These things work pretty well as is, and since they show a lipo in the promo pics, there is no balance increase. Maybe with NiMH and saddle packs the argument could be made for balance. But that is still WELL beyond what I would want to spend on a chassis, especially since I usually have to buy stuff in pairs and am on a shoestring budget.
Heck, the cost of that chassis is the same as getting an 18R for use in the stock class.
Phil, there were some guys talking about this chassis on RC Tech, and the Exotek guy (Mike)as well as Tony Phalen (Associated) said that this chassis would not work for off road, because its made to fragile to take the jumps. They even mentioned that it would not be supported for warranty if its used on off road.
Of course, It can be done, but at $140.... wow
