This is the top of the canard, removed from the aircraft, showing the trim motor (background), and the the trim pressure spring  The device in the foreground is the pitch servo motor for the autopilot.

Both of these connect to the torque tube that can be seen under the trailing edge.  This tube moves the elevators on the canard to raise and lower the nose in flight.

After several coats of primer and much sanding, the various parts of the panel are now ready for a final coat of urethane paint.

This interesting (and expensive!) stuff is a multi-part paint that is mixed with a catalyst and a reducer, along with a flattening agent and accelerator if desired, to make a hard durable coating that cures like epoxy.

The finished panel is shown on the Panel Page. 

The wiring begins in earnest!  Pre-bundled wiring harnesses are pulled through ducts in the airframe.  There are lots of wires leading to the engine compartment  because of the many sensors that measure engine parameters.  Each of the six cylinders has thermocouples (yellow wires) for cylinder head temperature and exhaust gas temperature.  In addition, there are sensors for oil pressure and fuel pressure, and wires for the magneto, fuel pump, electronic ignition, alternator, and starter.  The trick is to get this mess into some kind of order.

This is how it looks after completion of the wiring aft of the firewall.  The wires have been neatly routed and fastened to the firewall with P-clamps.  Large cables have been routed along the tubular engine mount.

In the next session, the wiring will be carried into the forward part of the firewall, where the strobe and navigation lighting systems and fuel sensors are located, and into nose section and instrument panel.
