That sort of describes the set up I have now. I will be trying different tires this Sunday and see if I still have traction roll.

Have you tried Ca ing the side wall of the front tires?

CA the inside wall of rubber??

I'm trying the old set and new set to see if it's the tires. (I think it is.)

AreCee, he said side wall not inside wall...

Gluing the outside wall of the front tires will help to reduce sidewall roll-under.
What happens on high bite tracks like seasoned carpet is that when the car approaches mid corner, the car has scrubbed off enough speed that the front tires will get more bite thus causing the sidewalls to roll inward with respect to the rim and will cause the rim to act like a plow. No more understeer and woops, the inertia of the car at the inside of the turn wants to pass the outside. Your problem is probably more tire related than setup.

Like I said in an earlier reply, tuning down the dual rate on your radio can also help. If the front tires are at a high angle when turning, understeer will be induced until the car slows down and then the car will experience massive oversteer causing the car to virtually stop via the leading front tire. Over she goes...

A stiffer tire with a stiffer insert will help but obviously, if too stiff, you'll understeer all over the place.

I hope I'm helping here.

Perhaps some of the other guys can back me up on this?

By the way, you should have many sets of tires to try when experimenting on an unfamiliar track surface. Perhaps at least 3, soft, medium, and firm so that you can have something to compare to. Try to avoid using old tires all together since you will not have a direct comparison to different compounds. The sidewalls go through a lot of abuse and become too compliant thus causing them to roll under easier than normal.

Yo dog i got your back, some were gluing the sidewalls at iic this past year. Traction got pretty high and we were running the jaco blues which are a soft tire. And that seems to be the tire of choice for handouts so when racing on a high bite track, it might come down to that.

Thanks Weezy,
almost sounds like we know what were talkin about.

I was at work when I misread the post thinking he said the inside side wall, not the inside of the tire. Yes I do know about CAing the tire but what I can't figure out was the dramatic change from one week to the next in traction with the same set up on the same track.

Oh well, I just needed an excuse to get new tires.

Hi all, just wondering how do you connecting the sensor cable on the E4RS? I have a SP 17.5T BL motor and a 180mm cable. I managed to route the cable from my Sphere over the top deck then down through the gap between the motor and the top deck and come out at bottom gap between the belt-tensioner post and the motor. But I do not think I leave myself enough room to move the motor at all. I am running 94/46 but I do not have the gears to try out as I cant find them in Melbourne but some is on order.

Do you have other method of routing the sensor cable?

Also for servo mount, except xray ones, is there any other options?

Hey.

I cant help you out with the sensor cable as i havnt used one in the E4 yet.

with the servo mounts i used the ones of my TRF 415 and they fit fine, also the Hot Bodies Cyclone servo mounts fit fine as well.

HAHA we can pretend right

you can also use the asc tc5 servo mounts

Harder compound tires on the front cured my traction roll issues on high bite carpet.

Here is a pic of my E4, its ready all ready to race now.

I pull the sensor cable right through the belt, loop it over the top motor pod brace and tie wrap it to one of the motor wires.

cool thanks for the tips guys
