Yes, I am running on a semi smooth parking lot track with low to medium traction. I am using the kingzhead bellcrank with a 9, but it doesnt seem to hit anything. And there doesnt seem to be any binding on the servo saver.

I am using a futaba low profile servo. The thing that I notice is that the servo seems to not have enough throw when turned to the right. I will go back and look at the servo horn directions in the manual. That may be my issue.

Thanks,
Chris

I didn't think so either until I put the car on a setup station and had about 4dg difference right to left in max throw angle. You should be able to get 25dg.

While we are talking about it, how many degrees of steering are you guys getting? I get about 16, but rarely race with full throw. I've found that in ideal conditions, I'm using about 12-13 degrees of steering.

Could have sworn last I checked mine was getting 24 deg or so, can't check that though cause I had borrowed a setup station, still don't own one.

I actually use a great deal of my steering now, could be because I also run a front gear diff, meaning you can really use all it.

a few things that give more steering/steering lock...
  • spec-r yokomo ecs shafts (must use xray c-hubs though)
  • dremel the stop from the standard steering arm
  • dremel a notch into the steering arm where it hits
  • use ackerman insert 9..
  • try a harder spring on the back of the car
  • try a higher roll centre on the back of the car.

test these combinations and you'll be able to get enough lock and also enough steering on the track.

I found it was just in terms of the amount the car rolls, could run a lower RC on the narrow chassis without as much scrub compared to the moderate lipo chassis

Hey All,

Just curious...
When you remove the roll bars do you make any other changes? ie stiffer springs?

the only change that i made was going from 350 wt oil to 400wt oil in the front schocks & it seems more consistant without the bars,thats running at castle hill track in sydney & illawarra which has more grip than castle hill

Bars are for wimps
I've never run bars on my photon -- not even 100% sure how to put them together. I think the car as has such good forward bite that you can run setups that would drive other cars to simply do donuts as at least my photon is sprung with hard springs as compared to XRay or Tamiya you typically find.

when i first got the photon i built the car as per instructions with bars,(had run bars on previous xrays & tamiya's) as was everyone else using bars, but when i removed them i found that the car was sooooo much better & havnt used them since.along with some other changes iv'e found this car by far the easiest & most consistant car that iv'e ever had & it seems to work well with only minor changes from track to track so TWF ditch the bars i think you will be pleasantly surprised

explain to me why longer rear camber links gave me much better rear traction.

Cyrul, if you are reading this, make some more of those narrow chassis and sell them through cefxspeedshop. I'm sure I'm not the only one who wants one. I actually want two of them.
He is not reading this thread
