This strip, which is the motor mounting plate, should be canted 5 de- grees below the stringer. See Figures 5 and 6 to get a better idea Figure 9 (Top).

The object is to mount the motor tube 5 degrees angled downward relative to the centerline of the fuselage (the par- allel stringers you glued in are also parallel to the centerline). Now take a 5" piece of 29 mm motor tube stock, and position it with 5 degerees downthrust right on the motor thrust plate, which you have just smeared generously with epoxy. When the epoxy is set, repeat the process of installing the motor pod on the other half of the fuselage. Now smear epoxy on the remaining vertical edge Figure 12 (Top).
