F-111  Step #5 Test Fit

 
Prev Step #4   Next Step #6

First be sure the area along the center line of the Center Plates is clean and free of any extra glue. Sand and fit the wings using the 1/32 pilot hole. The wings must move easily forward and backward.

Once everything is a-lined, move the wings to the sweep back position and pin the wing in 3 places to prevent it from moving. Drill a 1/4 in hole through the top plate, wing and bottom plate. Use scrap balsa and a sharp drill bit to prevent any chipping of the balsa from the drill. For now use extra long 1/4 dowels to make it easier to remove and check fit.

Point A is the wing stop.

  Sand clean and fit wings, any glue along the center line
 will cause wings to stick
