The ECX Ruckus is a good entry-level vehicle. They have some hop-up parts but not as many as there are for Traxxas vehicles. Traxxas Stampede wheels will fit on the Ruckus.
The 2wd Brushless Ruckus sells for $300.00. The 4wd Brushless Ruckus sells for $330.00. They run good on the NiMh batteries but if you want more power from the BL motor then you can move up to LiPo batteries. That move will cost at least $100.00 for a battery and a good charger.
For a some more money you can get a Traxxas Stampede. A little better built and many more options for parts; standard Traxxas replacement, Traxxas upgraded/aluminum, RPM upgraded, and Integy aluminum parts.
The 2wd Brushless Stampede sells for $340.00. The 4wd Brushless Stampede sells for $450.00.
The Stampede runs fine on the NiMh battery but really goes with a LiPo battery .
With the Traxxas vehicles you do not get a home charger,only a 12v car charger. Plan on spending around $40.00 more for a basic home charger or get a better charger that can charge both NiMh and LiPo batteries.
Good Luck.
