I have an airtronics 359 and 200oz is just hype. Once that buggy is throttled back, there is almost no friction on the front end. I might ruffle some feathers, but I can't tell too much of a difference between the 359 and my old hitec 645mg (on the track). That .10 sec isn't as fast as I would like though so I might go for something in the .07 @125oz.
