Bringing back the dead (ish) Crawler King

it's because the shockmounts on the axles are too narrow for an axial-width frame, so in order to use shockmounts outside the frame you have to make a narrower frame.

I've decided I want to make a reliable basher/crawler with relatively low COG, but larger tires. A crawler the kids can also play with, without destroying it.

Easiest way I have found to make spacers is a tubing cutter, and a precise ruler. I picked up a tubing cutter from harbor freight for $5 or so, much easier to cut the tubing straight, and accurately. (Length)

Cool- I basically have one of these I could use - if this is what you mean:



I have a micrometer too..if i were a bit off on my cut, I could file until correct.

Nailed it!

So the R2 Trans has a 5mm output and the wk shafts are 6mm. I'm not sure anyone still makes the adapter. :(

I'm gathering parts for this build - its going to be wonky, but it will be mine!

I've seen the adapter a few times but I didn't use it. I mounted the shaft on the output anyway. It wobbles a little bit but doesn't bother anything. I just check it every once in a while . This rig has been working good for a long time now. I'll post some up to date pics of a few small changes, most notably the rock beast tires. Hank

She's still moving forward. Learning as I go and picking up parts and knowledge/experience. Time will tell. I think the shocks I bought will be too long but i"m not sure. It will be a real frankenstein's monster. If she goes under her own power when I'm done, it will be a good start.

Clocked motor, carbon chassis from who knows what. A couple bent links I've made so far.

[Snarf77]

I'm concerned with interference of the motor with my upper links. Could someone have a look at this picture and let me know where they would mount them. This picture is from the bottom upwards a bit so it doesn't really show how close the motor is to the links. This isn't as easy as I'd hoped!





Maybe these illustrate my challenge a little better? Can the upper links originate from the same point as the lower links, meaning, can I squeeze the lower links towards the center and put the upper links on the same bar at the frame?
