Swallowtail
 
The Swallowtail was designed to be a high performance glider with the parachuting abilities of a standard. It features battens at the wingtips for chord extension. Seated or prone cable set-ups came as standard equipment. Quick release turnbuckle allows the kingpost to be dropped without undoing the turnbuckle. A wide control bar is fitted.
 
All tubing is 6061-T6 anodised aluminium. The main frame is 1.5in x 0.049, sleeving is 1 5/8in x 0.058 and the control bar legs and kingpost are 1ib x 0.065. Bushings are 2024-T3 aluminium tubing.
 
Flying wires are 3/32in 7 x 7 cable, and kingpost and wing wires are 5/64in 7 x 7 cable; all stainless steel.
 
All nuts and bolts at AN grade aircraft quality. Kingpost tangs, noseplates and wingposts are specially made from aluminium.
The sail is Howe and Baibridge 3.8oz or 4.5oz stabilised dacron, doube zig-zag stitched with non-rot V-46 polyester thread. It was available in 10 colours.
 
Seated or prone harness were optional.
