Large outdoor asphalt track. Rubber tires. 12 Turn motor limit.
Car lacks steering througout the turn with my current setup so I'm looking for some ideas...
The first 200 posts of this thread should containg a good setup for PB. You can also go to TSN and download some of the very early setups for the T1.
I'm using PB myself. I run with a one way. Very good steering plus tank-like durability. No worry about losing kingpins. People say I'll get even better response with the C-Hub suspension, but I'll wait until Evaa here will convert his first.
Servo saver : use the inner two holes. The resulting ackerman angle contributes greatly to steering.
Zero Kickup :
Eccentric upper arm position : Front holders upper hole / Rear Holder middle hole position.
One way diff:
Caster clip: 3mm front of upper arm
Caster : -1* (front leans towards the chassis)
UpperShock position : middle hole on the original T1 front shock tower.
Lower Shock position : outer hole on the PB arm.
When I first acquired my T1 with front ball diff, I also felt lack of steering. So I sold it and the buyer hopped it up, went broke and sold it back to me with one ways, 1.77 pulleys, Ti screws and Solid center shaft.
The box setup with 3* kickup results to very good initial steering but lacks mid and exit steering. The reactive caster actually puts the caster closer to vertical on compression, affecting camber and contact patch, resulting to loss of traction. The pushes on mid corner and I have to cut back on throttle.
I reversed the setup such that on midcorner, the caster actually increases (leans towards the rear of the car) upon compression. This induces more negative camber and better contact patch on mid and exit. The front is sprung soft to allow the caster to react. I use the orange short spings.
