Tinker Electronics came in and the unit looks pretty good. I'm not in love with the 3D printed case but i've seen these units in action and they more than make up for it. Heck, maybe I'll CF wrap the case later. Later... yes later.
Took a measurement for the drive shaft, a whopping 41" 1/4. I happened to find someone on IG that makes custom drive shafts with the pinon plate machined so that I can bolt it right up. I noticed that the drive shaft joint hits my custom transmission bracket so it's about to get even more custom.
