Not really...the Sellers I've bought from usually will test the tank before sending it out...If not ..I usually ask them too...so far never had a problem with a New RTR...especially the T34....when that came out it still had the 1st Gen 2.4 rig...and even with that it had superb range
I wouldn't be sure about the sellers in the UK...but I would think they would have gave them a test run before sending...just to cover their tails
Certainly hope this is an isolated thing...as it could be they sent you returns from the Holidays
Now with that said....I wouldn't do anything else to them yet...contact your sellers ...and see if they will help you out..it's really a good way to find out how honest they are too
If you got them from EBAY...call EBAY direct...explain your problem ...I know here in the US...I was told by an EBAY rep..they will send you a mailing label so you don't have to pay for the return shipping..I've never had to do that yet though...as like I said...all my tanks arrived in great running order
