Thanks to rc_square24. The 3mm shims behind the bevel gear is what I needed to get them shimmed.

Time to see if it can handle a bit more power in the modified class!

Sure! Nearly all hop ups are now out and available. I bet next year...and I think it will contain a good range of hop ups like TA07R.

The newly announced hop ups arrived today.

#54905 Aluminium rear damper stay mount
#54923 Adjustabe ackermann set




Rear damper stay mount is more rigid than plastic part. But I'm missing same for front.


Ackermann steering set. I started with insert \"B". "A" is kit setting, "C" the most aggressive initial steering response. Surprisingly the new parts have better tolerances than the old aluminium steering set. Only shims between plastic part and bearings needed. In the steering bridge i used no shims.


Ackerman steering set with the inserts.


With insert \"B" now full steering angle available without touching/bending the main frame. Seems Tamiya heard the complaints.
After mounting the steering set the linkages have to be adjusted.

I ran my converted TB05 to EXO-SIXv2 car at the Protoform cup. It's such a joy to drive! Finally had a chance to upload the A1 race. Some traffic snafus hurt my qualifying (only 6th) but the car was so smooth it allowed me to work my way up to 2nd here;

Seems, something with the bearings is wrong. Maybe two countersunk screws in the bridge would help to center the bearings (kit are flatscrews).

Main problem with basically all Tamiya steering units is, that technically they are using the wrong bearings (ball bearings have slop with longitudinal forces). In a steering unit something like a thrust bearing or cone bearing would be better solution.
I agree that the slop is terrible and cased by the bearings. But, a 5MM shim under the bearing between the bearing and the steering arm and same for the bridge resulted in both smooth operation and slop-free build. I learned this while playing with the M-08 and it worked on the TB-05 as well. Give it a try. I think I used a 5mm x .1 mm shims in each bearing hole.

The new ackermann steering unit doesn't need much shimming. The ackermann steering bridge has smaller bearings which have less slop.
