Drill the holes using a 6.5 mm drill bit and clean up the mess afterwards with a vacuum.
Assemble the foundation with the nuts and ring bolts provided. This requires temporarily
unscrewing the control stick drives L-profile fixation bracket, so that you can fit the ring
bolts with the appropriate nut from under the cockpits floor
Maker sure the foundation sits nicely on the cockpit floor. If need be, open up the holes a
little with a dremel to ensure the bolts can be screwed and unscrewed easily.
