Replacement Diff Connect Box for [Axial AX30401 HEAVY DUTY BEVEL GEAR SET 36T 14T](https://www.axialadventure.com/product/heavy-duty-bevel-gear-set-36t-14t/AXIC3401.html) to fit into the stock axle of the [Red Cat Everest-10](https://www.redcatracing.com/products/everest-10-1-10-scale-crawler-2-4ghz?variant=31050558701658) After trying several different options to reduce the torque twist on the Everest-10 and doing plenty of research from other people more knowledgeable than myself on the internet, I found references to overdriving the front wheels to solve the torque twist problems, as well as increase steering authority (the Everest-10 has notoriously bad steering radius). In the thread i was reading about it, someone mentioned that the [AX30401](https://www.axialadventure.com/product/heavy-duty-bevel-gear-set-36t-14t/AXIC3401.html) should be a drop in replacement, but as it turns out they were wrong. The Connect box is too big, and has a different seating pattern. I created this replacement box so i could use the overdrive gear, and it is so far working great. the torque twist is almost entirely gone, which is awesome. I have other modes like pen spring preload, shock tower extensions, and lower link repositioning that could be helping with this as well, but up until replacing this overdrive gear it was still twisting pretty bad with all of them done so I think this is the main contributor to it working better now. I printed it with 50% infill and it seems to be plenty strong at that level. I forgot to test the steering radius before the change to determine if it has helped at all. I remember seeing a video with someone showing the stock radius, i may use that as a baseline and post a comment with the current radius I am getting out of it to see if there is any improvement.
