Four wheel drive question

[haverfordfords]

Hi all,

For those of you that are creating robots with four wheel drive, how are you accomplishing this? The included gear box only supports two wheel drive and in order to get it to work four wheel drive you need two of part # FRC-2005-112-009.

Innovation First claims that they, "do not sell the transmission gears or sprockets individually. The gear you are looking for is included in the transmission kit. We only sell transmission kits in complete sets."

A complete set would be ridiculously expensive. My question therefore is how do you go around this technicallity to support four wheel drive, OR how did you order the two parts for four wheel drive without buying the whole set, OR does anyone have any extra of these parts?

If anyone could help out this rookie team, we would greatly appreciate it.

Thank you all,
Jason, Team Leader 1656
