XRAY - Model racing cars

Hello,

I m going to buy ecs drive shaft and I would to know if it's really recommended to use them with a spool?

I would to know too if there are conditions where i do not use them on my car?

Thanks,

When I use a spool in front I always use the optional ECS driveshafts to get rid of chatter. With a gear diff in front you don't have this effect as much so regular driveshafts will work equally well. But sometimes, the chatter effect when the driveshaft is "locked" up on full lock and on-power will give more mid corner steering, especially with a front diff. It is hard to explain but it will make the car "snap" in the middle of the corner and thus rotate better. So even if the ECS will get rid of the chatter noise, it will not necessarily give more steering. So when I use the diff in front I prefer to use standard driveshafts.
