Hey Buddy !!! Happy New Year !!! I'll let you know what I get back from them. It really could be interesting. I read and re-read their web pages several times now and they state that their stuff has worked in tanks as heavy as 35Kgs. Isn't that about 70 pounds or so? I think I'm up to around 37 pounds so I've got a little left to go. It sure sounds promising though. Also, go to Elmod's page where you can download the WAV files and turn your volume up. Find the one for the M1 Abrams and let 'er' loose !!! Damn, that's loud !!! With a decent speaker, you really could wake up the neighborhood.
