It arrived sooner than expected and is what was described. However, it is kind of long for both of my older T-Rex 450 helicopters. I was just hoping it would fit. It is hard to find compatible parts for these because the manuals don`t give you the part numbers and there are so many models. So just in case others want to know, this rod length is aprox. 14 and 13/16 inches or aprox. 377mm. Good seller that I would buy from again.
