Beefed up the bottom frame with two of those angle braces for each roll actuator and an extra 2.5″ of wood mostly to raise the actuator up.
Roll actuator U-joints are upgraded with coupler nuts (much cheaper than the 3/4-10 rod clevis route).
Waiting for the weather to improve and waiting to get some free time so I can install these bad boys. I got the 24VDC PSU from China and tested it so I will be installing him permanently in the avionics compartment when I take the topsoil off again to access the right roll actuator U-joint bolt.
Not sure what I am doing with the springs yet… not sure if these beefy actuators will fit up the middle now!
Bidding on an 5850 Eyefinity 6 card so that I can test the frustums, angle offsets, stencils, etc over the winter. Waiting for an answer from ATI about the 2×2 plus 2 extended configuration (mixed mode).
