Go to Post Haha, I applaud your efforts to read into the actions of the GDC, but I feel like trying to do so is like shooting at a target, in the dark, at a mile away, with a sawed off shotgun. - ttldomination [more]

WCD Center Drop Size?

Hi all, we're looking at West Coast Drive for our drive terrain this year, and I'm wondering if there's a minimum drop for the center? Right now, we're debating between a 1/16th drop and a 1/8th drop. We'd prefer to go for the 1/16th drop because it would minimize rocking. Would we still benefit from WCD with that small of a drop? Thanks.

Proposed Drop: (1/16th) https://imgur.com/a/dAkb3

Current Drop: (1/8th) https://imgur.com/a/2iX1b

Re: WCD Center Drop Size?

I personally prefer 1/16th with the colsons. However with that being said and looking at your cad models, I would think about using a four wheel drive or spacing the outer wheels more to the outside of the robot.

Turning ability is all about your wheelbase, and a 6 wheel drive with a drop center effectively cuts your wheelbase in half allowing for easier turning but there is a point where you can turn too easily and its difficult to control as a driver. a ~5" long wheelbase on a wide robot as you have proposed is in my opinion far deep into the difficult to control territory.

Teams have successfully ran bases with a perfectly square 4wd wheelbase (I believe something like ~20x20 on 2590 in 2013)
