Other than the Grasshopper and Associated RC10 I had over 20 years ago, the only one I own is my e-maxx (for now). I love it. I tend to beat the ever living snot out of it and found almost every out of the box part not up to par for my needs. So I reached into my pockets and upgraded!!! and the assebly of the upgrades to me is just as much fun as driving it... well almost anyway. I know in the future I want to build a custom maxx crawler, 2.2 clod axle crawler, and build a truggy. I'll probably go with a 8IGHT-T BL rig for that. however that is a few years down the line. The wife said 1 a year... and next year is definatly a BL maxx crawler.
