The autorotation gear can sometimes be damaged when the red torque tube gears strip out. Goo to have a spare -- comes with nothing but the gear and sleeve.

tail drive gear
I put it on my 600, the t count is a bit lower although it holds very well. feels more powerful. It is a good replacement along with the front and rear gear set. Advisable to replace them all whilst your there.

Must have
This is a must-have if you're running 550e. Especially if you have the older style gears with smaller teeth. Keep a few of these on hand in case you crash, it's one of the first drive line items to strip. An absolute necessary upgrade from the older style gear, I've stripped the old style gear in flight several times.
