its cool and all but at that size you pretty much arnt driving an RC anymore. Its cool, its pretty BA looking but like i said ages ago. I think 1/5th is the largest scale i would ever consider (or 1/5th-ish, +/- a little is fine). The thing is you can put a 46cc in these and its well over powered, you need a monster of an engine for that, you would essentially be working on a car.
Besides, what would you do with it? you cant really take it to the park and run it around the local baseball field, other than MX tracks there wouldnt be anything big enough to handle it other than the desert. And who would make parts? Rich people toy, IMO. Not powerful enough to enjoy like a smaller scale and to large to take anywhere. My Baja fits the trunk of my Skyline, with a little to spare. Any larger and i wouldnt be able to take it with me without another car.
