As some of you may know, I purchased a heng long tiger 1 with the 2.4 ghz system in it. Until recently, I've had no problems with it. However a few days ago, when I was browsing the forum, I saw mention of the variable soundset and, sure enough, there were two little buttons on the controller, which were supposed to change the sound. So. I fired up the tank ran it around and then tried to change the sound. I first pressed the button on the right........ Nothing happened, but that's ok as I'm probably already on that soundset. Pressed the button on the left...........and instead of leopard sounds, the machine gun started firing

Thanks
