Default Diff v spool v one way

So with running 17.5 and 13.5 now, are youguys finding one ways and riffs to be quicker than spools? Just wondering if the one way and diff is faster in the corners than the spool with the slower motors. This is assuming running no boost or anything to make a stock motor run like a mod motor.

It really depends on the track. If you can do a fast lap without braking, one-way could be an option, but if you need to brake, one-way is a no-go.

I find one-ways to be quite difficult to race with, because of the sudden change of cornering-ability. The spool is much more "consistent", but it does offer less steering (but I've more than enough - I even turned down my dual rate).

But I don't know if you can use a one-way in the T3'11, as the belts are flipped, flipping the one-way also.

One ways are a good option for stock classes on long flowing tracks. Diffs are good for foam tire tc but aren't fast enough to work in rubber tire (in the front) By the time you get them tight enough to work they are usually too tight and don't last long, especially with Xray diffs. A spool is definitely the best way to go, it will take some getting used to if you've never drove a solid axle front but once you get the timing down you will always be faster with a solid axle in the front.

No. That is just one diff.

Correct, you can't use the existing 1-way flipped. On the Xray forum Martin said that the new multidiff would be out soon for the flipped configuration

What about this, I'm not sure exactly what I'm looking at, could be a modded NT1 diff

Default Building a smooth xray diff

Never had any problems building smooth schumacher diffs. Just re-built the diff on my T3, used a new thrust bearing, new spring plates, re-surfaced the diff plates (1200grit wet and dry). Diff still feels notchy. Using silicon nitride diff balls and its the only thing I havent changed, anyone had any experience of these getting flat spots on them?

That's not an "Xray" part, manufacturer says "Other". I think someone local to RC Market is making those for them for the T2/T3. I think it is a modded NT1 diff, I've seen RC Market post pics of them before on different threads. It would be nice if Xray would come out with their own version. Hopefully it's in the works.

Hopefully you folks can help me, aside from some carbon fiber pieces, and the orange anodize are there any other major differences between the T3-2011 and the T3R? I'd love the 2011 but the $225 price difference nearly gets me 2 ROAR approved batteries. I will be club racing on asphalt and carpet on spec tires. I know the asphalt tends to be harder on a car than carpet and I figured that should I break anything I'd upgrade to the 2011 spec parts. Budget is a consideration for me and as someone returning from 7 years of "retirement" would I honestly be able to realize the differences in the 2 cars? Thanks in advance.

Chris.

Aside from what you mentioned, the largest difference is going to be the steering system. The 2011 uses a dual post rack while the T3R uses a single post system. Will getting a T3 2011 make you a better racer at this point - doubt it. Get the car that your budget affords an have fun at the track.
