Most people diss the smartechs because they are cheap knock-offs of other, better vehicles. And the smartechs are cheap, and poor quality. And, I doubt you'll find ANY hobby shop out there that carries parts for them. I had a friend who wanted one, and had convinced himself that they must be good since they even exist. So, he bought it thinking he got an awesome deal. Well, upon arrival, it was in the OEM packaging, and needed a lot of assembly (3 hours worth) and it was advertised as a RTR. So, he finally gets it ready to start, he starts it after a lot of trouble, and drives it down his driveway, and off the 4'' slanted curb and breaks a shock shaft. After 2 weeks of waiting for the part, he installs it, then breaks an A-arm going up that same 4'' slope doing about 10mph max. So, he gets pissed, and says to hell w/ this. So, we decide to see how it would fair over some big jumps (we know it would break), well, we break 2 more shock shafts once we hit the ramp, then upon landing, the chassis gets bent, and breaks a shock tower, F/R bulkheads, 3 driveshafts, and even manage to crack a lock-nut in half. And, it got about 3' of air. So, he thinks o well, all rc's must be like this. So, I go get my savage, take it off the same ramp doing 30, do a backflip and a half causing an ugly landing and does 8 cartwheels, and keeps on goin.
Need I say more?
