Long Tube Top for DIY Helicopter Collective

In Gazmac52's assembly videos he says to glue the "Tube Top" onto the end of the aluminium tube. While his design is generally very well thought out the concept of simply gluing this part in didn't sit well with me, so I redesigned the part such that it can be "bolted" rather than "glued" in. The length of the part had to be extended to be at least as long as the throttle grip such that a 3mm bolt could be used on the underside of the tube to hold the piece in place. I also reduced the diameter of the piece a little so that it could be inserted without needing to sand it down. I tried diameters of 22.5, 22.6, 22.7 and 22.8 mm and found that 22.7 mm slid in nicely without modification, so that's what I've uploaded. Enjoy: 🙂
