****What do you guys know about these motors. I actually have one, but haven't used it yet. I bought it awhile ago, just to see what it was about, and never did. Besides I wouldn't really have anything to compare it too.

If its something that could be done, i think attempts should be made till its done right! i think its possible to do! i mean, I dont think i could do it, but the concept is there!

I have seen that! My friend bought one fo those for his OVRLND. It acts similar to an S1 with neos, but slower. More torque is noticeable, good for trail driving i guess but we popped one of them open and the winding is kind of sloppy.

Because if we have the spur too big the end bell wont fit and if we have the pinion too big we will have to raise the motor brace too much, not to mention if we gave the already reduced motor a lower pinion to mesh onto another larger spur only to go into the gear-train again, the spur would probably strip if it got binded due to the tremendous torque of the motor.

Compared to other setups i have seen it would be a count of like 7 gears in the gear train compared to like the average 3 or 4, but the torque produced would just be tremendous.

Ok, just so I don't get to lost... I am imagining that the mini gearbox would fit inside a 130 motor can.. the 3mmD would have a low pinion on it. then it would just go right into the motorpod, like a normal motor, and use the matching spur gear in the chassis. And you say this would be a good set-up with tremendous torque. Sorry, if Im not picking it up quickly, but Im just trying to imagine it correctly.

Also, what about the mini, planetary gearboxes... does the planetary setup help in anyway, is is better or less effective, then how we are going right now.

[dreamingISdrifting]

are you talking about having the motor on top of the can or inside it? Either way the motor would give off a tremendous amount of torque, like TONS of it, an hs-55 gives off 15oz-in but if we strap this motor in it should be producing roughly 28oz-in which is practically double the amount of torque or in other words 1.75lb per inch! As for planetary gear boxes, for rc i have only seen them on 280 sized motors and higher, however they have reduction units if that's what your talking about?

Im talking a very simple drop in... Stick the gearbox in 130 can, so it is just like the Ver2 motor I guess... just stick a pinion gear on it. So your saying that that would be a great crawler motor.

AS far as the planetary .. im taking somthing like this... this one with all the disc is 4.25"" long... but I think I found smaller ones. How would that compare to the setup we are discussing right now..

[dreamingISdrifting]

Well i guess i would call that a great crawler motor unless your application has lots of binding, deformed bushings, huge tires and requires more torque than 1.75lbs to move it which i doubt, other than that it should be BEAST.


Wow, thats cool i have never seen a planetary gear setup smaller than a 280, cool that you found it though, how small is it for 130s or for smaller motors? Any how planetaries are actually very consistent and efficient types of gearing systems. The main flaw is that the gear options is very limited for example the first gear ratio may be 5:1 but if you add another stack it will be 25:1 and another 125:1, you get the rift? Not to mention they only come in triangle and rectangle shapes, mounting might be a pain.

I think I had found one that was just like the one from the link but small like the 100:1 gearbox we were looking at.... So if Im right and there was one that small that fit into a 130 can, that would be better? If anything, it would fit but be a little longer, which would mean, just trimming the side of the motorpod out a bit for the end to stickout.

[TripleXmodder(akaXXX)]

This one I think is even better. same 100:1, same size.. but 440rpm ... http://www.robotshop.us/pololu-100-t...cro-motor.html ... What do you think.

heres the second gen 1, not much to show. its just the motor sitting in the 130 can


heres the first gen

So this is what we are looking at doing...... (2nd GEN, 1st pic) .... but is the 1st GEN a better set-up, do to the extra 2 gears that are added. If so should we try doing that again.


PS- I think I just did a triple Post... kill me please.

I think a new crawler motor like this work... and I'd be one of the first ones to want one! That is.. if this airplane motor ever craps out on me!

2nd gen has way, way more torque than the 1st. the 1st gen aoshimas were pushing it before it would possibly kill the motor. the 2nd gen , well it will snap things before it will die.

[TripleXmodder(akaXXX)]

Cool, ok then. I was thinking the 1st GEN w/ 2 extra gears would have been better... Im gonna get this and make one... http://www.robotshop.us/pololu-100-t...cro-motor.html

Do you know how it compares to whats in that 1st GEN, or your not sure exactly. Thanks for those photos also... I did remember seeing them a long time ago.

I know I know. But, hardwood floors went in and everything had to be moved out and moved in, so I have to find all the **** again. And then get motivated.

The gear box is massive. It's lenght is about the length of the gen1's main chassis. Main issue I had with finishing this was money, needed a ESC and radio to run the motors, since it would more than likely melt any xmod pcb. But I did find a way to regear it to xmod standards, and even taller. The torque of two motors would allow you to over come tall gearing, in theory.

http://www.xmodsource.com/forum/show...ght=dual+motor




Also, small servo motors suck. They burn up rather quick, not made to take xmods voltage constantly.



Gen1 arm, neo mags, massive reduction through gears and worm gearing... BEAST, never ever ran out of power.

[taiwanesekid05]

I found my Tamiya Gearbox really top heavy though :/

[texan_idiot25]

I used pinewood derby car weights to lower the CoG, and add traction. Weight was never a negative with all the power.

[cycygrace]

id rather do nitro instead of gas or maybe a 2 stroke mix? i dont know but very good idea.

this really isnt a mod more of a trick what about a car that has actual disc brakes strong enough to do an endo? im sure it is possible if not already done but let me know

[spitfire]

For awhile now, ive been trying to make my old slot car chassis an xmod. got every working, just getting the steering to work is my problem.

[reaper]

the crawler motor discusion is getting confuzzed

what we are looking for is this type of motor


the black bit is an in-line planetary gerabox

the rpm we are looking for is around 130rpm

now if we can get one like the set-up above that fits inside a dummy xmod motor that is better

if not then it sits ontop , the armature of the 130 holdind another gear like this

[TripleXmodder(akaXXX)]

WellSWell that's basically what I got, but the gearbox isn't planetary. It has a ratio of 100:1, and options of 120,320 or 440rpm. Which of those would be best.... 120,320,440. And these can fit in the motor can.

[reaper]

nice one dude

id go with the 120rpm ,but its totally up to you

is say that rpm because the motor i had ran at 130 and was a good speed for a crawler
