Zephyr (oz1089)

About this Plan

Zephyr. Control line combat stunter, for 2.5cc power. Model Aircraft March 1956. 38in span.

Quote: "Here is a combat model worthy of the designation. Of simple yet strong construction, it should easily withstand the rogours of control line flying. Zephyr has a number of successes to its credit, including a first, with an E.D. Racer powered version, at the London Area Control line meeting held at Heston. As a matter of interest, it also has a good speed performance having been timed at 83.6 mph. over 20 laps using a 9x6 polished Stant propeller and powered by a modified Oliver Tiger.

Wing. Start by cutting out wing ribs, not forgetting the slots in the port wing ribs for leadouts (note rake on leadouts). Carefully pin all the ribs together and mark off, cut the main spar slots and LE slots, then remove outer ribs and cut slots in centre seven ribs for hardwood spar. Next, pin the bottom spar on the plan and cement ribs in position, then fit top spar, ensuring the ribs are upright and square; then cut and add trailing edge, holding in place with clothes pegs until dry.

The next step is to fit LE and hardwood spar, cementing well. Cut ply bellcrank mount, drilling small lead holes for the woodscrews and screw in place and also apply cement liberally. Add sheeting and capping strips and wing tip blocks carved to shape, then sand all over..."
