Placing Stolspeed VGs on a Savannah
For the main wing, place the front tips of the VGs 150mm in front of the main rivet line on the top of the spar. Spacing is 60mm for the first 15 VGs in from the wingtip, and 90mm spacing for the rest.
The easiest and tidiest way to remove the slat brackets, is just to cut them off about 12mm from the skin, along the profile of the leading edge. Then they look like miniature stall fences, and you don't have to fill the holes in the skin.
Here's a particularly good looking and simple solution.
The highest point is 18mm from the skin, and the holes are 3/8 and 1/4" to give a feature look.
