RE: hyper 7
Stay away from the Sport and the regular Hyper 7 RTR.
Get either the Hyper 7 PBS RTR (I have) or Hyper 7 PBS/PCR RTR or Hyper 7 Pro.
The sport is lacking a lot of important hop-ups to be a real contender right now. The RTR has some, but not enough. The PBS and up is where it is at. I love the Hyper 7. My favorate RC out of the many I have owned.
