Default BD corner speed

Can anyone help with this?

My BD turns in well and remains consistent through mid and corner exit however, it doesn't carry as much speed through the corner as my 007. The Xray is still 1 to 2 tenths quicker than the BD. The Yoki is so much easier to drive but how the frick do I get the corner speed up!

Using a typical carpet/foam setup with front diff, new yoki orange springs and rayspeed 2 hole pistons up front and yellow springs with rayspeed 3 hole pistons in the rear, 30wt oil all around, 2 degree rear toe and so on.

It would be cool if anyone has any suggestions.

Hi,

with foam tires 30wt and the orange springs are too soft. Go with harder Xray springs and atleast a 50wt oil with less holes in the pistons.

Cheers
Chris

Went with 45wt all around, xray 30lb front and 24lb rear springs and the car improved a lot. Tried the front one way, even more corner speed but lost some consistency so went back to front diff - good compromise. It's on pace with the 007 now but more consistent....for me.

The surprise is, that I didn't lose the forgiving feel that the car had when it was softer! Thanks so much for the help!!

It does look like that the HPI design, used in both the PRO4 and currently on the Cyclone, is prefared for rubber outdoor asphalt.

It was used by Masami at the Worlds in Italy, and it was also used by the Tamiya drivers on their 415 at the worlds 2004 in Florida up to the time they came up with a similar design of their own.

Here is Masami's car from the Worlds 2006 in Italy, using both front and rear HPI suspesnion parts.

I guess I can assume form the pics of masami's car that the chassis is definitely not stock. Hmm I wonder what the stiffness is. I can tell because of the fact that it doesn't have the cell holders.

no cell holders? i can pretty much see them. just that it appears to be hidden due to the black mesh placemat material used to cover the table.

I just noticed that rear shock tower is different from both the Masami edition and the standard one. It looks like the Masami one but with less holes.
