I'd go for the TA03, its good for touring as well!

TB03R is a great chassis, just the price of the TRF Shocks is US$45, add that to the US$160 of the standard TB03, one or two other hopups and you are in the US$200's...you get no ESC, Motor or body kit though....so they start evening out. Still a good car though. I would buy one but I am working out if it would be better to get the std TB03 and then get the upgrades I want....because they differ slightly to what is in the R kit....

If you want to use a BL in the Touring class (25T or 13T BL) then you could easily use your TT-01 ....what upgrades have you done? The minimum I would do to get a decent tourer is as follows
Alloy Prop shaft and joints
Oil-shocks (not necessarily TRF's)
High speed gear set
Steel pinions
Adjustable upper arms (front def, rear if poss)
Steering link upgrade
Team Sorex 36R tires
Bearings (obvious)

With that setup, a TT-01 would be very competitive (I think Pauls is similar to that and it goes really well)

All of that new would be more than a std TB-03, which out of the box, is very capable...

The TA03F is vintage....let her rest also, they are the same as the FF01's, you know what the problem is with hot motors in those...

.....or buy that TB Evo 4 from Vinesh......best value for money EVER......

...parts are still available, a little scarce.....but still available....

TRF cars are designed by the racing department, using racing R&D....the value cars are copied from them; so TB03 is a copy of the EVO5 in budget parts, materials and design criteria. TA05 is a copy of the TRF415 in budget parts, materials and design criteria.

Things like the TT01's, TL01's etc are all a product of the normal tamiya R&D

Think Vinesh still has a Evo 4 sat in the LHS in Deria. I nearly brought it, in fact i prob would have by now but havent made it down to the store as ive had no free time from work.

LOL so Vinesh IS Hobbies Zone then......

Haha i think they are just selling it for him and making a margin on top. I think ive been in there when one of the investors/owners have been there.

aha! so it IS true!
