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.

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...

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.

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

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 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.

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!

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...

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.

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

redbones

Well, let's see. The TB03 is about 30g lighter, the battery is more towards the center, and much more direct in throttle responce. I still need to do a shakedown, but it seems to have an advantage over the TA05. I hear this EVO layout has quirks in the handling characteristics, but things are a little different such as the plastic tub(flex) and the IFS. We'll see. I suggest driving a TC4 or Pro4 to get the feeling of a shaft car.

I use to own a TC3, a long time ago and it was fine, I did prefer belt at the time. The TB03 will be used for TCS racing with a black can, therefor I hope the limited power will reduce the torque steer we use to experience.

But still debating.

redbones

Even more so, the advantage of a shaft drive using a 540type motor.

An old school debate compares shaft drives to belt drives and weighs the merits of drivetrain efficiency and throttle response against the absence of torque steer and throttle "give." For modern high power motors the debate is all but over: belt drive is better (shaft drive zealots feel free to flame on--you're all half-crocked--fun--but nuts.) But for GT3 (silver can), the arrival of the TB03 renews the argument. I look forward to next season's TCS series to see how it shakes out. It should be fun! I love the new body and have wanted to try a shaft drive car, but the TB02 was just too dated compared to the TA05. Not anymore.

So what's your guys take on the motor limit of shaft cars before you hit deminishing returns?
