RE: m1a1 abrams
Hi
I had one of these and quickly got rid of it. It was single speed, rubber band tracks, gun elevation always made the machine gun go. It looked OKish but the finish on my one was way overdone and did not look realistic. Several folks on the site were upgrading them to HL electronics and tracks but I did not bother as I am sure one day one of the other manufacturers will bring out something better - plus money went towards my new HL Jagdpanther.
cheers
