We’ve had multiple teams emailing us and asking for our CAD from 2016 so we felt it was best to post it here for everyone!
Overall we liked the drive system that year. Keep in mind that with 6 pneumatic wheels, we were regularly having to check and adjust the tire pressures so that the wheel drop was just right. If the center wheel was too inflated, we would rock too much and it would affect our shots. If the center wheel was under-inflated, there was a lot of scrub while turning and the drive would not be smooth.
Hope this helps people. Please let us know if you have any questions.
