Welcome dems.

Here is the articulation mod you will want to do:

The SE servo will give you more proportional control to slow it down, for better crawling.

Other guys on here can guide you better than myself.

The SE servo mod isn't totally necessary for a crawler. You can add other ZZ idler gears to gear it down without trashing an SE.

Here's a link to a pretty good tutorial on 4-gear and 5-gear mods. I did the 4 gear mod and it works great. I think the 5 would be plenty slow and torquey.

I got your pm but I'll answer it here if that's cool? I've answered a few pms like it so I'd rather put it here for others to see. First of all welcome to bitpimps. You found a great board for your zzmt crawler needs.

I don't have a complete buildup thread, just pics of pretty much completed crawlers.




This is an ok shot of the rear of one using a 3x transfer gear set up. This set up should work for you with the parts you have. You said you have 2 right? You will need to use your 2 stock green transfer gears then you can run a red transfer gear to a red drive gear and get decent gearing. You will need to pick up a motor set to get the red gears. It would be lower with all green if you can get them though but you'll need another mt to do it.

Some more pics with 3x transfer gear set up.





If you do get ahold of another mt you will be able to do this steering mod which works extremely better than the stock set up.

Here is a pic from the bottom. The pinion is separated in this pic but you can see what is left of the chassis and how everything is shaved on the bottom.



Random pics with body off.






Hope these help. Post up any more questions here. I haven't done a full buildup/tutorial yet, sorry.
