New airframe does not show up in QGC

Hello, I am trying to add a new custom airframe to use with my project. I have followed the steps in the documentation, for simplicity I copied the 15001_coax_heli file to 15002_custom_airframe and changed the @name and @maintainer fields leaving everything else the same. I also added the new file to the appropriate CMakeLists.txt file. However after uploading the new binary to my flight controller the new airframe does not show up in QGC under the Coaxial Helicopter group or anywhere else. Any help is appreciated.
