It all looks a bit messy at the moment but my compressed gass effect and raising aerial radar are now both working. The gass is expelled when the top utility arm opens fully, triggered by a switch. It fires out through the open arm door and looks great. At £10 a can all I need to do now is not demo it to much. I am really pleased with this and it is a great crowd pleaser.The raising radar out of the thop of the head also works well. It is simply an electric car aerial that has been modified, a few bits added and a few LED's and it looks the part.
