I'm curious about getting an Arrma and I'm not really sure which model will suit me the best. I currently own a 1/16 Traxxas mini revo and a Traxxas Slash 2wd. And my son and I mostly drive that around the street and some small ramps. I'm curious about getting something I can run in the backyard. I have an acre and the grass is fairly thick and usually mowed at the highest lawnmower setting (4.5in I think). So which model would be the least expensive model that would be able to handle that terrain? Am I looking at a 6s Kraton? Or would a Krayon 4s handle that fine? What about a 3s granite? I'm guessing the 3s Typhon is out and probably the Senton as well? Basically I'm looking at the list of BLX vehicles and trying to eliminate some from contention while staying as inexpensive as possible. Thanks!
