RB5 Gearing and Maintenance Questions

[Kaipaki348]

Hi - great site!!

Just got an RB5, new to rc and want to know about the gearing and set-up. Am running a LRP Eraser 9.5 turn motor, 20t pinion with LRP Sphere Comp TC ESC. The spur is stock (78 I think). Battery is e-power 4500 NiMh run in forward position. I typically run on a loose 1/8th track and find the set-up sheets posted on this site very helpful.

Have a few questions (as am a novice) and would really appreciate any help:
- How do you work out the gear ratios, what do they mean?
- What is the best pinion/spur to run?
- What are the shock spring options (what are the different colours and what do they mean etc)?
- What maintenance do I need to do on the motor?
- How tight should I run the diff, and how noisy should it be?
- How tight should I run the slipper?

Thanks!
