As I had a lot of fun testing my Crawler-Z on our OL-Track in the Community Racing Center Oberkirch (CRC) / Germany I decided to setup my own track in my garden - just 1,5x1,5m and not yet ready, but here's (http://datenklo.net/file.php?id=b9d2ab1aE6343a27a06AC9d1c90d1B33A7BA88 AB40bDa3AbfbB) the link to a little video - enjoy !

... not yet ;)

I just done the LSSM-Mod, mounted cooldragon's rims and tires and installed a lemo-solar motor. That's it !

i have a LSSM mod on my monster to, great for crawling !

but wat the h*ll is a "lemo-solar motor" ?????

You can order it at www.lemo-solar.de - search for :
"Truck Trial - Antrieb für M 1:87 (Bausatz)" for 29 Eur ...

interesting !! the gear ratio is perfect for crawling ! but how did you build in that kind of motor ??
Do you have a photo how you installed it ? Did you have to make an adjustment to the circuit board ?

You have two possibilities - either you install it without the additional gear, then you don't need to make any modifications (just adjust and fix the motor with some plastic/hard foam) or you do it like noumenon from our german forum:

There are no adjustment on the board required - veeery easy ;)

mmmm.... very interesting !! i'm going to try that ! i am searching about a year or so after a good crawling motor but i searched in the 130 class motors...

thanks for all the explanation(s) and the photo !
...you will hear from me if its done ;)

avant
2006.07.12, 12:58 AM
... for the 130 class motors I can recommend the Topcad R2 in a BB case. Loads of torque and if you own a Helios, Mars or similar, you just use -100% TH CURVE - also excellent for crawling and cheaper than the lemo-solar motor, but the R2-solution definitely needs a good transmitter and a fetted board ;)

Lemo-Solor doesn't ship to the usa, as far as i know. That's the only problem with the lemo-motor.

Check out this thread (http://mini-zracer.com/forums/showthread.php?t=18405) for a diffferent gear reduction setup. You can get the mentioned sanyo gear motor (as well as a cheaper alternative) from www.solarbotics.com

An easier way to use the gear motor is described in this thread (http://549.rapidforum.com/topic=102178968346) in a german forum

The user skaos monted the gear motor in an empty 130 motor can, described at the end of the thread. A great idea!

i think that shipping will be no problem... i'm from belgium ;)

to use the 130 empty can is a great idea but then you can not use the gear reduction i think ??

The gear reduction lies "inside" the (sanyo) gear motor :D

I am not sure about the speed (rpm) of the stock motor, let me say 8000-10000 rpm without load. Maybe the speed with load is at 4000 rpm?

If you use a gear motor inside a 130 motor can (replacing the stock motor in its stock position) you are using the stock gear box. Since the gear motor has a reduced speed (in rpm, depending on the gear motors ratio) you will have a reduced speed of the overland.

Assume that the stock motor has 4000 rpms (with load) and you are using the Sanyo GM11 with 75:1 instead, which has only 246 rpms, than you will get a reduced speed of your overland in the ratio of 16 : 1 (aquivalent to 4000 rpms : 246 rpms).

You can calculate the resulting speed of your overland, by multiplying the ration of the stock gearbox with the rated rpm of the gear motor (check the data sheet at the solarbotics homepage).

diets - too much speed, or not to much speed :D

newbitowner - I've just tested the download four you and it still works fine for me. You have to wait 15s and after that period click the button and the download starts ...

got my second hand OL today, it already has lego tires, LSSM and a BP special !

now i just need a nice crawler body and that lemo solar motor !! :cool:

diets can you take a picture of that lemo solar motor without the motor clip so i can see how you made the connection from the lemo-solar gearbox to the stock gearbox ??

thanks in advance !

ps did you use the lock plate to lock the diff ?

I don't have a lemo-solar, so i can't make the requested pictures. I use the Faulhaber motor.

Keep in mind, that there are two different types of lemo motors.
The mounting depends on the type of motor you have.

vertical
The one shown on the picture you posted, is mounted vertical. Motor type #MU915L.
Maybe this link will help you!
http://549.rapidforum.com/topic=102878968346&startid=2
On the second page, there are a lot of pictures how to mount the lemo.


horizontal
It is the one sold by www.lemo-solar.de. Remove the worm gear (if it is mounted, you don't need it).

http://img96.imageshack.us/img96/1647/11434b1hg.jpg

Use one of the stock gears of the overland (i don't know the size, just use the one with the best gear mesh). You have to dremel the motor clip a little bit.

thanks diets !!!

but if you use it without the reduction(gearbox) with the motor horizontal does'nt go to fast ??

on the german forum i saw something about the lemo-solar with gearbox makes the OL go about 5m/minute but how fast does it go without the gearbox ??

@jaeneke

5 m/min?

I am not sure :rolleyes: As i mentioned earlier, i have no lemo motor, so i can't help you with the speed question.

But it should be much slower as the stock ol. Just give it a try! And, more important than the speed, is the increase of torque. You don't have to push the throttle to maximum to climb (more a jump) over obstacles.

You should watch the video of my awd (on the second page, the picture with the pajero) (http://mini-zracer.com/forums/showthread.php?t=19284&page=2), this will give you a idea of the resulting speed (i am using the sanyo gear motor in this setup, but the speed should be similar)

i thought i saw something of about 5m/min and i don't think i misunderstood because i can read german pretty well...

and i saw that video earlier, this is your's ?? i have this video on my harddrive because i'm a huge fan of that car :D

i think i'm going to go for the solar motor with reduction, in need torqeu, torqeu and... ....torqeu ;)

in fact a few of my buddies at our belgian forum (ggtuning) are enthousiastic about my crawler project and want to buy the lemo's to just for crawling !!

How does this look? I was messing around with swapping some parts.

If you take 3 parts from a MZM and transplant them to the overland , PLUS move the front suspension pin foward to the front hole.
You will have a CJ-5 Overland as if it were production.
All the shocks are perfectly aligned and smooth as silk. :p
and the Super Swampers dont rub at all on the battery box what so ever.
Body aligns perfect too. :rolleyes:

hey that is smart ! i never thougt of changing the shock tray's with my MZM on my OL...

but you can also change the body posts with a OL, ok this means glueing the posts but it just as simple ;)

i thing i'm going to put my 'mad killer' MZM body on my OL like you did so i dont heve to ruin a good OL body for posts !

tnx for the tip !

That's a pretty cool way to mount that motor drilling out a 130 end bell. If you want a 1/2x 4x4 crawler you want one of these:
