Thank you philipat,
Was watching some of the youtube you refferenced,and some neat dozers there.I knew these were being rc'd and it was nice watching some in action.Just looked through 18 pages of tanks on ebay checking for size and prices.Wish i could see some of these models "hands on" as for me looking at a picture is hard to judge suitability for what i have in mind as to RC-ing it.May have to try some of the local toy stores,or just take a chance on what i end up with.
Thanks again.............BIGMIG
