you usually want around 2.7-3.0 FDR I only run 21.5 and usually run around 93/33 spur/pinion
I prefer 64p , finer FDR tuning. I only run the xenon 64p spurs, they give you 16 balls for a great tunable diff

the laydown servo is easier to fit under bodies and less slop in the steering, it feels more consistent to me. You have to cut the carbon arm mount plate to do this the best way
Thank you very much, your answers have helped a lot!

Just one more question. When using the laydown... Does the height matter? My point is that depending on the height of the servo the Ackerman and/or bump steering might vary a lot. Do I need to check something to make sure I have the right Ackerman and bump steering?

Thank you!
