This kit looks very nice. I'm still a noob with my HPI S2 brushed kit bashing around a course we set up at work. I have been looking at upgrades for the S2 to get rid of the steering slop so that I can play with the alignment but it would actually be cheaper to just get this kit than try and get the S2 close to these standards. I just don't know if I'm too much of a noob for this type of kit. The RTR kit suits my skill level and the time/money I have to put into it when things break. But I would love to have something a little better with no slop and better precision.
