Durafly Tundra Wing Vortex Generator

Wing Vortex Generators for the Durafly Tundra. Hobby King released the Grand Tundra with vortex generators on the top of the wing so I made these vortex generators for my regular Durafly Tundra.

Researching Vortex Generators I read several publications which stated the vortex should be between 12-15 degrees offset from the airflow. Not one publication had a solid formula for designing vortex generators. I decided on 12 degrees to reduce drag.

Heigth of 4mm of the VG was determined by taking a measurement of 1% of the wing chord (200mm x 1%=2mm) I added 2mm to that amount so the VG is crossing into the boundary layer.

Length of the VG was determined by Height x 3.8=Length (4mm x 3.8=15.2mm)

Distance from Leading End. Several publication state 7-16% from LE

Distance between VG. I read a publication which stated (Distance=10 x VG Height). D=10 x 4mm, D=40mm. Don't know if this publication is accurate.

How many to install. Some publications state to install fro
