They are 4x's more expensive but I like supporting my LHS for odds and ends like this and I assume these are better....
I also picked up a 30T and 31T pinion plus a 72T spur to go w/ the kit spur on your advice. These are very premature since I don't even have the motor yet...but like I said, going to LHS is dangerous. Plus, always good to stock up. The pinions are aluminum, was looking for steel but the price was good and I am not sure I will need steel or if it will go well with the plastic spur anyways. Tried to find some 4-40 thumb screws but no luck, not critical right now anyways.
Good choice! Boca's are great bearings. Plus they are sealed. You shouldn't have any problems with those. That's a good start on the gearing. I would start with 31/72 for spec class. If your track is a large one, you might have to move up to a 32t or higher pinion. Aluminum on the pinion is a good choice for racing. Less rotating mass equals quicker spool up all the way up through the rpm range. It's the little things that will give you the edge. I found some Associated Factory Team thumb screws on ebay. They are $7.91 with free shipping. http://www.ebay.com/itm/Associated-Factory-Team-Battery-Strap-Thumbscrews-2-ASC1787-/381820575166?hash=item58e6479dbe:g:pl4AAOSwUEVYCCE7

Thanks for the tip!

Thanks...But I think I made a silly mistake today. I just looked at the Robinson Spur gear that I got, the 72T, and the center hole (is it the bore?) is much larger than the kit 81T spur.
I assume the larger hole will not mount onto the top shaft? Will I ever see a need for the larger holed Robinson (trying to see if I should return it vs keep it)?

Don't sweat it bro. At least it's not a great big mistake. That's how we learn after all. Right? Yes, that RR gear is for the older 6-gear tranny. The Worlds re-re has a Stealth tranny with a v2 slipper clutch. The hex shape on the spur gear matches the shape of the slipper pads. That's how you can tell the difference between the two. The gear in your second link is the correct gear. Don't hesitate to ask me for part numbers before you buy or order anything. I'd be glad to guide you along the way.
Got it. Thanks for the summary. I guess I will have no use for the RR spur and will return it.
I'm usually pretty good at getting the right items, hard not to thanks to the internet and forums! But you know..when you step into a LHS...mind goes crazy and wallets stay open!

Lol, oh yeah...I hear ya. It doesn't help that I live just down the road from Hobbytown USA.

Boca makes fine bearings just like Avid does. Boca has been around longer but Avid is no newcomer. Both have different product levels available so I would not assume Bocas are any better than Avids as long as you're comparing equivalent bearing lines.
That said, while I certainly am all for supporting my LHS, $1/bearing online for a quality product is hard to pass up.

I have to say, I completely agree with you.
Just on the bearings, I am not completely sure Boca is better at all. A bit further research says that the Boca's I bought are ABEC 1's while the Avid ares 2 or 3's. I have also read that ABEC ratings aren't the end all be all for RC so who knows?
For this, there was a balance between something I needed (not really since this hobby is not a "need") versus supporting my LHS. I chose to support my LHS. That said, I did flinch when realized the bearings for $4 each. Would I do that again for bearings? Probably not...
Speaking of bearings....Got some as part of a small shipment from Tower. Not for my RC10, but for my soon-to-arrive Tamiya Mercedes-AMG GT3 #58639. Going to be busy...
The loot on the left is for the RC10. Unfortunately (or fortunately), I accidentally hit "2" for the spur and the thumb screws...(Note to self, need to stop wasting $$$) so I received some redundant parts. I am hoping that I can still use them eventually, either from wear and tear or for another project.
I think I can probably start the build soon as I still mull over the motor/esc combo.
I've done that before, lol. It's really easy to order two of something from Tower by mistake. Sometimes it will add an extra of a particular part all by itself. Not kidding. You're good on spur gears though. That's a good thing to have on hand.
I'm going to keep an eye on tower....Of course I can swear that I didn't make that mistake but who knows? I was busy figuring out how many bearings I needed...
Also notice the more economical bearing choices now? Ironically, decided to get the bearings for my Tamiya kit just go take advantage of the esave discount level I was jjjjjuuuuussssstttt short of. I swear they have those calculations down!
Seems to be the equivalent to the HW Justock 17.5. I know the HW seems generally more popular but this is interesting because it has the built-in bullet connectors which, after initial solder, makes changes motors much easier...Although I have heard not the best for conductivity. I guess the other question is, if you buy into the bullet connector from Speed passion, does it limit you? Do other motors have similar connectors?
Not sure about Speed Passion, but the SKYRC combo is plug and play from what I've read about it. If you want to step up to a hotter motor, you just plug it in.
