I have the Aftershock 8E and I have seen it jump 20' and 6' height in stock form. I have beat the crap out of this truck (curbs. tumbles, endos,rolls,flips,etc.) for 4wks straight til the steering link broke. At that point I did all upgrades to it except for the sway bars. That was in the begining, I just ripped my first body in half (the red one). Now I'll put on my new blue body. I wanted to see what the truck would do and take in stock form. It exceeded all my expectations. I have put some nitro fuel line on the shock shaft now for bottom out or a bump stop. This was my first truck after a 25 year absence from RC's.
