I was ondering if anyone has tried T2 hubs on the 415? Anyways, ill see what the oil change in the shocks will do, and go from there. Thanks guys
Which way the arms are oriented does not affect the way the RC is calculated. You have to find the point where the lines continuing the arms and the upper link crosses each other. Then from that point, you draw a line that goes right to where the opposite tyre is in contact with the ground. Do that for both sides, and where those lines crosses is where your RC lies.

To answer your question regarding oils and springs, given the same layout and surface, going from a perfect oil/springs setup for the flat track, you'd go down in both oil and springs for the same bumpy track.

see photos below...the braces and posts were from the original 415. I cut them to fit the MSX chassis. If you try this, make sure you have a good assortment of shims. The plates must be shims on to the posts in order to avoid tweaking. You'll see if you try it.

Ever since i got my MSX i have used a centre pulley with the standard one-way. I am wondering what effects i would notice if i used the one-way with the centre one-way?

Cheers, Charles

The car will be much smoother, and easier to drive.
Good example of this was Richmond Rogers at the last carpet wars meeting. He was running the car like you were, put it on TQ, but admitted himself that it was only really by being consistent that he managed it. Had a little look over his setup, and suggested trying the dual 1-ways.... went onto easily win the meeting over the two finals (won both).
He came back and said the car was just much smoother and easier to drive, whilst still being as quick.

The reason, I believe, is to do with not having the front belt rotating off power, letting the front one-ways do there job much more effectively.

Double one-ways is something that confuses me.

As one-ways increase turn-in, wouldn't running 2 (diff + layshaft) make the car turn-in even more?

Can someone explain why having the front belt/diff rotating off power makes a difference to the car's steering/handling?

I know it means more rotating mass but how does that actually effect the car?

I wouldn'r pretend to say that I know exactly why, but it is deffiently something involving the non-rotation of the front belt.
I think the best way to explain it is like this....
With a front belt rotating off power, you have more momentum/inertia in the drive system, this in effect acts to slow the car more rapidly... which can cause problems when running a 1-way axle. You are also relying on the bearings in the front one-way to provide all the free-roll, whilst also working against a rotating pulley...
With dual one-ways, a direct link with the centre layshaft is removed, and the whole of the belt/front pulley no longer rotates off-power. a) it means the front one-way bearings will work more effectively, as they are no longer working against the pulley and b) aids corner speed as there is less rotating mass in the drivetrain.

Honestly, your best bet is to try it back to back. Personally I always use dual-1ways.
