OK did a few test on the rig yesterday and happy with the results:

1) the foot
2) the Ankle
3) the Knee
4) the Upper Leg
5) All together

Again no piston or wires yet - working on them next. Really chuff I got the knee set up not to move with the lower leg - I thought that was going to be hard but was very easy.
