Ran the car for the first time Sunday (carpet/RC Madness). The car was pushing on and off power like crazy with the kit setup. Made some changes (springs, oil, shock positions). Can someone share a setup or give me some other things to try.

The drive train has definitely loosened up a bit, still has a way to go though.

Its not a setup, but if you want to force some reaction try increasing the front kick up, it should generate at least off power steering... May make the balance horrible though!

What internal shock limiters are you guys running on each surface (dirt/carpet)?

my setup for rcmadness on my bmax4 was 45/40 with the 1.7/1.6 fr/re pistons orange front and rear springs and no droop and 17mm ride height, I used this for both the astroturf and carpet at madmess, I would imaginbe I would start with the same setup on my YZ4 when i go up there.

Thanks! That is pretty close to where I was. When the car started coming together.

Can you explain what you mean by no droop? I haven't really raced off-road in about 8 years.

Gotcha. No droop in a tc would be kinda the opposite. Spacers in the shock would take droop out if I am thinking of it right.

I know...I was shocked too that I had gotten something right.

Please explain how a motor affect FDR. My dad was a factory Suzuki riders the 70's so I grew up around racing and have myself raced and worked on motorcycles and karts and did RC for many years and I have never heard of such a thing.

As far as all the knowledge I've accrued in my 42 years on this rock, gear ratios can only be altered/affected via introducing different sized gears. The force driving them only changes how much power/speed/torque drives the transmission.

Different motors will work best at different FDR values based on the available torque and RPM.

No droop is the same as TC, it is NOT "no" limiters, its probably 4-5 limiters in the shocks? But haven't done a no droop setup in my YZ4 yet so I dont know how many exactly, also a sway bar in the rear will help loosen up the rear a bit also.
