I live in Southern California and I have yet to see somebody race an X-Ray buggy at my local track. Everybody runs Associated, Losi (config'd for rear motor), HPI, or the occasional Kyosho. I'm the only one with a Tamiya. Maybe that will paint a clearer picture for you guys wondering what the West Coast of the US is doing in terms of amature R/C racing.
I do see a few guys with X-Ray Touring cars but never a buggy. I think I might have seen an X-Ray truggy once. X-Ray seems to be more popular in 1/10 touring and 1/8 off road, but I have never seen an X-Ray 1/10 buggy live and up close, ever. Thats the blunt honest truth. I'm not saying its not a good design, I just have never seen somebody bring one to the track. Nobody here is running center motor, thats why I asked what the advantage was. Now I know why nobody is running center motor over here. All the offroad tracks in SoCal are small with loose grip dirt, tight turns, and BIG jumps. If we were running big tracks on carpet, or high bite clay with long sweeping turns and moderate to small jumps, well then I guess we would all be doing the same here like you guys are doing in Europe (center mounted motors), but we run on the small loose dirt tracks with BIG jumps. I guess thats why Losi came out with the 22. They came out with it for you guys, because we dont need a center mount. Everybody here runs theirs to the rear.
Thanks for the youtube video Mof.
