wow, all i can say is argo recommends going backwards down steep hills. the video i got with my 6x6 goes through different driving conditions and that stood out in my little mind. i also recall someone here mentioning that careful use of the brakes going down hill due to foward momentum or you could somersault foward. going up doesn't concern me at all but descending does. what i have noticed while operating my bigfoot is that i take it slow and controlled, not crawling but not in a hurry and finding i need to jam on the brakes and getting into that somersault condition. i haven't descended backwards yet due to being careful and cautious. this is the other big difference between aatv's and atv's, sitting firm on the seat compared to being able to stand and shift my weight as on my yamaha raptor. i'm probably not adding much to this discussion except this there is a real learning curve to these machines and caution is key till you learn the machines limits like anything and practice makes perfect. i will say this though, i have not felt my bigfoot wanting to tip foward due to braking on a descent yet. i also feel argo's recommendation of descending backwards is wise till comfortable, better safe than sorry. i would also argue from experience that due to weight distribution, motor position, climbing out of the water on muddy banks can be eased by backing out. i got stuck once trying to climb out foward and just dug the machine in going foward. no winch at the time and i was in a jam. it was by luck that my nephew who wasn't good with the laterals and driving backed it out and it climbed right out, lesson learned. motor placement , weight distribution, is the the big thing in performance between the max and argo. both equally capable machines but both have a slightly different learning curve as a result of motor placement. no argument here as for who is better, i like both, more a comment on driver education to his machine and respecting it and the condition using it in. as a flight instructor i tell my students the same thing and it's part of the first lesson, respect the machine it can hurt you in a heart beat. learn it's capabilities and it's quite a tool and so much fun. long winded but i hope you get what i'm trying to say.
