its hard to explain or decide something like this on a forum, you'll get too many opinions. i say get the hyper, it handles like a buggy and is not as heavy as its been rumored to be. but then again the jammin has been winning a bit more races a bit longer too. theres not too many hop-up parts for the hyper, where as the crt has many. i've had some diff issues with the hyper (my fault) and broke 1 front lower arm and a shock screw. not sure about the crt though and its toughness. i can tell you the hyper will turn inside a crt all day thoguh if you like that kind of stuff.
