I know it's an old thread, but I'll add my 2 cents; I started with a Pro4 RTR for racing at my local 1/8 and 1/10 outdoor tracks (and 1/10 indoor occasionally too). It was great for learning to drive and I did eventually get a couple Podiums with it (after upgrading to a faster motor etc) but was itching to try something else. Now, please bear in mind that I'm trying to do this racing thing on a DAD BUDGET or I would've just dropped the cash on a Tekno rig like everyone else... I eventually scooped a used Losi TT Pro (basically budget/basher version of SCTE) from ebay and it was MUCH BETTER and easier to drive than the Pro4. I think the Pro4 was just too lightweight and getting thrown around/out of control too much- even after extensive performance mods. I sold off the Pro4 and started getting podiums with the TT Pro. Eventually added proper race electronics (HW XR8 and 4300kv motor), tires etc. and battled with the Tekno's every weekend. Never had any complaints about durability with either one, but the stock electronics in pretty much any RTR will have to be changed once you start chasing podiums. Can't see any way around that... Not sure I'd bother with a Traxxas if you want to race as I've never really seen one that's competitive. I'm sure folks have done it, but prob a road to frustration... For no particular reason I just don't want to race a Tekno like everyone else, and have seen my fair share of breakages/stripped spurs etc. from the Tekno guys while my Pro4 and Losi just kept on trucking. It was pretty rare to DNF due to broken parts and the 2 tracks I frequented didn't have an onsite hobby shop anyways... Plus it kinda seems like the newer Tekno's are basher type builds?? with tons of plastic parts and nosediving issues?? Idk. I'm now eyeballing a Habao...
