the tb-02 is better value than the tb-01 as you get ball diffs front and rear + bearings. Think plastic tub evo 3 so its a current model. I'm pretty sure its lighter than the tb-01 as well.
the tb-01 is probably better suited to rally duties as the tub can be fully sealed and has no gaping holes in the tub unlike the tb-02. also of note is the drive line is cast steel and straight out of the tg-10 nitro. included with the rally versions of the tb-01 is a dust cover with two drivers on the top. this cover may overheat your electronics.
Well I managed to find out that the tb01 is discontinued, so i'll prolly get a tt01 and jack it up or somethin. I also went to a local hobby shop that will remain nameless and the dude behind the counter reckoned the car was not available and there is no way that the Kyosho Alpha 3 Subaru Impreza WRC with rally block tyres on it could be driven in offroad coz as soon as you hit a rock (how big I don't know) that's the end of the car. Pfft as if.Edited by: RiZZa
Should still be plenty of TB01 kits left on shelves; although the TB02 is out its not a direct replacement. TB01 Rally Chassis still has very much a place on the Tamiya lineup so it'll be a while yet don't worry.
Parts are no problems as many are shared with TG10. Knowing Tamiya they even support old cars that have been looooong discontinued... like the TA01/02/03.
Even the TL01 is supposedly "replaced" by TT01 but they're still selling it alongside.
So I shouldn't be too worried about the parts situation ? I guess I should contact my nearest hobby shops just to make certain I guess. While I am hard on cars, (I planted my stampede at full steam into a steel pole at full steam on the first day) I witnessed a guy at the local sk8park launching an old ff02 mondeo on a concrete tabletop and getting 4ft of air without any damage 20 times and speaking to nismospeed about how he treats his, is why i want a tamiya tourer.
the front shock tower is a bit fragile on the tb-01s as many owners including me have found out. if you do break it you will be happy to know the front shocks can be attatched to the points where the front shock tower attachs if need be.
to reduce the chances of you breaking the front shock tower. fit the the large plastic bumper from a tg-10 and the foam bumper that goes with it and you should be fine.
here's a old pic of my tb-01 with tg10 plastic bumper and foam bumper. you will notice the front shock tower is not on the car cos i broke it
If you intend to rough-use your car, suggest TB01 is a lot tougher than TB02.
TB02 is a lot lighter built. Its tub doesn't have the upper brace and is more wobbly than TB01. Shocks are oil but strangely Tamiya has specified "super-mini CVAs", dunno why!? these have the least oil volume of all.
Suspension bits (from TA04) are long and flimsy... I've broken heaps of TA04 arms but have never broken any on TL01/TB01/FF02. Hingepin mounts are plastic & breakable, hingepins will bend & bind if abused.
Drivetrain also... TB02 has balldiffs sure, but they're cheapo versions of the EvoIII ones. Plastic outdrives will break or chip if you whack the front end hard.
Best thing about TB02 is the battery tray, can use side-by-sides. TB01 only takes sticks and mine damaged a lot of my batteries from impact damage.
Don't worry about TB01 parts... you'll be able to find them even in 2010, probably even 2015 if not beyond.
you can get side by sides into a tb-01 but its a very tight fit especially with gp3300's. for rally purposes i'd still go the tb-01 even with a weak front shock tower. for those that can be bothered looking, gpm and penguin rc both make CF shock towers for the tb-01/tg-10
