Hi, the default config does not include Expert and Nightmare. I was asked to make more skins for these from people so I added them for others to use. If you want them, you must add them to your config manually.
Also, because of the fairly complex nature of the config, and the fact that anyone can edit the heli profiles to be called whatever they want, I took the decision not to automatically add the Multi Heli Signals to people updating their plugin. It only adds those to people installing the plugin for the first time or with a fresh config. So again, you can create these or use the default config on the plugin page as a template to ad these to your own config.
The wave helis are working, so if they are not, its more than likely a config issue. If you upload your config here I can have a look for you.
