The Raptor 50 comes with the Raptor 60 tail parts and the instructions DO NOT apply completely. The manual does not mention the set screw that goes into the tail shaft but it is a very important part. I know those who have Raptor 60s and it was a big deal with them that the set screw was left out and tails were failing.

The set screw goes into the shaft opposite the tail rotor. the set screw fits tightly against the pin itself to keep the pin from backing out.

Please check your tail setup for this screw because I do not think the pin by itself is enough.
