Five variables are used to obtain the five modes of deployment. Trolling Speed D. Length of Line Paid Out E. Leader Configuration for Lure Size and Weight 1. The tail and fins swing as it is slotted and has a thumb screw hold down. The underside of the tail is indented to assist in setting the tail. The amount of tail swing used for a given tow point and trolling speed will produce an induced roll.
Induced roll is the result of yaw acting on the tow line.
Yaw is created by the displacement of the tail fins right or left. The net effect of the roll is to decrease pitch or dive angle. An increase in trolling speed also increases dive angle. Moving the wing forward one screw hole results in having to go faster to get the same dive angle. There are eight tow points.
