Placing VGs on the Vertical Fin

The hinge line will likely be swept back, so orient the template each time so that all the VGs are oriented with the front tips about 5º upward to the horizontal, instead of alternating. This way all the VGs will be near the optimum 15º when the aircraft is nose high at landing and take-off when the rudder effect is most needed.

1. Stretch a line on the vertical fin 100mm (4") in front of the gap between the fin and the rudder.
2. Using 30mm spacing template, set a row of VGs with front tips along that line.
3. Repeat for both sides of the fin.
