Very nice tank, believe it to be the early production 1955 type which I prefer much more than later versions 1960 or 1968 . Had a lot of fun playing about in the local park with it, Goes up hills and over grass without any bother, sounds of the engine and gun sound great . Heng Long are very accurate and precise with the details on there R/C tanks I feel than any other manufacturers of R/C tanks . Have bought a few tanks now from Hayaltd.com and the orders have always being very reasonably priced ( compared to other sellers ) and a fast delivery service 1 or 2 days. So now the Bulldog has all it's accessories on, tank commander painted, and I have weathered the tank slightly so it looks great now . Probably go for the Tiger 1 with steel tracks and wheels next as I have still have room for one more in my display cabinet and it would look good beside it's bigger brother the King Tiger. Thanks for tank Steve.
