F15 flaps commnds not updating aircraft state

[jamesonyee]

I'm working with the FDM using blueprints, and I am able to convert controller input into flight commands that change the aircraft state for pitch, roll, and yaw. However, when I try to update the flaps, it reads the flaps are down, but it doesn't update the aircraft state. Any ideas as to why this might be happening? I attached a video and screenshot of the blueprints below.

The flight model for the included F15 doesn't have flaps. You could search some of the other aircrafts and see how they have added flaps, then incorporate them into the f15.xml

Thanks for the help. got some basic trailing edge flap properties going with data similar to trailing edge flaps on the f16.
