Im having trouble picturing the three point attachment thing - Can anyone help me to visualise this? All the ones I can imagine have a single hinge, plus one or more rams. When we say 3 point - do we mean those where the flipper is physically attached to the ram, which itself pivots? Or is there more to it than that? If this is whats meant by three points, then presumably in the absence of tethers, gravity becomes a single point attached flipper whereas in this thread it keeps getting referred to as a 2 point....

Cheers
