do you have a link to that video? i'd like to see it in action as well. i figured it's based on a tough chassis so it should be fine. with that much displacement, i'd expect it to have tons of torque but not as many rpms as the .21 onroad engines. i'm looking for something that's tough as nails and enough ride height adjustability so i can drive it on the street with all its imperfections. i've tried driving my evolva on the street and it wears down the expensive foams way too quickly. from the pic of the inferno, the portion where the rear body mounts connect to the rear shock tower, looks like a potentially weak area. it's hard to tell from the pic tho.
