T- when the stockers were closed-can, I spent a LOT more - either you used a stock can lathe (where you had to pull off one part of the endbell. . .pain) or you (illegally) popped the endbell off to cut the comm OR you just used a comm stick and tossed the motor after you burned it up.
I believe stock motors last much longer now that we can cut the comms regularly and, now, just skim them rather than really dig at them. . .
None of which speaks to bearings vs. bushings.

I agree that there is very little if any performance gain from bearings in stock. I also agree that we need to keep things as cheap as possible for the beginners. Stock should be a beginner class (and slower).
I can't see how 50 cents worth of bearings (2 cheap bearings) can add more than a buck to the stock motor cost. If I can get bearings that cheap then the motor companies can.
In the end, there are bigger fish to fry other than stockers with bearings.

Oh, and you can get Boca bearings at HobbyTown for $0.99 each *retail* (quantity 1), so I fail to see how adding bearings to stock motors would really change the price at all. But do they really last longer in a motor than bushings? Do you get more RPM from bearings than bushings? Why don't 19T motors come with bushings? Inquiring minds want to know...

Rick,
orion used to offer a version of the core stock with bearings I don't recall how much was the price difference though... it very well might have been around $10...

If you add 5% to cost of manufacturing, that's a lot when it trickles down through wholesale, distribution, retail, etc. It isn't just our RC Industry, it's how all manufacturing is, and if anything I would guess that the margins are fairly small compared to other industries of the same volume, so the affect would be large.
$.29 more.
Again, I wasnt looking for that level of detail. Was just trying to understand the history of it.

...plus that's a percentage based on original cost of manufacturing that carries through.
