10. Rear seat: The center of the floor in the rear seat has non-slip hard point for stepping into the rear seat. There is a gimballing vent on the left. A footrest holds the passenger’s ankles / feet in a comfortable position. The geometry of the rear seat has been modified to a slightly more upright position by a spacer behind the seat. A guard keeps the passenger’s right leg from coming into contact with the control tubes. Passengers have commented on the fact that they have not been uncomfortable, even on long flights, and have been able to read and sleep etc. with no problems or complaints.
11. Engine mount extrusions: Per plans engine mount fittings call for 1 inch by 1 inch angle aluminum bolted and bonded to the top and bottom of the center section spar. 1 inch by 1 ½ fittings were instead machined from 2024 T351 aluminum for 86EZ. The wider mounting surfaces that bond to the spar and longerons were vapor blasted for maximum flow adhesion. The forward end of the upper fittings are extended forward of the spar providing a mounting hard point. Corresponding hard points on either side of the rollover structure provide mounting points for installation of a long-range fuel tank in the passenger compartment. Electrical connections are provided for an electric fuel transfer pump. A second fuel tank vent (for such a long-range tank is installed on top of the aux. Fuel tank.

12. Brakes: Rosenhan (now Matco) brakes are used. Heat shields are installed to keep heat from the disk from radiating to the gear leg, brake line and brake puck. Axles have been machined with a 3/8” mounting flange and a fillet as the axle diameter transitions from 1-inch diameter to the mounting flange. The original Brock axles have a ¼” flange and no fillet, and several have reportedly broken. The axle is thermally isolated from the gear leg via the use of fiberfax ceramic felt.

13. Under the cowling: Generally, the engine compartment stays very clean due to the absence of oil from the engine leaking and blowing. The mating surfaces of the crank case were lapped true and flat prior to assembling the engine, and all mating surfaces of engine components and accessory case were likewise trued, degreased deburred and sealed prior to assembly with emphasis on no leaks and an oil tight seal at all points. Due to these efforts, the engine leaks very little oil, and the entire engine compartment stays clean.

c. B & C alternator. These units have been tested running for days in a fully shorted configuration . . . virtually indestructible. It puts out about 12 amps, which will just handle the entire “everything-on” electrical load, including landing light, position lights and strobe.
