That's because you moved the front forward so the spur was still in the chassis cutout. The options I am looking at require no chassis modifications at all. One of the options I tried was to hollow out a 44T spur and slide it over the diff cup. Then I was going to find a way to secure that to the stock spur. Since the 44T spur was not in line with the gap, it rubbed ever so slightly.

I think Mike and I are on the same page as far as chassis mods go. Whatever he makes will probably drop right in with no extra holes or dremel "milling" to fit. Many people are not going to want to mod their chassis, might not have the tools and/or skill to do so right, and/or want to be able to revert back to nitro (I shudder at the thought). So it only makes sense from a sales perspective to cater to the masses. And at the same time, I think he is trying to find a solution that will be relatively inexpensive. Not too many are going to want to buy a new chassis and all kinds of extra parts for a brushless kit.

You can tell he is having a bit of difficulty with trying to get a plastic spur to work since he's already spent some time with really no forward progress - just a bit of prototyping. At least it makes me feel a bit better knowing I'm wasn't the only one to have a heck or time to figure this out! :)

So, for the time being, I designed my conversion to be functional, but with the knowledge that Mike was going to come out with something. So, things are spaced so I can replace any one thing without having to rebuild everything as well. I really hope I can keep the battery tray since that is about as perfect as I could get it. It was tough to make it support 2s, 3s, and 6 cells, while holding each type firmly and arranging everything else to be neat and tidy.

Wow, another long-winded post! I gotta stop doing this...
