Thank you once again, Peter~!!! You are such a great help:D
My car now goes wherever I want it to go, I can drive it comfortably!! Here is what I did, one after one.
1. Play with the weight balance for a while. I have my car balanced at home with balance tools - 10g to the front of the battery and 40g to the back of the battery, it was perfect on the balancing tool. But on the track it can't go straight and I have larger right turns. So I take some of the g off, now, 10g to the front and 20g to the back. It goes straight and left and right turn is pretty much the same (setting in radio is the same), but the car is not balanced on the balancing tools. I assume it only measure the car is in balance in still motion, but can't reflect reality. i.e. motor spinning and drive belt spinning, etc.
2. Changed quick saver position from No.2 to No.4. It feels totally different in cornering, more steering now at corner entry and smooth in mid corner and corner exit, but still not enough, I think there are still room to be improved.
3. Reduced front track width to 1.15mm. Yes, much more steering, but a bit nervous, so I change it to 1.3mm and it feels stable yet more steering. Hence, I have to look elsewhere to increase steering.
4. Reduced wheel base, less stable.
5. Fine tuned ackermann angle on the steer block, I moved it forward. I don't like it, so I moved it back to the original place.
The car was good enough to run for the night. So that's about it for lastnight. Next weekend, I will play around more with the ackermann (ie. No3. hole and forward steer block hole) chasis flex, and roll center links.
Hopefully, I can find myself a comfortable setting and start setup my 1:12 soon, to train my fingers.
