Well by early next week I should have my sidewinder sv2 4600kv combo installed using the traxxas parts. But since it seems to be a popular thing in a few threads I thought I maybe I would start one for people to share their mounting solutions/ideas.
I think at this point I will be mimicking pavemaster and go with a home made plastic mount and still keep both battery compartments. Not sure about the on off switch yet. I want to try to keep the esc from hanging off the chassis if I can help it.
