Love to have both and more, but finances don't allow it. Oh well . . .

My understanding is the carbon reinforced tub is the only hop up tub planned for now.

i'm considering getting the delrin out drive. does anybody have any opinion on it?

Another option i'm thinking of getting is the aluninum diff gear. it's more durable but wouldn't it affect acceleration?

i'd aprreciate any comment...

The aluminum diff gears will slow down acceleration due to more retating weight, but if you are running a wide open track with lots of sweepers that you don't have to slow down for most of the track they could actually help the car maintain a higher rate of speed thru the coarse..... unfortunately I don't believe anyone has ever tested this theory.

But then agian if you get delrrin/composite outdrives you may end up with a diff that is close to the same weight as stock.....

Default TA04 Pro

What do you guys thing of the TA04 Pro? How does the HANDLNG compare to the TA04R (when equipped with same sway bars, springs, etc)? I know that the TA04R is a better deal, but I'm just wondering it the TA04 Pro is a good handling car compared to it.

Many says O4 Pro was one of easiest to drive ( box stock ) when it came out. Version R was better handling, says those people who bought, maybe because of it's tub chassis but all agree it's the best deal ... I have the Pro with Saddle Chassis...

Default Anyone have this TA04 part for sale?

Hi. Does anybody have the chassis posts from the TA04 Pro that they could sell to me? I'm getting a TA04R, and i will upgrade to the saddle chassis, so I will need the posts. Thanks, it's a huge favor.

For the mean time, what could substitute the post tempararily? Would using a very long falt head screw (placing long spacer in the middle) and connect it with a nut? How about the HPI Aluminum Posts (that come with RS4 Sport/Pro/Rally?)

HUGE thanks (I would have a pic of the HPI Aluminum Posts, but HPIRacing.com is down of course!)

The Hpi posts should work, if they are two short then use washers and shim them to be the proper height, if they are too long they use a dremel to cut them to the right height.

If you have to cut the flared portion completely off they I would cut them short enough to add a washer on that side to avoid breaking the graphite plate it mounts too.

If the posts are within a few millimeters then find someone with a bench grinder and remove slight amounts of material from the top and bottom to make the proper lenght..

Hope this helps.

Does anybody knows how much caster angle does the Racing C hub have?

I believe I read on some site that it has 6 degrees of castor. The stock one which comes on the 04 pro or s editions have 10 degrees of castor.

No idea, haven't tried the 10 degree hub before. But from some setup tips websites they mentioned that less castor increases the steering. Whereas more castor is meant for stability at high speeds; suitable for larger high speed tracks.

Default Castor Angles

Just went around the tamiya websites; please correct me if I am wrong:

TA04R (Translated from Jap site): Front/Rear 6/2

TRF414M: Front/Rear 4/? (The .nl site mentions it at 4.8degrees todal)

TA04 Pro: Front/Rear 10/2

TA04 S: Front/Rear 10/2

Could explain why my turning is better compared to my friend's TA04S but there are too many variables involved (motor, options, weight, servo etc.)

Default Re: Castor Angles

... why? beause when steering, the more caster you have, the more you turn the front wheels to their sides - reducing contact patch between rubber and track - resulting in less steering. caster should work together with camber setting.
