Running too much radius with stock bone will result in this:


Also you said your knuckle hit the c arm when you turn. I just check mine and the servo stop before that so, something wrong with your C arm maybe. How are your turnbuckle for the camber in the front? Are they straight or the outter cup (c arm ) are more toward the front of the car? Try to switch the c arm around.

Group B & Driftwoof,

Thanks for the pictures! Now I understand what is going on. As stated going to 44mm CV drives will help with radius. Sorry for my ignorance as I did not assemble my TB out of the kit with the dog bones.

Either go to 44mm CV drives or take a dremel and grind the axlecup down. (I prefer the CV drives.) And with a spool make sure to use the steel axle drives.

Jimmy

That's great guys, thanks for your help.

Just to clarify. These are the parts I need right?

https://www.tamiyausa.com/product/it...oduct-id=54076
https://www.tamiyausa.com/product/it...oduct-id=54078
https://www.tamiyausa.com/product/it...oduct-id=53500

And 46mm length in the back?

Keep in mind I have a Tamiya Front One Way and Tamiya Direct Coupling in the rear.
Will it make a difference? Still 44mm? Thanks again.

I got 46 in the rear with the 1XA-1D mount (stock tb-03) but check before , I think the tb-03D dont have the same mount. I got the 46 in the rear because I already have them, if you have to get both get the 44 in rear too maybe in allu too.

I ordered them already crap. 42mm? So will I need the 46mm instead?

I just measured my stock TB-03D dogbones. They are 50mm long. Should I be worried that this isn't over?

Did you buy the TB-03D upgrade pack?

EDIT: I need 42mm not 44mm. It's on my manuel. I need 42 for use with a direct coupling/front one way.

I forgot to add, I have the same wear on my dogbones. It;s somewhat deep. Is this a design flaw or put together slighty off?

I ordered 42mm Swing Shafts for my TB-03D. It says in the manuel if you have a Front One Way or Direct Coupling to use 42mm swing shafts.

I drift so I need these because I need all the steering I can get out of it. I need the knuckle stopper to hit the C hub to max out my steering.

your knuckle are not supose to hit the c arm . mine at max (by hand) are 2 mm away, and more than that the steering shaft will hit the driveshaft. I am using the blue allu horn saver and tamiya hi-torque. Did you try to switch the c arm around? Maybe the tb03D have a different c arm caster... When I drift I use a spoll in the rear and I drift with throttle more than steering, and I use the dual rate are 60%.

Mine are also 2mm away. I got the swing shaft to see if I can max out my steering because the steering shaft hits the drive shaft. With swing shafts I can pull a tighter turning radius... I am hoping. I want the knuckle to hit the C arm to max out my steering. 2mm is important to me to gain. I drift in narrow tight tracks so I need all the steering I can get.

I am really hoping the swing shafts work and give me the full turning radius. The stopper is there for a reason and I want to use it maxed out.

We'll see. Thanks for your help. This is the most relaible place to get help for my TB-03D.

the universal will get ride of the vibration you got from dogbone for sure and maybe give you a little more steering but..

Dont forget the part was original build for the 416 and the steering are not the same.
What will limit the steering radius is the driveshaft/steering clearance and the pushrod for the IFS setup.

using a longer servo arm are the only way I see to get more steering radius..
My advice is max the clearance of the driveshaft and built a setup from there , weight transfer ect will help to drift better in tight track.

I ordered a Tamiya alluminum servo arm. I don't think it's longer though.

Maybe I'll be fine. Once I get the steering figured out. It's smooth sailing hopefully.

What's a good longer servo arm if not?
