In my opinion the Traxxass is just terrible, Arrma wins hands down on anything speed related.!! (and maybe the new Hobao)
I'm not an Arrma fanboy, yes I have a fair few of them but currently I can't stand the company and the direction they are heading in.
What with them discontinuing the Rollers and then taking them two years to re-release the 4s lineup, that's not how to win fans !!
Also HPI no matter how cool that Scooby looks at the end of the day it's HPI and their days are done vs the likes of Traxxass and Armma, and on the subject of the new Infraction, for a box stock 3s rig nothing in my opinion can touch it for speed, parts, upgrades, looks etc etc
When I returned to RC a few years ago I re-entered by buying the 3s Arrma Senton and it blew me away at how robust and fast it was out of the box.!!
