I know plenty of reputable, well respected dealers who ship items they have personally tested only to have the customer respond to them the tank was broken, not working. These tanks really do not like being mishandled shipping wise. I could be cynical here, but are you telling me you didn't notice a 1" impact crack when you took the tank out of the box, installed the battery etc? Perhaps you didn't and I could understand that but then that is what Matomart might be thinking. Of course they will also be thinking the profit margin on these tanks is fairly low and the costs you are talking about would wipe those profits out completely. I know what you are feeling, I recently purchased a pair of King Tigers for around $450 US, one was DOA, with a broken controller, smoke oil leaked everywhere and both had broken exhausts. One that did work had a broken smoker and I originally thought both were broken but it turned out that one tank had mismatched crystals in it. Four months and I got my money back. The tanks being broken wasn't the retailers fault nor was the long delay faced waiting from them to supply parts (Matorro suck) but they could have fixed it in other ways. Try telling them you are returning it, claim the money back from the credit card company or Paypal are also options. Problem is RC vehicles and electrical spares are fragile and prone to rough use so suppliers are often hesitant about fixing problems. Added to this the large amount of fraud from customers wanting something for nothing and it makes life harder for people with legitimate issues.
