Actually tinyrc.com has a sister site: www.miniz-racer.com

they have a squat can with ball bearing and the neo magnets....HUGE difference!

An the have the pn-racing carbon brushes as well!

is there any way to rigging some bearings to the stock can. i have 4 extra 2x6mm bearing. i woudl love to put them to use

binaryterror · #33 03-28-2003, 10:03 PM

from what i seen...it might be possible if you can dig out the stock CRAPPY bushing...it is night and day difference on the BB can and the busing can.

Definately work $9.90 from mini-zracer.com

Already getting the neo mags, and thanks for the info and links 3series takumi, looks like it's not too difficult to install the neo mags. Also going to probably try getting the bb can. Couple of other questions though. Is there any other way to mod the motor? I haven't taken one of these apart but I was wondering if there's some way you could drop in say, one of the PN racing armatures into this thing. Of course the motor shafts are quite different... I suppose I'll see if it's even possible when I open up the can myself. Would be nice to somehow use the PN-S03 motor and still have 4wd.

I suppose if I have no choice, I could always try one of those mods that the other guys have done to just have the gearshaft separate so I can try dropping in whatever insane motor catches my fancy.

Hmmmm... I can see how these little things can quickly become an obsession that eat up lots of time and cash. Aaaargh! darn the Bit Char-G for reacquainting me with the R/C world!

i have been lookin for a way to mod the motor too. i would love to put the s03 in the X. the only difference i can see it is that long rod. if there is a way of yankin that rod off then the moding can begin. i plan on opening my motor again and i will take pictures so maybe someone else can help. i am sure there has to be a way to pull the rod off or add a rod to the other motors. (bluemax_1) you said somethin about a separate shaft, what thread is that in. i would like to see that.

3series takumi, that was exactly what I was thinking about when considering a PN-S03 motor mod, but since I haven't pulled the mini-x motor can apart, I'm not sure if it's even feasible to somehow keep the armature but change the rod/motor shaft.

As for the thread, it's under 'shaft mod' the person who did it even has some pics so you can see what it looks like. Would allow you to use a 180 motor, or as large a motor as you're crazy enough to try to fit

How about an all-motor 540 mini-x!

Wouldn't even have place for the batteries almost

Of course though, if you take the time to do a mod like that, you could probably just go ahead and use one of NML's 30+mph mini-z motors. Should think that would be fast enough.

Sure would be nice to figure out how to just change the rod in the motors though. Would make for some nice mod possibilities, and still keep it LOOKING stock.

The "rod" on the motors...is just a long armature shaft. You can't really pull it out...now if you knew a really good welder/machinist you could add more shaft to the small 130 motors.

Alternatively, the shaft mod is a decent idea...however...my mini-x already destroys quite a few mild mod mRS4's so i think a crazy 130 is outta the question for me..

You guys could also upgrade the stock with the magnets, the BB cans, and then hand wind the motor (it is currently 70T).

bluemax_1 · #39 03-30-2003, 06:14 AM

Oh well, so much or the idea of changing the shaft, although instead of welding a longer shaft attachment, I know there are some... hmmm... can't even remember what they're called but they're like sleeves that can be screwed onto the end of a shaft of specific diameter, which would allow you to add another length of same diameter shaft to the end. Basically allowing you to extend the shaft. Not sure how they'ld hold up under the continual torque placed on them by the motor though.

So binaryterror, what mods are you running on your mini-x and when you talk about destroying mild modded mRS4's do you mean in handling or in top speed as well? Any idea how fast your mini-x is capable of going?

I'm thinking I'd probably just go as far as getting neo mags, a bb can, adding the extra fets and maybe 8-cells with the diffs to take advantage of the extra torque as far as speed and power mods go, and then concentrate on handling mods.

So does anyone else find that their wheels still have play/wobble after installing the mini-x bearing set? Or are mine not quite up to spec?

binaryterror · #40 03-30-2003, 08:02 AM

Bluemax...yes they do make collars that can be used to extend shafts...if you get some high quality ones you might be in business...hoever remember the part of a 130 you want to extend hangs out maybe 1/16" of an inch...I'll check with a good friend (welder/machinist) and see what he thinks can be done besides the welding.

As it stands my X has a squat BB can and the neo magnets and pn-racing carbon brushes (all available on mini-zracer.com) and i use the stock diffs (35T right?) and only the 6 cells right now. I ran a race with 4 mRS4's. 1 was bone stock, he was destroyed by all. 2 had 6 cell packs and the orion modified motor as mods, neither of these guys could handle the extra speed...i was a hair faster in the straights, and alot faster in corners as they bounced off the walls quite a bit. The other was like crazy chassis and motor mods, he could get me in the straights, but the corners the car wasn't set up right.

RE: wheels with play after BB's. This can be remedied by adding small shim washers to the axle shafts behind the axle pin. make sure you don't put too many in that it kills effieciency. They do have to be metal as the plastic set i had wore really fast.

Good luck and keep the X alive!

Well, I guess that answers my question. Where did you get the neo mags BTW? Any ideas why they make the motor run cooler and do you know if neo mags for mini-z motors will fit? I think NML has these neo mags that are super strong. Like the highest rated gauss for magnets that size. Supposedly allow your car to stick to the side of a real car even with the batts loaded

We have as or more powerful mags than NML, email at the Shop for info!

That's awesome! Did you post to the X thread on Mini-ZRacer.com!?

dose any one know what kinda fets are on the esc????

here is a pic to show you guys

wow $8.00 bucks to add an extra 8amps of POWER.... that is cheap. prob the cheapest turbo you'll ever buy..
this sound great

thanks tinyrc

Hey 3series takumi what ever happened to those movies and pics that you promised along time ago. And also what will adding those pn-racing carbon brushes do.
