Advice on UAV for filming purposes

Hey fellas, I'm sure this will have a limited response, but I'm hoping someone can direct me to an Avsim equivalent forum that is specific to UAVs (Unmanned Aerial Vehicles) I have trawled a few on the Net, but I don't want to waste my time posting on some smaller forums but would rather hang around an 'Avsim equivalent' forum... hope that makes sense. My profession is TV cameraman and photographer, I run my own photography business and am currently researching the UAV market and need a platform so I can ask questions and seek answers. Any help in this area would be very much appreciated. Thanks.
