Hi all,
The wing warp control lines were attached to the base of the rear interplane struts on the lower wings.
The two control lines were routed between the lower wings through twin pulleys, mounted on a support frame in front of the cockpit.

Mono-filament lone of 0.08 mm diameter and routed through 0.2 mm diameter holes above the pulleys.
'GasPatch' 1:48th One End turnbuckles fitted with 0.4 mm diameter blackened brass tube.
