Section 5: Mounting the Wing to the FuselageParts Needed• Wing• Fuselage• Wing hold down hardwareTools and Adhesives Needed• Hobby knife with #11 blade• 30-minute epoxy• Epoxy brush• Mixing stick• Rubbing alcohol• Felt-tipped pen or pencil• Pliers• Ruler• Drill• Drill bit, 1 /4”• Round fileStep 1. Locate the forward mounting bolt holes in the wing.Trim the covering from the mounting bolt holes with a sharphobby knifeStep 2. Place the wing onto the fuselage. Use care as the firstfew times the wing is inserted, the fit is snug. Note the tolerancebetween the wing and the fuselage. There is little movement ofthe wing once it is in the fuselage wing saddle area. You cancheck the alignment of the wing to the centerline of the fuselageby making a reference mark at the tail of the fuselage, thenmeasuring each wing tip to make sure the wing is aligned.Step 3. With the wing centered in the fuselage wing saddlearea, secure it with masking tape so it will not move from side toside. Measure from wing-tip to the center of the fuselage at therear. When you are satisfied with the alignment then proceed.Step 5. Use the holes in the top wing bolt plates at the trailingedge of the wing as a guide to drill two holes into the plywoodwing support at the rear of the hatch area in the fuselage. Again,drill at 90 degrees to the wing chord line.Step 6. Remove the wing from the fuselage. Trial fit the blindnuts into position under the fuselage plywood wing supports atthe front and back of the fuselage hatch opening. Use pliers withan adjustable opening to squeeze the blind nuts into position sothe “teeth” penetrate the wood and stay in place.Note: It is a good idea to place a piece of scrap wood on thetop side of the plywood wing hold down blocks whenpressing the blind nuts into place.EDGE 540EDGEUltra Aerobatic 1.20 ARF540Ultra Aerobatic 1.20 ARFStep 4.
