Got a new wing from Horizon the other day. If I were to line up the root ribs on each wing half and glue them together the new wing would be exactly like my old wing....ie.. the leading edges would line up correctly and the trailing edges would be 3/8" out of alignment. the left half wing tailing edge is higher than the right half wing trailing edge...thereby causing the right half to stall WAY before the left wing. If you line up the trailing edges the root ribs are very uneven. Horizons response to my question to them was....send it back at your expense and we will send you another one at your expense....hmmmmm........go figure...
