Quick Q - I race stock rubber on indoor carpet - and I just now realized that the 007 I bought is more then likely the US spec foam kit. (Awaiting a reply to find out for sure)

Is this kit going to be a disadvantage over running the rubber spec kit since I will be racing stock rubber on carpet?

In low bite situations the EU kit wold be better suited. But for most carpet tracks in the US and especially Scotty's the US spec should be ok. If you find it doesnt have enough traction then you could get the chassis from an EU and a mulitdiff and have the best of both worlds.

Knowing this I plan on the multi-diff as (I'm new to Xray so forgive the ignorance) I believe it also functions as a one-way. Loved my MSX with a one way versus the diff - so I'm sure this car will more then likely be the same.

Thanks for the quick reply. I guess having both wouldn't be all that bad.

Yes the multidiff is a oneway, spool and oneway spool in one. Its a little on the heavy side but you dont have to worry about it breaking!!

Measure the chassis thickness. The EU is 2.5mm thick and the US is 3.5. I have been running the EU on low to med bite carpet and it's been a dream to drive.

lol - any lighter one way options - or is the multi-diff what everyone runs?

if the multidiff is on the heavy side is there a light weight spool for the car that's as durable as the multidiff? Thanks again for the info on the car. I love this thing.

That's virtually a spool? Or am I missing something?

with the delrin housing it is a full on spool. Just for fun i think i am going to go weigh it (building my EU spec kit now, and have the US spec ready for testing at stocton when i get time)

Weights are as follows, 0.3 oz for one way housing 305112. Multidiff, 0.8 oz. T2007 spec diff 0.7oz, FT05 Diff(hollow outdrives), 0.6 oz for the assembly. I would imagine the delrin housing would bring it down a tenth or maybe two. Idea, just run the diff from the ft05 or 04 if you have it and crank it down. why? its free and weighs about the same. Don't hit anything, and you will be fine lol

FYI,

On my *food* scale here are the optional axle weights:

19g - New composite ball diff
19g - New 007 alum ball diff (solid outdrives)
18g - Recently retired T1/T2 alum ball diff (cutout outdrives)
18g - Multidiff (locked one-way and spool config)
17g - Multidiff (one-way config)
12g - Delrin spool set (w/steel outdrives & pin)

The multidiff in one-way config is actually lighter than the alum ball diffs.

One last thing of note is that the multidiff is a good bit lighter than the ball diffs as you move out from the center of the axle.

I have to laugh... and this means absolutely no harm to anyone that chimed in and posted info up on this thread in the last couple posts.

I asked about a lighter one way - and got all sorts of info on spools.
