I know there are few folks who play with Rc cars and what not...I couple of days ago I bought my oldest an ECX Ruckus truck which is really awesome and he loves but I also bought this little 1/18th scale EXC Smash.
The Ruckus is very cool and I really like it but the little Smash is freaking SWEET and a BLAST.
Battery lasts forever (I've actually only charged it once and been driving it like crazy) and the little thing is a rocket.
2WD 1/18 Smash Monster Truck Blue (ECX8400): ECX RC
My son almost wants to trade for the Smash and give me the Ruckus.
The only complaint is the radio is 27 Mhz and not 2.4Ghz. Still - worth it at $80 RTR.
The Ruckus is excellent as well and RTR is 2.4 Ghz, waterproof and pretty quick. Both come with NiMH batteries which suck but they work well in the smash and okay in the ruckus. I have some Lipos ordered for the Ruckus.
