What are people's experiences with these assist features by Traxxas, Losi, and others? Beneficial or just a gimmick? And I mean for bashing and driving around for fun, not racing where I can see there being a problem. I've been out of the loop for a bit and haven't tried these features, wondering what people's thoughts are. Specifically for 5th scale like on the Losi 5ive-T, but interested in how these systems work across all scales.
