Actually from what he says, it sounds like he's keeping the pin flat. In that case, your lowering the front roll centre, and hence more grip.
Also, if you just lower the front pin mount (so the front of the arm is lower than the rear) you get pro-dive, not anti (BTW, Kick-up IS anti-dive). This gives more initial steering (something I use with good effect when running a spool in my 415) on corner entry, but also reduces the castor angle. Of course the roll centre also changes....
I'm not sure about the link too... I've always found a shorter link to give more grip through the turns...

Yep ...I'm running this on mine and that is the effect it has.

You can get 2.4mm from HPI

I'll have a look ... I worked out that 2.4 is almost 3/32 ... 2.3812.... I wonder if these balls are 2.4 I am going to check them on a micrometer tonight before I purchase as all the places in UK have either 2.5 or 3/32 ...

I got my diff balls from Acer, they have ceramic, carbide and HCCA (ultralite) and they offer all popular sizes including 2.4mm.

I run 2.4mm Ceramic balls, the diff is smoooooooth... until you hold one wheel and the spur. Then its sticky. I think the diff rings are actually sliding on the diff halves. Next time I take the diff apart I will try and resolve it. It has been suggested that I glue the rings to the halves, but I am reluctant to do that.

I have yet to find another 05 with ceramics to find out for sure if thats what causes it. Every one else I know running the car is using the kit balls and there diffs work fine (tho not as smooooth +)

Your right about 3/32 - but check out Microtech - they have 2.4mm ceramic balls in sets of 12 for the Pro4.
They will do

Hi,

I still have the same problem as you do with the diffs. I am going to pin a diff (like you do in 1/12th scale) to see if it helps. I also went to 3/32 balls and made the differance up in the rings (ground them down) this seemed to help a little.

are you going to the Vegas race???

Thanks

On MyTSN, their was an article about polishing the diff rings for Serpent cars. Really helps make the ceramic balls glide. This is what I did to resolve the stickiness. Even smoother now.

Tim..

As 3/32 is smaller than 2.4mm ... grinding down the rings seems the wrong thing to do... but I could be wrong...

I may just go back to carbide balls... we'll see, the diff feels great and I haven't had any issues (that I can tell)

No Vegas for me...

Hi,

I might have used a size larger than 3/32 as they came from my son's shop . they were marked 3/32nd and were larger than 3mm I only took a light pass with a blanchard grinder. I will let you know how the pinned diff works out.

sorry you can't make it to Vegas.

hopefully we'll see you at Cleveland.

Thanks
