From the ones I listened to on this post,this is the one I like the best.It may not sound like the actual tanks mentioned here but it gives a real sound for the movement of the tank.This is one I would like to buy to add to one of my tanks.I think it is a killer set up. ...A $75.00 dollar cost seems fare enough for the sound you get.

But was wondering why two 9.6 batterys are required to make it operate........seems like a strange voltage being required to make it work..???? What is the actual voltage needed to make it work..???? MIN____MAX ????

I will consider buying one of these if the instalation is as easy as it sounds to hook one up ........

P.S. What ever that thumping sounding one was it don't sound like something I would expect to hear in a heavy piece of equipment.Mabe it sounds better inside a closed hull......?????
