How long did it take for you to build your drivetrain?

[rmmlg]

Last year, we spent most of the 6 weeks designing the drive train. This didn't work out so well since we didn't have any working special features. Granted, we had a very good drive train, but special features are nice to have. Things we have decided to do differently this year:
-we've done more brainstorming during the off-season
-we plan on doing the brainstorming differently and decide on a drive train and design it during the first week, so that it can be built with time to spare in testing and practicing driving for the last week of the build season
-we weren't organized enough for brainstorming last year and didn't meet oftne enough during the first week

So that's what we plan to do differently to hopefully spend less time on a drive train and more time on special features.
