These heli servo horns have done great they break fairly easy in a prop strike much cheeper to replace these than the other moving parts bending or breaking!!!

Great OEM Replacement Part
These are small servo arms, which is exactly what came with my TB40 kit. It appears when you crash you break the arm rather than stripping a servo gear. A much cheaper option and easier repair to deal with.
