awesome!!!!!!

Drifting101 05-16-2008 03:20 AM

why couldnt you just post that in the thread that is already made?

gtypecanare 05-16-2008 09:09 AM

Anyway.....

Based on my information the hop-up parts should be released the same time as the kit. I'm looking forward to seeing our sample in the upcoming weeks.

like your signature... and you're already a victim of their marketing plan :p

anyway, if it share some parts with TA05, it shouldn't be too long before we see TB-03R i'd say 6 months to 1 year time.

other than that... it sure looks good and i'm always fond of shaft driven cars to race in 23T stock class.

bobbyvegas 05-16-2008 04:52 PM

WOW, It looks like I was right on about the Tamiya hop- ups for it. Looks to be stock EVO 5 shafts parts ect. from what I see..

hi doddy,
its been a long while....tb03 will use 416 susp setup & evo 5 drivetrain...perfect for 23t use.:D:tire:

yo Alan, been very long. i am no longer staying in the little red dot. how's things there. i'm looking forward for TB03 to arrive then i might want to use it for TAC qualifying ;) we'll see

if it uses 416 and evo5 parts then it can be hopped up straight away... more $$$ to spend!!

i like the look of it so far!

so no wonder didnt get to see ya around the track any longer...things still the same here, not much changes. you better go prepare lots of cash in hand, 'cos this car will suck them dry real fast...:lol::lol::D:tire:

thudtheace 05-27-2008 08:07 AM

uggg... Looks like another Tamiya Kit I'll have to buy. It looks great! Looks like an IFS chassis with a EVO-5 drive train. Glad they went with the sectioned drive-shaft(evo5 style) and we still have a protection on the gears. Looks like my new outdoor racer! Looks like this chassis will address all the issues in the Tb-02 chassis (i.e. stripped bevels, fixed gear sets, etc..)

Cheers!:smile:

magerp 05-27-2008 09:33 AM

I try to stay away from Tamiya cars (because my xray works so well), but this car is different enough to give it a try. I think I will wait until the R version comes out.

thudtheace 05-28-2008 07:07 PM

It looks like the Aluminum TA05-IFS Rocker Arm Set will fit the TB-03(can anyone confirm??). I suspect a number of parts from the ta-05 IFS and evo-5 will fit the TB-03. Hopefully this is the case as it will make my hop-ups cheaper since I already have most of the parts.

Real Cool:spidey:

Hebiki 06-04-2008 03:37 AM

release date?

redbones 06-04-2008 10:09 AM

I think it was 6/25

adrictan 06-10-2008 07:39 PM

Managed to get info from another Jap website. Shipping will commence from 26th Jun. Pre-order is accepted is including shipping to SG, it'll cost abt $330(Kit only)

alana07 06-27-2008 07:53 AM

the manual can be found at Tamiya Japan's site,

http://www.tamiya.com/japan/download/rc_index.htm


manual states that 46mm cvd driveshaft is used, but Tamiya USA option parts list that as 44mm???:rolleyes::rolleyes:
so which is which?

redbones 06-27-2008 11:09 AM

Interesting. I was worried about the size of the pinion that it can house, but seems it can go pretty big. I wonder what the limitation of the spur gear is. I run both 27T and BL, so I need a pretty wide range of gearing.

I can see the tamiya magic that is about to unfold with the option parts.:cry:
carbon reinforced A,K,M (M is pratically for the shock tower only) The chassis(big bucks), motor mount(maybe not as overkill as the TA05).
At least the arms, universal, and stabilizers fit directly from my IFS-R

UltegraSTI 06-27-2008 03:46 PM

interesting, gearing options?

R

thudtheace 06-27-2008 06:24 PM

Looks like pretty good gearing options.

With the stock 06 module/64T Spur the gearing can go from 9.75:1 to 5.77:1. With the pinion teeth ranging from 16T to 27T.

With the optional 04 module/96T Spur the gearing ranges from 9.36:1 to 4.58:1. With pinion teeth ranging from 25T to 51T.

This is straight out of the TB-03 manual from Tamiya's Japanese website.

Cheers,

Thud

Core Creations 06-27-2008 07:24 PM

From the looks of it, maybe a standard size spur will fit? ie Robinson, Precision??

redbones 06-27-2008 07:45 PM

pretty sure the standard gears will fit.

ittjv 06-29-2008 10:56 PM

The internal ratio is horrible for brushless racing. I hope tamiya releases some different gears and then it'll be on my list!

Just picked one of these up to compete in the Tamiya GT class here in Okinawa. Got all the hop ups as well (just waiting on the rear input shaft and CVD's as they sold out the day they arrived).

Looks to be a nice kit. I'm wondering how it'll fair in hopped up form against my TA05-R.

We shall see.

Ok, I like the kit it looks like a good Idea for GT2 in TCS, however I have been told that all previous TB cars has a problem, upon impact the teeth on the rear diff would ship. Does anyone know if this has been addressed.

RC MARKET 06-30-2008 06:54 AM

Tamiya TB-03 parts was arrived , but kit not arrive ??

Yes, it does happen, but you can prevent it. For shaft drive cars, you have to be very precise on the shimming of the diff and bevel gears. Since tolerances vary, you need keep adding/subtracting shims until you get a near zero slop drivetrain. You can do this by first adding shims to the e-clip that holds the bevel gear to the center shaft. Make sure that there is no slop here. Adjust the backlash of the two gears to the point where it's a little tight with the cover on, and then take out 0.1mm. ensure that is smooth, and that should be it.

Also, try not to be full throttle when you crash or being flipped over by the marshalls.

energyracing 06-30-2008 12:21 PM

Interesting, thank you.

Never had this reported problem with the old TC3.

Hebiki 06-30-2008 12:34 PM

are the internal gears for the TB-03 the same as the EvoV? EvoIV? interested to know which ones to get, esp for the front one way gear and the bevel gears. :nod:

The bevel gear part# is the same as the evo5. Even the new alum centershaft option works on the evo5/ms. Guess this car is a plastic version of the evo5ms with IFS. Don't know why the suspension blocks are all named for TB-03 when it can be used for pretty much all the cars.

Going to get this car maybe today or tomorrow.

sweet thanks. i hadnt had the chance to look at the instruction manual. :D

redbones 06-30-2008 03:28 PM

The only concern I have for this car is the size of the spur that can fit. The manual says 96T, but hoping I can at least get a 105 tooth in. But since the gear box is completely encased, I'm probably hoping for too much. Going to have to get more pinions...:cry:

i need to figure out how SMALL of a spur i can get in there :) with 13.5 and 17.5 brushless racing.. i need to get my FDR down in the low 3s. :eek:

gtypecanare 06-30-2008 10:56 PM

Chris, you should have drop by Tamiya this past Saturday, as we had our sample available to view.

redbones 07-01-2008 11:05 AM

Got my car today, and checked the size of the spur that can fit. unfortunately, 96 seems to be the largest you can fit. Still need to check the BL gearing limit, but the pinion area is big(tamiya states up to 51) so it should be ok.

But the shimming is PITA. The key is to first shim the diff so that it has near zero slop. Then shim the center shaft so it has near zero slop. Close the gearbox, mount it on the chassis, and then put the rear brace on(trust me on this). Check to see if the diff and shaft spins freely. If it doesn't adjust the lateral position of the diff by moving the shims left or right so you will get just enough slop. Need to check with the gear box closed so you have to open and close it several times before you get the right adjustment. I highly recommend tapping the screw holes so you won't end up with forearms of steel:lol: But when you screw everyhting down on the rear end, it is solid.

BTW, the chassis weight is 133g for TB03, and 149g for TA05, if anyone is interested.

foampervert 07-01-2008 09:32 PM

evo5ms and tb03
 
hiya folks,

the tb03 uses centre drive-line parts of the evo5; the evo5ms centre driveline parts are wildly different and are not compatible.

have fun!

-alexander

alana07 07-01-2008 11:46 PM

just did some comparing between 416, Evo 5 MS, TA05 IFSR and TB03, which are all basically using the same suspension components, all except TB03 uses same part #s for the susp arm, knuckles, C hub & rear hub. so are these parts on the TB03 made of a different material, hence different part #? anyone who hapen to have a TB03 now and any of the above cars make a comparison of the material of the parts? thanks...:sweat:

aww you should have told me sooner. i was at BCR working on my 416. is Tamiya open this sat? havent seen you in awhile. hope things are good. :nod:

energyracing 07-02-2008 09:43 AM

So why should I buy the TB03 over the TA05 IFS?
