It seems every year this comes up on a message board (sorry Pete). Tamiya/TRF missed the boat when Kyosho came back with a 2WD contender (rb5). Seriously, how hard is it to make a efficient 2WD tranny

??? Just copy the B4, would not be the first time Tamiya has copied another company..
Tamiya will stick to what they do best recently - keep releasing the re-res, sell TRF kits with minuscule changes and keep creating many variations of the TB03 and TA05 chassis' to pump out new kits

.. I will not hold my breath
