Hello rcflyer227,
Sorry to hear your tank showed up in non-running condition.Even if it was running,at best their controls are not very good
and most make a lot of crunching sounds when you run them.They can be made into a pretty fair tank with a major up-grade using HL guts and controls.They are one of the few if not the only cheap 1/12 scale hulls you can find for the price to work with.
You didn't specify what type 1/6 scale model tank you was looking for,but you can't go wrong for the money with a 21st.century
M5 Stuart as a well made starter tank in that scale.I have four of them and there are quit a few other's here on the forum who have them.A very good source for info on them is (DAP a member here) who has them and worked with them.Watch the classifieds here on the forum,buy from a member,or they sell all the time on Ebay.When you buy one I guess you just have to trust that you will get one in working order from the seller,however I know this is hard to do especially if you have been burned in the past.Price would run around $120.00 to $170.00 for a good used one.Shipping can be in the 50 to 60 dollar bracket for transporting half way across the good old USA.-If they want much over that I would steer clear of them-
Hope this helps you out.-BIGMIG

P.S. Mine are not for sale-
