it is simple .. we want YawVR ... nothing else ;-)
first. check the price of the competition for a 3dof, then ask someone who is really into manatures how much they have spent. talk to people who do jeeps, boats, or rc planes. going this deep into any other hobby is much more expensive.
the pod design is better than platform, because the platform needs the throw you to the left, giving you a rite jurk of force, before you feel the left g forces. the competition is also not nearly as portable, or nice looking. i know someone plans to get the moon skin, and use it as a centerpiece decoration when not in use.
