Well yes but I should be feeling anything but a smooth roll so to speak if i've just opened the packet surely?

Just clean them with motor spray and spin them on a sharpend pencil, if they spin up they are OK. They should spin quite a long time, if they don't spin up, they're bad.

A thin lubricating oil, such as Trinity Royal Oil #RC4051, or any other synthetic bearing oil, which is thin, and flows kinda like water.

all eight of them felt well lets just say rough
the right thing to do is return them from where you got them; if its a lhs, open the exchanged set and test the each before accepting them.

you are not to fix or atemp to fix any defective parts; it voids any warranty and/or exchange you maybe intitled to.

nobodys quality control is perfect; thats why they warranty their products.

If they are Yokomo bearings you will not have a problem in returning them, as long as you have not used them. You had to open the package in order to find out what you know and have now. Do not remove the seals though.
But if you really believe they are gritty, just return them, ceramics are expensive, and you should have good ones. I've used a couple of sets of Yokomo ceramics and have never had any problems.

to late for the wheel bearings I took the sheilds off already. But here is what happened.

After cleaning them as suggested they did indeed spin remarkably freely.

However I then put the mearest drop of oil on them and of course they slow down a little bit but still all good but it's when I put the sheilds back on I noticed the problem as first mentioned returned.

So out comes the manifying glass to have a good look (and one of the other non wheel bearings in the kit to compare).

It appears on very close inspection that in at least one spot of every wheel bearing there is no viewable gap between the (I hope this make sense) the inner edge of the sheild and the outer edge of the center roller.

Sheild off no problems though. If they were anything but the wheel bearings I'd just take the sheilds off.

Funny I could have sworn that the ESC Masami used to win the Worlds was the GM Racing SX12W in fact I am almost certain. So How could he have used the Ko Propo ESC????Just seem awfull fishy,,,,,
Just my two pennies.

I don't think Matt was saying Masami used his up-n-coming version of the KO; from what I read he was just saying that Yokomo is coming out with these versions. And even if Masami did...

Yes, I believe Masami's using GM ESC for both class at the Worlds.
For JMRCA he use KO VFS for 1:12 class. Dunno what he have used for the JMRCA 1:10 TC class

ritchie,
how are things in the nw., the more i drive this cgm the faster it gets.

got a tip for you.
testing on gear ratios; run the 48p 72t spur. ive found that its surprisingly faster on acceleration than similar geared 64p spurs. it wont work well if you run lower than 10t.
