So, some were asking why go from saddle packs to a single pack, then back again? After looking at the changing designs of all the vehicles, it seems like they keep going back and forth. If you think about it, there's really not that many big changes you can make to a vehicle. They keep changing the material of the parts back and forth and making the arms longer then shorter. Belt drive then shaft drive. Move the motor forward then back again. The biggest change they made in the industry was changing the 2WD class vehicles to mid-motors. The next gen Inferno will probably be designed for a single pack again and the other companies will make theirs saddle packs.
It drives me crazy when they change the chassis materials. Aluminum is best. then it's graphite and Carbon Fiber is best. NO, FRP is best. Not really, because aluminum is better now. The newer models are coming out with Carbon Fiber chassis again. The next big thing will be balsa wood.
