This model is the first trace of TRF activity within Tamiya. The TRF211X is a prototype, and verify few were made (some say around 100).
This model later developed into the well know, and much loved, Dyna Storm.
The next time Tamiya dealt with 2WD competition buggies were when the TRF201 series began in 2010 with the 42167, ending (for the time) with the 42288 TRF211-XM.
All parts according to Tamiya Guide books, Tamiya manuals and Tamiya parts listings.
