Re: Pros & Cons of Carb/Swerve Drive Train.
Yeah, as almost everyone else said, 4 wheels is probably best. Crab drive is heavy as it is; no need for extra wheels and weight.

What I've heard is a major problem with crab drive isn't so much the construction (although that's a task in itself) but the programming. You have to have sensors to make sure that all the wheels are pointed in the correct direction at the same time. Then you have to have a program to make sense of the data those sensors are sending to RC. All in all it's a tough job that probably should be started before the build season.
