This item was purchased new at a store. I don't remember the exact purchase date, but it was about a year after I bought this that the MT-5 was released, so it's close to the final model. It has never been dropped, but I once fell while holding the transmitter. I tried to protect the transmitter from impact, but there are some scratches from that incident. The usage time is 142 hours, which I think is low considering the age. I reset the model, but please forgive any oversights. The power supply is the original LiPo specification, and the original battery box is not included. The original box, inner box, red plastic bag, instruction manual, and stickers are included, but there are no other small accessories. This is a used transmitter, so please refrain from purchasing if you are overly concerned about its condition. I look forward to your consideration. MT-S M12S M17
