Tamiya Blackfoot Xtreme Project



Remember in the 90's when you could make things sound cool by spelling them wrong and using words like "Xtreme"?  Well, Tamiya was still doing it in 2003.  They had come out with the WR-01 chassis in 1999 which featured dual motors, four wheel drive, independent suspension, and big monster truck tires.  Then they decided to make a 2WD version called the WT-01.  This chassis was only used for updates of old models like the Bush Devil and the Mud Blaster, but the first to use the chassis was the new 58312 Blackfoot Xtreme.  So what makes this, the 4th incarnation of the classic Blackfoot, so extreme?  It has a hood scoop.  That's about it.  There is nothing to set it apart from the rest of the Blackfoot line other than this minor body detail and some rather gaudy graphics.  I decided to take mine a step further by performing the simple conversion to a WR-01 chassis so it would be 4WD.  None of the Blackfeet have ever been 4WD, but if any of them should be the "Xtreme" seems like the right one.  To power the dual motors I used the TEU-106BK dual motor controller.  With the extra torque of two motors I was able to increase the pinion size from 18 to 20 to boost the speed without worry of too much heat.

With the addition of some CVA shocks, this truck is super fun to drive.  Unlike its older cousins, it is easy to jump without worry of breaking anything.  With the 4WD conversion off road performance is excellent.  The differentials are still open so this is no crawler, but it plows through grass like it is not even there.

Update:  This model was destroyed in the 2022 fire.  It has not been replaced.
