The first two upgrades I made were to replace the plastic spool cups and add ECS's/DCJ's. For the price of one lonely XRAY ECS driveshaft, you can get a pair of Tamiya DCJs.

The XRAY ECS's have had a few weaknesses over the years particularly when running mod. At first the 1.5mm pins broke. Then when they upgraded them to 2.0mm pins, then some casings started breaking. Personally, I have never seen or heard any issues with the Tamiya DCJ's.

The Smokem spool cups are also cheaper than the XRAY items. They don't need blades (that get ripped up pretty quickly in a spool) and are long lasting.

So basically you get a smooth, bullet-proof front drive assembly for a fraction of the price. What's there not to like?

Thanks for the heads up.

I think the main advantage is interchangeability with other manufacturers' parts (you can use Yokomo, Corally or Schumacher diffs and I bet Associated too) plus you have a selection of three different dogbone lengths to choose from.

Yokomo have similar DCJ offerings but to my knowledge only one length available (I think it's equivalent to the Tamiya 44mm dogbone from memory).

That depends on the electronics and battery you choose to run.

One note on the smokem cups, install your bearing on the diff before building it. The OD of the outdrives is about 10.5mm so will not fit in the 10mm bearing hole.

Edit - Actually scratch that. It will not work at all. You either need to use a 5x10x3 bearing or wait for them to fix this issue. The stock bearing does not sit flush with the face on the diff, there is about a .5mm difference. So the gear pin in the shaft does not go in.

Doh! Hopefully they resolve it quickly and replace all the ones sent out.

A 5x10x3 on both sides would probably let the whole diff move around a lot. I doubt it would work.

I was just coming here to say the exact same thing. The outdrive doesn't clear the bearing opening so you have to put them on before assembly, and they can't sit all the way inside the gear diff because the bearing doesn't let them sit flush. Only way to use them is to remove the shims from the gear diff. I've got two sets that really aren't usable because of it.

You also have to put the screws in before the bearing and then try to tighten them down with the plastic cam in the way.

Well, damn. I haven't even opened my set, but this is disappointing.

Smokem Racing just e-mailed me and offered a full refund for the cups. That is the kind of response the rest of the industry can learn from. Very well handled, and I hope they can fix the fitment issues and come up with a Version 2 of the cups.

And guys, when you get bored with all that screwing around, use the refund to get some Tamiya TB04 aluminium otdrives which you need to re-drill and cut. Easy and can be done with home tools. The shorter TB04 outdrive can be drilled in the Tamiya hole (will need one .5 extra shim), the other one needs a new hole. Or get two sets of outdrives and use the short one from both sets. Job done, plus you get a really good quality outdrive!

You call buying Smokem Racing products "screwing around" and describe drilling and cutting Tamiya ones as the holy grail? Uhm... no thanks
