Seen a video of one on youtube with that as motor but language barrier. Looked very smooth and torquey but also, very slow. I have one on the way, just need to figure out how to get a pinion on there.

Yeah no room - the length is fine but the output shaft on those is a 3mm D - the trans is looking for a tiny 10t pinion on a 1mm or 1.5mm shaft and there isn't enough room to mount anything much bigger.

[Brake Weight]

Can you bolt a brushless motor onto the gearbox to get a speed/torque medium?

[Heckler]

I have one of these on my bench at home and like said above the shaft is way to big to fit a pinion on, and the motor itself is actually smaller than the stock motor.

I am but with a redcat tranny.

All the talk so far is transmission and a little on axle width compared to the d90 shell.

Have any of you sourced any cool body shells, ones that fit width wise, accepted wheelbase might be wrong.
Any findings on rims, maybe tuck under more without rubbing?

I have a hilux shell Bill that should be spot on needs a slightly longer wheelbase
Will need a fe bits removing and some little holes filled but has potential.

122mm total width across the arches
165mm ish wheelbase

[Sparks1337]

Aah Dready you jammy jammy get! That is just lovely.

Is that the 1/16 Nikko body or something else? I have the 1/20 Nikko Hilux but it's way too small for the gelande. The trouble is the gelande really needs a 1/18 body - 1/16 is a bit too big and 1/20 too small.

There don't seem to be any suitable plastic kits at that scale and old RCs tend to be either 1/16 or 1/20. I've spent a few years looking, as I always felt the micro wheels were too big, and I've yet to come across anything.

At 122mm it'll actually need offset wheels, and possibly a larger diameter as well to look right.

I have a couple of old radio shack/tandy bodies based (loosely) on a 79 Ford, but at 130mm width it is way too big for the gelande. The first one went on to a venom mini giant and I've yet to find a use for the second one:

I've seen the same video and it seems to work great. On his he has ditched the transmission and is using two of the winch motors hooked directly to the driveshafts somewhat like a MOA but retaining the shafts.

Any of the micro Crawler wheels and tires should fit fine. RC4WD, gearhead,Danally, Jim "Fungi" or any of the previously discontinued wheels for the micro Crawlers. Its the standard losi micro/Redcat sumo crawler wheel, tire, and 7mm hex size from what the specs show.

Hi everyone,

Got mine today and wanted to swap tire and rim but I can't unscrew those tiny M2 nuts using a traditional tamiya T wrench. Any suggestions would be greatly appreciated.
Thanks.

I used a " 4mm Socked Wrechch" similar to this on the Pic...

Seems like it would not be a massive challenge to design and 3D print a dual motor mount for two of those little geared motors. They could be next to each other and opposed, with each connected directly to its respective driveshaft. The stock trans is almost too pretty to ditch, but it's borderline worthless

[Shape_Shifter]

I will build the 3D model if you have a printing source.

[spoo76]

I wouldn't say the stock transfer case is worthless. The axles are just geared high. That seems to be a common problem with axles in this scale, the Sumo and I think the RC4WD micro Trex axles were geared high. Maybe it has something to do with getting enough gear in this small size? I don't know how Sam's 1/18 axles are geared however.
You could get more reduction by going to a divorced motor setup a few different ways, I don't think I've seen that yet.

If you happened to see the modification i made to my transfer case it allowed for a divorced setup. i used a losi trail trekker motor and trans which seemed to be a huge improvement, when i tested it out on my bed it was able to crawl up and over pillows with ease, i even set up one of those aluminium macbook laptops at about a 45 degree angle and was able to drive up it and when i stopped at the top it slid down slowly without the wheels spinning so the setup i made had enough torque to create a drag break useful for crawling. however the lowest revs i could achieve were just a bit too high for a crawl speed so i guess im going to give one of those geared motors a try.

Also for those interested ive made a leafspring setup with new shocks and extended the wheelbase out to about 155mm and am planning on making a lwb body for it so maybe like a pickup or wagon, haven't fully decided yet but ill be making a build thread in the near future

[Aeronuclear]

Hi has anyone tried to fit an Orlando F150 1/35 reduced gear motor onto this D90? I have the Orlando F150 and there is plenty of torque from the motor. But it's for a 1/35 rig and is all plastic. So lighter and smaller wheels.

Link to the Orlando F150 motor.

This is the 120rpm one, but a 200rpm one might just be good for the D90?

Did you try a bigger spur and or smaller pinion with the divorced setup?

if your referring to the pinion gear on the losi transmission i have the smallest one installed on the motor and what ever spur gear it comes with in it

[spoo76]

Now that it's divorced you should easily be able to fit the 59t and 60t spur gear from the losi micro rally/SCT. Should be a nice improvement. More torque and slower speed.
