These are the completed airframe parts before sanding. The parts were sanded with 220-grit sandpaper and then with 400-grit sandpaper before covering.

With shaping completed on the hatch and nose of the fuselage, the hatch is held in place with two dowels in the back and a magnet in the front. A short dowel keys it in place.

Small plastic guide tubes for the pull-pull linkage are placed to provide exit points in the covering. Sheet four of the instructions explains the routing of pull-pull lines and location of the tubes.

Installing the radio shows how little room is available. Removing some of the bulkheads in the hatch provides room for the battery.

The optional electric-power pod, included when you buy the e’SinBad the Sailor kit 36, is inserted on the wing joiner wires and sandwiched between the wings.

The SinBad exhibits docile flight characteristics in the air, yet it is responsive to control inputs using rudder, elevator, and throttle.
