Possible idea for bringing brushless to the pit party (as in racing)

Pit stops are the next step in E-1/8th racing. I hope some of the geniuses who frequent this forum can come up with a winning design. For the next few years I'd say E-1/8th will be run with Nitro, maybe when it starts to catch on, we can be in our own classes, until then we have to beat them at their own game. That means "race weight" and running for 30mins....
