The losi needs lunsford turnbuckles, titanium ball studs, & heavey duty shock mounts. All of this stuff adds up to around $100 in parts. Not to mention their product support has gone down the crapper. 3 years ago you could get a new setup to try once a week. Now you get one setup & it isn't any good. I have actually decided to run an e-firestorm this summer because it looks like the best all around truck to me, I come up w/ my own setups now anyways. It's a pretty bad day for Losi when the parts quality of rtr hpis has surpassed losi. 8 years ago a losi roller meant one of the most complete & high quality kits available. Well, things have changed & I am moving on from Losi.
