next,level across the top fuselage longerons and the canard spar cap.lastly(and most important),use your canard incidence blocks to accurately set the incidence at zero with the top longerons.the patterns for the incidence block is found on page A-13.If your canard has a silght twist,set the average incidence equal to the longerons.recheck sweep,dihedral ,and incidence and clamp firmly in position.use the #10 pilot holes in the canard tabs and drill #10 throungh the F22 bulkhead.go cut two tabs of high density foam (dark red)as show.
