I personally have the RC10GT, but also thought long and hard about the Losi XXX-NT. I have driven them both, and know people who also own both, and basically, they are the best out there. One over the other is a personal preference. I like the AE, because all my other RC is AE, and I think they are unbreakable. Although Mugen makes a great product, the MST-1 is alot more expensive, and you really dont gain anything. As far as the Kyosho, stay away, I would buy a durtrash before I gave a dollar for that piece of crap. They need to stick with making buggies. Hope this helps.
-Steve its not a crime, bmoc2008 ment your opinion was neccesary-
-The Gt has loads more hop ups than the brick, rock, hustler, whatever you want to call it.
-The Mugen has alot of hopups included in the box.
-Don't get a duratrash
just my .02
Its an opinion, some people like GT others like NT just try one. If you want RTR the Sport is the better deal with the JR radio and such. If you make it from a kit you will have to see which is better. (Flip a coin or something)
I forgot that the xxx sport has a JR but that AD edition hauls some major ass. I agree with steve flip a coin or like choose 3 and roll a dice er somethin its all personal opinion
