I'd send it back, but prepare yourself for a slow return time and less than desirable service from my recent experience. I sent in four servos and an rx for service. Two of the servos only needed new gears as the ones they had were only stripped. The other two were just dead in the water. The rx was offered to me after it was involved in a minor crash. I figured I'd take it and have it checked out. They sent me an email listing the repairs telling me the servos were ALL trashed and were not worth repair,,ANY OF THEM. They offered me credit on the DEFECTIVE ones for new ones. They also stated the rx was not worth repairing, gezzzz, the crash wasn't bad at all. They did offer me credit on the rx as well about 10.00. The total price I was quoted was about $70.00 way too much I thought. I told them to just return the rx and I traded the 3004's for lesser 3001's to the tune of 40.00 plus 8.99 for shipping. Now, it's been over two weeks and I still have no servos. Rather slow on shipping I would say.
