Roll axis
Pulleys 5 are connected to a post extending upwards from the hang bracket. Considering a right roll input, with
the trim cord tight (slow trim selected) then pulleys 5 are moved to the left, which causes cord 6R to tighten and
6L to slacken. The right hand washout rod is therefore pulled up relative to the left, so reducing lift on the right
hand wing. The increased tension in cord 6R also causes bending of the right hand leading edge 15R. The
asymmetric tension in cords 6L and 6R causes the wing keel to swing to the right, so tightening cord 13L and
slackening cord 13R. This causes sail trailing edge 14L to be pulled tight and 14R to be slackened.
The overall effect is to increase washout in the right wing and reduce it in the left wing. Typically the roll rate from
30 degrees left to 30 degrees right is reduced from 5 seconds to 3.5 seconds at 50mph. The wing remains
controllable in roll right down to the stalling speed.
