in the same price bracket . 1- lightly used e-revo brushless. 2 - slightly more used e-maxx . & 3 - (slightly more expensive tho )arrma outcast 4s. The e-maxx I think is brushed where as the other 2 are brushless . Not sure how much the upgrade would be for the 2 brushless motors on the e-maxx. Or if I should just go with one of the other 2? The outcast is 90$ more than the other 2 ,not sure if it's really worth that much more? Please help . Thank you
