I have the hobbyking gt-2 model (seems identical, just rebranded), and it at least has better range than a 2.4 traxxas radio I replaced it with. Had no problems keeping up with over 70mph and response/precision is way more than adequate for 'bashing'. I can say, though, that the plastic feels very cheap and brittle, and the wheel return spring is a little too stiff for my liking. Performance-wise, I don't really see why it couldn't replace a am or fm radio in a rtr vehicle, beside the fact that it lacks various adjustments such as end points. I also have never been able to warrant the price difference in radios to simply have the fastest response time in the top of the line systems. I mean, the speed increase is measured in milliseconds. The response one should be working on is getting their brains to transfer the signal to their fingers faster. Seems a lot of people today actually believe they need to have the best of everything to be competitive, and tend to shoot down any product in the market that even remotely focuses on value.
I wasn't even looking for a radio at the time (as I already had two spektrums and 2 older jrs) but I saw the price of it, asked myself if it could really be any good, gave it a shot, and was actually surprised. I kind of expected it to end up in the dumpster and only bought it because I thought, heck, it's only twenty something bucks shipped.

Umm, what does overkill mean again?
