Got this to replace the original tube. This one has a BLACK end that goes into the Clamp Base. My old one has a WHITE end (like the picture HD has in the description) which fit fine. This one won't go in past an inch then binds up. I also bought a new Tail Tube Clamp Base. This won't fit in that either. Don't know if this is just a bad one or if all the BLACK end types are faulty. Not blaming HD but FlyWing should step up their QC.
