Gmax for FS2004 Flaps Problem

OK
In Gmax I am creating an aircraft model. Everything was going well animation-wise but I have a problem with the flaps. I have named the flap parts R_Flap and L_Flap and when I export them to FS2004 they move, but in the wrong direction - eg fully extending the flaps extends them upwards not down as I would wish. I have ensured the pivots are at the front of the flaps.
Any ideas
