6DOF Project, design considerations

If you have a heavy pedal and wheel set for racing, be careful that your actuators at the back can handle a centre of gravity that is forwards from your midpoint. Love the cardboard test model!

I think the pedals don't matter much but the screens will be heavy. So yes, I can move the joints forward (from orange to the yellow triangle in the picture) to better match the center of the nacelle to the center of the hexapod.

For the motion kinematics this won't make much difference. I'd gain a bit pitch angle range because the front doesn't reach that far out as before. But this will be mostly cancelled out because I need more surge to keep the COR near the pilot's head.

I know that I will almost surely have to bolt the base plate to the ground or use lots of sandbags or other heavy weights to keep it from jumping. Rigs with the actuators placed around the rig have a bigger base so it's less likely to tilt or jump. But don't worry, I have a friend who is a stonemason. He can get used gravestones for free.
