I'm basically running Lutz setup but my turning radius is too wide/big. The car is very responsive but it doesn't turn the corners sometimes without hitting the guard on the other side.

What adjustments can me be for this? I have my toes pointing out a bit.

Default steering tie rod ends.....?

Has anybody tried the standard steering tie rod ends on there st-rr off the 777 wc? I am running proline LPR rims and tires ,so the rims will not hit or scrub at full lock .Or is there some other reason to run the st-rr steering tie rod ends.

can anyone suggest an edit to Lutz's or King's from kyosho's web site here:
http://kyoshoamerica.com/cars/index....=manualssetups

I race on smaller technical tracks that are pretty rough and traction is low, running Werks Lugs tires.

I switched from running all blue spring to blues in front and stock greens in rear. That helped a bit along with switching from 1.1 to 1.0 springs.

Currently diffs are setup 7/14/3. Shocks are one in on the bottom from the outside position for front and rear. They're one in from the outer on the upper mount for the top shock positions.

Running 700 oils in the front shocks and 650 rear.

There's a double that's not too long but a bit tall for a regular jump that immediately turns into a single. But I have trouble landing it sometimes as it like to go onto it'd lid, seems unstable landing. I have no trouble making the bigger jumps or longer ones, just this one.

Tracks not too big so any other changes to make turning easier would be a great help.

vthondaboi, Are you still running the rear blue springs on the front ? Get the 1.6 8 turn blues .Lighter fluids on a track with less traction works good for me,also will turn better on the ruff areas .700 or 800 kyosho oil in the rear shocks with blues springs.Tire selection is very important .Im using the lpr holeshots and crimefighters depending on the conditions .these made a big difference in turning ,and acceleration for me.

Just got a STRR and am looking for advice on what is the best motor and pipe combo available for it.

I am looking at the GRP .28 Tuned motor and the EFRA 2053 pipe but I am open to all suggestions.

Thanks,

If your smooth on the trigger, I would take a look at the O.S XZ .28 with an O.S 2050 or 2060. Great power combination, but some like me, need a very smooth finger to handle the unbelievable power.
