SITL Questions

Hello! I have a couple of questions about the Ardupilot SITL feature:

  1. Does it support hexacopter modeling? I’ve been able to run it as a quad and octacopter, but when I try to use a hexacopter frame it builds for a quad.
  2. I have ArduCopter 3.2.1 downloaded for my actual hexacopter, and I would like to test modified firmware. When I run the script, it builds ver 3.4, which is a developer version. How do I get it to build 3.2.1 (which is the directory I’m running it from)
  3. Where is there a list of the data available to graph in flight?
    Thanks in advance for the help.
