Scratch, my BCP tail shaft got to be so loose that it would twist in flight. This is no fun and so I placed the heli upside down with the tail pointing down a bit and then put small amount of super glue on both sides of the shaft where it meets the flat section of the main frame. I then (of course) allowed it to dry. Just make sure that you don't let any glue work its way into the shaft bore in the main frame. Also make sure that the boom is (of course) properly aligned before you glue it. Doing this secures the tail yet allows you to remove the boom if needed by carefully twisting it until the glue breaks.

Good luck and good flying!


P.S. I've been in this hobby for over 20 years and have only had three serious glitching problems with RTF radios (never w/ Futaba or Hitec). One problem was traced to a cracked solder joint on the Tx antenna connection to the circuit board and the the other two were traced to interference caused by the main fluorescent lighting in my garage.
