180motor in XMOD
 

nice little fit. pic is a little blurry though.

is that the same size as a micro rs4 motor?

I beleieve so but dont quote me.
I just come up with outrageously retarted ideas because I know nothing of r/c's and my friend figures out a way to make it work. This is a pic of my friends supra. my xmod is just a rewound stage2 at 30turns with 6cell modThe 180 out of a tamtech completely smokes mine. He has also put a small sheet of aluminum to keep down flew and it still made the AWD slip up front. So ATM this car is only RWD. We have yet to find a set of tires hook up enough to drive it well. The foams slipped horribly and so do the stock slicks. Next mod is a model body and treaded tires. NOTE* this 180 only runs on 4 duracell AAA NiMH batts!!

Tamtech, huh? Interesting... :cool:

Funny you should mention that, as I spent most of last night researching alternate motor sizes. A FC-260 can would just barely fit with custom motor mounts, but has about 4x the torque of the 130 motor...

180 motor is a pretty easy fit, however. Exactly the same dimensions except the length, whuch is no problem if you are running one of the long wheelbase cars. It probably wouldn't fit in an RSX.

Hmmmm....

Yes. But the more hardcore Micro RS4 motors go to a larger (round) type. I'm going to try one of the high speed modified 180 motors in my car and see how it works.

Decided to try and put the motor from my micro rs4 in it. As soon as i get a pinion puller i can try it out :)

I'd love to use I micro rs4 motor such as this: http://graphics.hobbypeople.net/gallery/255065.jpg
but there is no way to tie the rear down.

Well, I popped in the Team Orion stock motor from the Micro RS4 in mine, but of course, I couldn't leave well enough alone. ;) I removed 10 turns per pole on it. I used the 11 tooth pinion and blue gear, set it down, and the car accelerated like a rocket.

Backwards. http://users.adelphia.net/~neurokinetik/doh.gif

Anyway, Seeing how this car moves, I am convinced that the 130 motor is lame, and will not be devoting any more time to it. On to bigger and better things. :D Even with the tallest gearing (and I have taller gears on order, hope they work) the car still accelerates like my tweaked stage 2 drag motor, which left a few jaws open at the track when I ran it, and even better than my hottest 130 mod motor to date (stage 2 reduced to 44 turns, Neo magnets, timing advance, BB can) :cool:

OK Draconious, we need Neos for 180 cans now... :p



*EDIT*

Got this thing hooked up correctly this time, and took it for a spin around my living room and kitchen. This is crazy. It far surpasses anything else I've tried in an XMod. I was doing AWD axis spins out in the kitchen, and in the living room, the cat is having a much harder time jumping out of the way. :lol:

Wow i really want to try this stock motor out now. PLus theres some dynamite mod motors at my LHS that i can try out :) I just need a pinion.

I've got a GPM high speed modified on order, along with a couple of larger pinions. :cool:

what motor is in that top picture? it's a black can but i can't make out the writing on the label

so do u have 2 fabricate a motor mount fer d rs4 motor 2 fit... also wut r d specs on d motors like revs and such, finally by accelerating hard 2 u mean spin tires


btw how much r they and how do they compare to the Nml stage 10

"MICRO MODIFIED MOTOR" thats what it looks like..

neurokinetik where did you find larger pinion gears with the right pitch?

know any details about it like #turns or who makes it?

Neuro - I have a few concerns about these motors... the stock winds, the torque, the current draw, the ability to move around in the rear,... how do you address these? (not you personally but in general ;))

If you think that the stock fets can't handle it, I may have to PM you with a proposition :p.


sherif

i was wondering some of the same things, especially whether the stock electronics can handle the power usage from one of those motors as well as how to mount it.

ok... wuts d specs on the motor??? and how hard is it 2 install and of corse whats the $$$

Well, I tested the current draw on the Team Orion stock motor that I am running (mine has been reduced by 10 turns) and it pulls 0.64A, which isn't much more than a stage 2, and is considerably less than the hotter 130 motors are pulling. As for mounting, there are holes in the front of the motor to screw into. Holes could be drilled in the motor mount to securely fasten the motor in the front. The rear is held pretty tightly against the steering servo.

As for power, well, I can do axis spins (AWD donuts) in the kitchen with this setup. I won't know how it compares to NML stage 10 until I run somebody who has one.

Cost of the motor was $13.99 locally. I don't have specs on the motor, especially since I modded it myself. Suffice it to say that by sound, it's a little faster than a stock stage 2, but the torque output is in another league. Even my motor with Draconious's Neo magnets is weak compared to this one. Install was easy, just remove the rear mount. It will only fit in long wheelbase cars, however. (All but the RSX)

I found pinions at www.hobbyetc.com, but I won't know if they actually work until tonight when they arrive, along with the 30000 RPM 180 motor that I also ordered.

I'm contemplating swapping the motor out of my weedwacker into my civic.

In a real civic it would be a power increase
:p

LOL, no doubt

hey izanuff, do you listen to 311? the "you can't fade me" in your sig leads me to believe so...just a question.

neuro, any luck with the pinion and motor that you bought?

Those pinions won't work.

Actually, I should clarify, they could work, but not that well. The pitch is closer than others that I have tried, but it still is not exact. The actual gear size is still different. The 10 tooth I bought is about the same size as a 9 tooth XMods gear, and the 13 tooth is about the same size as the 11 tooth XMods gear.

The other problem is that you have to mount the gear with the set screw farthest from the motor. If the motor shaft is too short (a problem on spin brush motors and the 180 motors) the set screw will barely cath the end of the shaft and the pinion will wobble.

They might work on a standard XMods motor, but due to the size, you won't get the full benefit of the higher ratio.

As for the motor, it hasn't been installed in the car yet. It runs very quietly and smoothly, as it has a balanced armature. I do suspect that it is timed to run in the oppposite direction, though, as it sounds better in reverse. :mad: Right now, it does not spin as fast as a stock stage 2, even though it is supposed to be a 30k motor. (That is at 7.2V, however) The Team Orion motor that I tweaked will be faster than this one stock.

Wednesday nights are my nights to test and tune at the roller rink, so I'll have more to report later on tonight or tomorrow.

alright!
 

Yeah, let me know what works, b/c I can't wait to go down to the LHS and get a MRS4 motor and drop in there! Anything that will disrespect the Mini-Zs...heh heh heh.....

when you do your testing tonite, can you check how well those pinions mesh with the xmod gear that turns teh rear diff? size may be off but maybe there's a chance it'll still mesh well enough to use on a regular basis.

? ? ? ? ? ? ? ?
 

So will those Big Round RS4 motor's in an Xmod ? or do i have to get the ones with the same shape as an Xmod motor ?

Re: ? ? ? ? ? ? ? ?
 

....same shape. Thats pretty much the Stock HPI motor and the Stock Team orion motor and dynamite makes a mod motor that the stock shape.

The current choices seem to be the following:

Team Orion Elite stock motor for Micro RS4.

GPM high speed modified motor
GPM high torque modified motor

Dynamite Mini Mod Motor

HPI Micro RS4 stock motor

The GPM high speed is decent, but not as fast as it could be. The Team Orion is pretty slow (in top speed) stock, but take off 10 turns per pole and it becomes pretty formidable (same or better top speed as stage 2 but incredible acceleration). I could probably take off another 5 turns or more and still have more than enough torque. The others I have not tried, but I thought that the Dynamite was listed as a 45 turn motor, while the GPM high speed is a 35 turn motor.

Other than the rare leftover Tamtech motors, I can't find or think of any others.

How is the HPI stock motor neuro?


sherif

any of those you listed work without any type of FET upgrade?

I'm running the Team Orion motor with 10 less turns on my car without the FET upgrade. It only draws slightly more current than a stock stage 2 (640mA vs. 580mA). I ran it all night last night, two sets of batteries, no issues.

The GPM motor only draws as much current as a stage 1 motor. It is VERY safe for the stock FETs. (240mA)

Out of that whole list, I don't think any are unsafe on the stock FETs. Not sure about the Tamtech motor, if you can actually find one. The best part is that none of those motors is more than $13.

I was cleaning out my toiletries drawer earlier today and found a Colgate Actibrush (spelling?) and it has a 180 motor in it. Soo... I smashed it and am going to try it tomorrow when I wake up. Hopefully its decent but I'll report back... This could be the new SpinBrush!

This is the style I had:
http://www.colgate-pressenews.de/actineu/actibr.gif

sherif

so I wired it up in reverse like the xmod motors are just for preliminary tests... This thing has sick torque just like the spinbrushs' do stock... but low low rpms... sooo I probably won't even bother trying to pop a pinion on here right away, I'll probably pull it apart & rewind it to 47 turns of 30 gauge. I'm betting this thing has high winds of a high # gauge wire. I'll post my findings tomorrow.


sherif

Put less than 47 winds on it... start with about 35 or even less. Remember that one turn on a 180 motor is a much larger amount of wire than a turn on a 130 motor.

Well just a small update... this thing is a pain to get apart... I haven't even opened it yet b/c it uses 4 small tabs to hold the top on and they're impossible to get loose. They're not as long as the 130 cans' so it's hard to a good grip on them. I'll probably just to go the hobby store today and pick one or two that fits my desires ;) maybe they'll have armatures but I'm doubtful.


Neuro, thanks for the reminder man, I can't believe I almost forgot that :D


sherif

They are tough to open. I gave up on the tabs, filed them off, then soldered the endbell back on when I was done.

Parts for the 180 motors are even harder to find than the 130. That's a drawback.

Here's a really cheap 180 motor. Good candidate for rewinding and experimentation. :cool:

that endbell isn't removable so it would be kinda tough to experiment with it
