well iv been here for a wile now posting a little lurking alot

im an xmod guy through and through but a few months ago i got some zips in a joblot of xmod parts , after finding this site i was inspired to build a crawler

well this is her as she stands now this has been my rest break project i.e just doing small amounts every now and then
i started with the articulation mod (well der) then went on to add gears to the main drive , this im not so happy with and will be changed (see below)

ok enough chit time for pics

so as said above im not happy with the drive so this will be my new main drive

and also found this for the steering

Looking good, it's been a while since I've seen a truck build.

Interested to see how the planetary drive fits for the steering. The one I used was shorter ( 20:1 ) but I added a couple steering gears as well. What's the reduction on that one? It's a PITA to fit the pinion too but they work well.

Drive motor looks good but I had issues with the length there too.

And where is the pizza from? The picture on the box looks good.

I must be hungry.

wow the man himself

just so you know i stole er i mean borrowed most of my ideas from your builds

the 6mm motor is a 1:136 ratio giving 200rpm @ 3v i haven't got it yet but its on its way
at the moment the wheels wont even turn when on carpet so even if slow at least they will turn with that motor
yea i can see the problems that will arise fitting the pinion but will cross that bridge ...

the drive motor is in and works great
1:26 ratio giving 250rpm @3v this is about perfect when run through the stock gears on the MT

@ sidewinder
got the munchies dude ???

I actually drove to the convenience store after that post and bought a frozen pizza, oh, and got a hot dog and giant Coke while there. So, yeah, maybe.

Great looking truck! The steering gearmotor looks sweet!

I can see why that inspired him, the pizza was in focus.

thanks man
praise from you guys means a lot iv seen the kickass projects that you all have pumped out

i will get a vid up of the drive motor and the steering when it gets here

and i better learn how to use my camera and get some good pics

624:1 by my calculations using the stock green gears. Nice.

3x spur gear mod netted me 448:1 IIRC. Se gearbox is significantly lower. What I really like about those planetaries is that you may not need to rob parts from discontinued models.

Hope to see pics/video soon. Got a link to where you picked up the planetary motors? I'd like to check out some specs, thanks.

at the moment im running a pinion made from a gen1 xmod servo gear as they are the same size shaft so ratio is a little higher , but a stock pinion will work with a bit of modding

hers is the link they carry ALOT of micro motors including the main and steering motors ive used

i think ive sorted my camera now so here are some small updates

as said i have got the main drive motor in and working great
i have also been messing with some new shoes and wide axles as well as trimming to get more throw in aticipation of the soon to be new steering motor

reaper · Post by **reaper** » Tue Feb 09, 2010 4:03 pm

a little vid for you guys , just to show the size and articulation

also got the new geared steering in so near the end you can see how slow
and torquey it is

THAT is REALLY cool, Reaper!

And I like the Top Gear back drop
