1. Shown is the current construction Play between pin and holes in tube is causing the tictac sound. Current Part TicTac Noise (CF#64)

2. MD has this idea for an alternative axle. It is same tube, but longer. It has flat surfaces to fit in boomerang. 2 flanged star nuts are inserted on both ends No modifications are needed for other parts. TicTac Noise Suggestion

3. Compared to current part Overall length and diameter: identical Less parts No change to plastic parts needed Note that M6 bolts for fixation to boomerang need to be 30mm longer than now. TicTac Noise Suggestion

4. Install star nuts as shown in video clip (on FTP server). (same technique as used for bicycle fork installation) Tool helps easy and correct insertion (fast, 30mm deep) TicTac Noise (CF#64) Star nut installation
