TamiyaClub member RA1028 have just posted more pics of the RERE Rough Rider! Mmmm...this is too awesome!!!
The use of LiFe battery is an interesting one because I believe it will be the first factory kit to include this battery technology. From what I've read, these are from A123 and one thing I love about those batteries are the incredibly fast charge time. I remember seeing that the packs can be charged in around 10-15 minutes. The only disadvantage is the larger size compared with standard Sub-C cells. However, even though the cell-to-cell size (A123-to-SubC) is larger, the A123 are 3.3V per cell while the SubC's are 1.2V per cell. Another thing is it requires a special charger, which will again up the price of this kit if you are using the included LiFe battery.

I've always been a fan considering 50% of my collection is Tamiya. But man! Tamiya just stepped it up with this rere Rough Rider! Please give us a nice white background boxart for this too!!!
[EDIT] Just pre-ordered mine through the hobby shop, apparently it's a limited edition. But I am 100% sure they will reuse the chassis for another model sooner or later, they wouldn't waste a mold just on a limited edition of one model.
