I have built a few crawlers that use the pede tranny for the center trans. Question is, do you know where to scare up a locker for the pede diff? I once saw one on ebay that had a solid center shaft that connected to a piece of al that replace the cover of the diff. It eliminated the spider gears and outputs. Wish I could find that item agin, my slash has terrible diffing out problems.

The Wheely King and AX10 use the same differential gear ratio as the MT2, 38/13. And now that I think about it, I could unbuild my not-quite-so-successful "direct-drive to diff" MT2 18SS for its front end and hardened differential gears.

As for the Stampede tranny idea, it'd work if I were planning something more conventional... Which just isn't me. When I can help it I don't use transmissions for 4wd (of all my 4wd vehicles my Dark Impact has the closest thing resembling a transmission).
But if I were to use one and lock the diff, I'd go straight for JB Weld. One time I locked a 'Pede diff using JB Weld and left a little grease in there. When I went to remove the JB Weld "locker" it pulled right out, thanks to the grease.

On the topic of what will go on the center, what are your guys' thoughts on direct-drive to diff? I ran the numbers and it looks like a 2826/05 (900 kv) would work almost perfectly with 4s2p A123, giving a top speed of 40-45mph. This would be super lightweight, with great overall efficiency (which as we all know means longer runtimes).

I haven't looked into the Goliath axle, do you have any specs on it? But to me it seems like plastic TC3 diff gears might not hold up to the abuse of almost 4.5" tall tires.

Buggy front end, as in 1/8 buggy? If I went that route the front end would be under-driven which wouldn't be easy on the front or rear end (3.31:1 vs. 3.92:1). The AX10 axle in the rear is currently a possibility, depending on its track width, since I want to match the Slash's track width to fit the Slash body (actually the Proline Hardcorr). I commented on the center tranny idea above.
