We mostly use Lori's Gen8 as a hiking trail buddy rig...... not much as a crawler. Most of us Ryft owners know it going to take a few extra hundreds to keep it running going in. I've got more in upgraded parts than I do the kit and I haven't even opened a bag yet to start the build LOL
They're top heavy, like to roll over all the time. I added sway bars to ours and it helped a little. We mostly just let the grandkids play with it on 2s till I trashed the servo playing with it in the snow on 3s.... I hear that they make great crawlers if you swap out motors/esc.
