Hey Marty Thanks for the photo!
I really hate to have to put these on as they don't belong on the Goshawk, so I think I will have them laser cut out of clear polycarbonate, that way you'll never see them on a flyby
I downloaded the manual and found the reference
Additional Fences and covers
Your Hawk kit includes various parts cut from a color coded glass sheet. The wing
fences are an important feature on the Hawk. The glass fibre fences are fitted to the
wing leading edge just outboard of the aileron/flap break line. If you project a line
forward from the aileron inner edge there is a rectangular panel approximately 12mm
wide and 60mm long marked 45mm back from the leading edge. The wing fence is
mounted centrally on this panel using thick CA or epoxy.
Another feature of the Hawk are the fuselage fins mounted either side of where the
airbrake would be positioned. Two parallel lines are marked on the fuselage making
installation easy. The fins are given additional support by cutting two slots to accept the
location lugs. The fins should be firmly fixed using epoxy. The fins should be fixed with
an angle of approx 115 degrees on the inside edge.
