I have just merged two planes and everything is now working good, but the one remaining problem is when flaps 5 is selected on the 737 the slats come out all the way, they should not come out fully until flaps 10 is selected to my knowledge. It is really not a big problem, but just soemthing that would be nice to have working. So my question is what would need to be modified, the aircraft cfg, the .mdl file?

Nevermind, figured it out myself and now I've got a fully working merge between the ariane 737-400 and the Feelthere 737-400.
