Stab Repair "Help"

[Jim Ivey]

Larry
 I am glad this worked well for you. The fill work can be done with thin pieces of balsa wedges soaked with epoxy and trimmed before it can cure. Clean the fillet with alcohol also before it cures.
Now if someone can tell me how to repair a foam wing with a 5 inch trough 1/2 inch deep from the LE  almost to the tube,I'll be in business.If I can repair it It will be a spare wing panel.
