Honestly concerning the whole 2S lipo thing, i don't think ROAR thought that the class would go the way it did with 1/8 based conversions like the SCTE (yes, I called it that, when you have a sister vehicle that is described by the manufacturer as a 1/8 buggy, yup, its basically a conversion then), Tekno, and others. The vehicles in turn push the limits of the batteries, etc.
Personally, would have loved to see say a 3S limit, and an upper weight limit thrown into the mix. Could give manufacturers the chance to get some money for those 3S hardcase lipo packs they make. Wouldn't give the as crazy torque as the 4S setups can offer. And, we could then all benefit with cooler running gear. Just my 2 cents.
Anyway, looking forward to the ET48. Truggy used to be huge out here, and it for some reason, I actually liked the looks of the vehicles lol.
