Hey guys, I already posted a topic discussing my upcoming landing panel, and now I have gotten much further on it (custom gauges, no more jacked up leaning). I just got one question. I fired up my test plane for it, engines on it were dead (thats how it was saved). I pressed J+ and held it, and  heard the engines winding up. However, there is no indication on the gauges the engines are starting and the attitude indicator just floats happily down. I can't figure it out, I have never had this problem before. Any help would be appreciated.

I had Concorde on a B737. Right now it's back to the default 737 stack though.
