Tamiya motors

[geofroley]

Incase you don't know what these are, these are motors that go into these little Tamiya cars that you put on tracks and will go really fast because you can adjust the power on the motor. You can find them in hobby shops everywhere but I'm wondering if these would work in an XMODS.

[Lordnukem]

The motors you are asking about should work. I know someone that is getting ready to put the plasma motor in an xmod. As soon as he has time and lets me know how it works. I'll post the results.. :)

[geofroley]

There wayyy cheaper than the Stage 2 motors too.

[dEmOnRaCeR]

They arent cheaper

[geofroley]

They arent? I thought they were.

[crazydave]

They're cheaper in the sense you can buy just one, and not have to pay 15.99 for 4 of the same motors with different pinions.

They're almost 5 bucks at Tower Hobbies.

[geofroley]

Looks like they might be able to outbeat a Stage 2 motor. 19,000 rpms at only 2 volts.

[aero528]

i happen to have two of these. i will bust out the sautering gun and try this once i get my differencal fixed. they run crazy fast in the car!! it is a lot fast then the xmod, and they only run on two AA's!!:D

But still I would imagine that these should be at least a little faster than the stage 2, if not alot.

[aero528]

when i run it in the car it is desinged for it runs crazy fast!! it also takes off like a rocket!:D

Go run, and try it, turkey can wait until later. ;) :D

[aero528]

i took the whole wire assembaly off the stock moter. i am going to sauter it back on to the tamiay moter. i also need to know how to pull the pinnon.

[aero528]

ok now all i need to do is to sauter it. the piyon gear does not want to come off!!:mad: i got it though:D it is stuck with some kinda heat treatment. it fits on the tamiaya moter perfect though!!:D i will tell you guys what the results are.

[aero528]

yes it works!! i dont know how much faster it is but it sounds faster!:D sorry for the multiple posts, but i dont know how to add pics to a post. to sauter the motor to the wires just sauter it in the exact same pattern that the wires are when you take them off an extra moter(i used my stock 26k one because i have the stage 2) here is a pic with the motor in...

[TypeZer0]

did you try running it with the motor? btw, whihc motor did you get? was it the plasma dash one?

[aero528]

my diff is blown but the car does run the moter. it runs like it is soposed to be in there. but i just need a new diff. argg!! it is just the stock one that comes in the kit. i happened to have a couple around. it says S.T.D motor. on the back(no seriosly) the moters that come in the xmod are accualy these type of moters! if you look on the back it says S.M.C. motor. my theiry is that rs just buys them from tamiya and puts their sticker on them! here are the moters side to side...

they are exactly the same on every side!:p

[crazydave]

Actually tamiya is a model company, not amotor builder. RS and tamiya do probably buy from the same source, which is more than likely Mabuchi, but just because they're both Mabuchi motors doesn't mean it's the same motor. They could have manufactured to different specs.

[aero528]

yeah thats true. here is alink to the only moter like this that ifound on the machabi site, http://www.mabuchi-motor.co.jp/cgi-bin/catalog/e_catalog.cgi?CAT_ID=fc_130rasa i really want a diff so i can try it out!! i wil go today and see if they have the parts in stock or mabye get my mom to buy me the AWD early:p

[geofroley]

Whoa that's some serious technical stuff.

[3series takumi]

i want to see that plasma dash put in someones car, they are the black motors that dont have endbells, they have some other type of end to fit the bigger comm. anyways i have blown several types of esc's tryin to run that monster. even one that claimed no motor limit up to 180 class motors (the tamiya ones are 130)

so good luck on that.

i know the tamiya torque tuned and rev tuned motors are good upgrades for these types of cars, even the hyperdash if the electronics will run it, but that plasma is just evil

you should see the size of magnetic wire it uses inside. looks almost twice the size of a stock motor.

[aero528]

i wont risk it.:D i put silly putty in my diff utill i get a new one(thurs- next thurs:( )

the new tamiya (stock motor that comes in the kit) runs with more torqe and speed than the stage two! i am going to get some of the tamiya upgrade motors so stay tuned!! i hope they will be even better!

even one that claimed no motor limit up to 180 class motors (the tamiya ones are 130)

what are the xmods?? so you are saying the tamiya motors are 130?

[3series takumi]

yes sir, the tamiya motors, miniz, minix, xmod are all 130. thats why they are the same shape and size with the exception of the tamiya plasma dash. micro rs4s and abc dtmx4 use 180 motors. if you can cram a 180 in an xmod it will haul. they have more speed and torque than 130s and they last longer

[isk8blind]

the 180 motors are way longer and will not fit in the xmod. i have the plasma, stock, and torque tuned gor the tamiya mini 4wd cars. the plasma is about triple the speed of the stock one(blue). if you use the plasma you should get stacked fets. cuz you need fets to run it in the mini-z

[3series takumi]

you may need alot of fets. my friend tried to run a plasma in his Z and it melted all the solder on the turbo he had. it was pretty funny. the fets were fine though. thats the odd thing, just teh solder couldnt take the heat it made.

[Revlis]

To use the plasma dash on a mini z you have to have a turbo and even then it will melt certain turbos, not all, but you cant run it for a long period of time without it getting very hot.

You can run the longer motors in an Xmod but you will have to take out the rear motor mount for it to fit.

[3series takumi]

i just want to see someone try :) and a nice pic to go with it. i am sure there is someone out there the wont read and will just put it in

[isk8blind]

i will if some one can donate money to me. if i can get $35 worth of donations ill try the plasma and anyother motors.

[3series takumi]

tamiya motors dont cost that much, i got my plasma for 11, and the rest for 4

[isk8blind]

i use to have a store in the mall that was all about tamiya mini 4wd cars and i bought my plasme there for $16 but ive seen them for $6 on the internet.

[FastRSX]

Where are you guys purchasing the Tamiya motors? Tower Hobbies or somewhere else? I would like to get a Jet Dash unless someone has already tried it. Please let me know if it's bettered then anything else out.

I had a Torque Tuned Tamiya motor that worked very well. Had more torque with more top end then the stage 2 motor. I was running a 10-tooth pinion with yellow plastic.

I've got one on order... I want to really put my custom FET upgrade to the test, so I figured it would be a good choice. ;)

$11 at Tower, BTW. All the other motors in the lineup are $5 or less.

[FastRSX]

So what type of Fets do you have installed?

SI4562DY or IRF7389 MOSFET chips?

Are you stacking these that will require putting a hole in the aluminum or are you going all the way through the plastic too?

Neither. I don't waste my time with those puny little chips... :p. My setup is using discrete IRL3705 and IRF4905 HEXFETs, capable of handling 77A of current at 55V. That is equivalent to having a 10x10 stack of IRF7389s.

http://users.adelphia.net/~neurokinetik/roof_revision2.jpg

[3series takumi]

that is tight!

[geofroley]

Do I need to mod the FETS if I get a Tamiya motor?

[FastRSX]

neurokinetik that's quit a set up you have going on. So, what your telling me is that I shouldn't waist my time soldering in the SI4562DY MOSFETS? I'm just worried that with the 6 cell and your set up with all the extra wire will not fit under my RSX body. Things are very tight with just the 6 cells right now.

[aero528]

not with mine, runs like a dream!! of course i am just using the stock motor. rs takes so long with parts!:mad: i ordered my diffs two weeks ago, and they still havent turned up! ohh well...

is that expensive? where can i get them? do they give you that much more power? a link to how to do them?(or just here)(or email me) thanks!!

[FastRSX]

I need to move this back up for neurokinetik to respond.

neurokinetik how did the new Tamiya Plasma Dash Motor work out? I see this mod motor pulls 3.5 times the current of the stock motors. That’s quite a bit more so something will have to give.

What are you using to measure the current draw?

[neurokinetik]

I have yet to run it in the car. I ran out of time last night at the track, for some reason my car with the FET mod was totally dead after I put it all back together. I'm going to redo all the battery wires and go from there.

I measured current by wiring up a set of 4 batteries directly to a motor, going through the ammeter on the way.

Anyway, all the info about the FET mod is here:

http://www.tinyrc.com/forums/showthread.php?s=&threadid=14725

I have heard that the Plasma Dash has been known to kill stacked setups in Mini-Z's. That's one of the reasons I have chosen to try it with my setup. BTW, it does fit under stock bodywork with no problem.

[geofroley]

Will the Plasma Dash kill the XMODS FETS?

[neurokinetik]

I'm quite certain it will. It draws WAAAAYYYY more current than even my most extreme hand wound creation so far.

[3series takumi]

yup, lets see what i have burned with it....

miniz with twin turbo (that got messy)
minix with stock esc plus fets for 16amps continuous output
minix with teamorion flash esc (went crazy then stopped... for good)
minix with novak spy esc
and i tried with my lrp quatum micro "no motor limit" and it shut down.. a few times. it wont even try to run the thing ;p

so... i have this motor and nothin to race it in. i have it in a tamiya handrouter at the moment.

... that is one evil motor. props to the first guy to use it safely

[geofroley]

Ahhhhh crap. What are other Tamiya motors that are good and wont destroy FETS? Or how do I modify the FETS?

[neurokinetik]

Well, I just tried it (Plasma Dash) in my car, and it is horrible. Complete waste of time. With the car in the air, it spins the tires fast enough for them to fly off. Put it on the ground, and it hardly has enough torque to move the car. It's as bad or even worse than the 25 turn motor I made.

[geofroley]

Well what are other good motors? Not nescasarily Tamiya motors. I'm looking for something like a stage 10 I need absolute speed.

[FastRSX]

How many batteries (or volts) were you using with the motor?

Sorry to hear the motor didn't work out. Well, maybe we can take it apart for parts. I really like the way it looks.

[3series takumi]

miniz x-speed, pn-speey, pn s01 s02 s03, GPM Modified Speed and Torque Motor

try any of those?

[geofroley]

Where do I get these?

[3series takumi]

at places that sell miniz's

i got to tokyotekki out her in california

[FastRSX]

The Torque Motor was a little better then the stage 2 motors. Had more torque with about the same top speed. Ran this set-up with red or yellow gears on a awd.

The best motor I've found is a SpinBrush. The com was polished, advance time, oiled, adjusted brush tension, and a drop of com juice. It has so much torque down low that the soft treaded tires sill doesn’t hook up. Then after being run in it smokes the 30k x-mod motors.

I must state that this is all done on a 6-cell car.

[neurokinetik]

Guys, forget about these 130 motors...

http://users.adelphia.net/~neurokinetik/bowdown.gif to the big block:

http://www.tinyrc.com/forums/showthread.php?s=&threadid=16020

[geofroley]

But those are 180's:confused: I looked up Tower Hobbies and found some Mini-Z motors that might be fast. I'll get the link up later.

[geofroley]

Actually, those motors look like their fast. . . but a 180 motor wouldn't fit in my RSX:(

[neurokinetik]

Time for a body conversion and long wheelbase. Seriously. The difference is that big.

Anyway, I found out why the the Plasma Dash performed so much like my 25 turn motor... It's actually a 27 turn motor.

Armature itself is much different than what I have been seeing in all my other 130 motors though. Take a look (Tamiya motor is the top one):

http://users.adelphia.net/~neurokinetik/pd_vs_s2.jpg

Look familiar? It should. It looks almost identical to the armatures that I see in NML motors. Take not of the "fat boy" commutator, which is of a much better quality than any other motors I have disassembled so far. Time to get winding and see what I can come up with. http://users.adelphia.net/~neurokinetik/mischievous.gif

[3series takumi]

i am not sure what makes those fat coms better, but they work great compared to a regular motor. it is the same size com used in 180class motors

[neurokinetik]

I can tell you that there are two things better about them...

1. They are more true than the other ones. Less brush wear and more consistent performance.

2. The gap between adjacent contacts is smaller, leading to less arcing and overall better performance.

[MicroRCTuner]

Check out this stash of Tamiya motors..just a few have more

http://kcchou.phpwebhosting.com/pchou/IMG_0881.jpg

[geofroley]

That 50,000 RPM motor looks cool.

[MicroRCTuner]

I was wondering would the Hyper Dash Hayabuchi motor run fine with stock ESC and everything? I want to try just switching the end caps..so I dont have to re-sodder...any ideas?

[cdog4w]

I've heard all sorts of motors mentioned in this thread, but no mention of the mini-zracer.com motors designed for the mini-z. Has anyone tried those? (maybe in another car like the mini-z or mini-x if not the xmod) I know one of them (Z-130-S-BB) comes with a ball bearing can, but is a bit expensive. For those without motor knowledge, would this be a good way to get custom performance if you have the $$?

[geofroley]

I'm using a PN Speedy and this things screams. Sucks out battery life though.

[cdog4w]

Ah cool. Takumi recommends that as well. And hes not just the hair club president, hes a member too. (unless his sig lies :)

I don't have enough space to run inside anyway, so might as well go for some nice speed when I take it outside.

Takumi, do you still have your PN-Speedy hookup with the bushings to keep 4WD or did you try out the heatshrink tubing joint? Also, when you did the xmod wheel mod, you drilled out the hole, did you have to slot a groove for the mini-x wheel pin and then screw it on with the normal mini-x lug nut? (I know you're using the xmod universal something or other now so you use their D system)

EDIT: Forgot to say thanks...

Thanks!

[3series takumi]

after switching to the xmod universals i had to get a new set of rims, happy they dont cost as much as miniz wheels. i am stilling running the pn-speedy with my drive shaft extension (made a new one out of hollow aluminum :D).i hold it together with shrink tub cause it lets the shaft bend if it needs to. it is my favorite motor. my pn-speedy has neo mags and a bearing can just to add to its power. no xmod has beat me to date. anyone in the SJ area wanna race, hit me up.
