RE: Hone 450 (new all-metal 450 heli)
Here's a picture of my fix. I think it'll work just fine, it looks like it will. Gives a lot more room for the arm, being in the back holes and all. I used a 2mm x 25mm hex bolt, with a lock washer and regular 2mm nut holding the metal ball and pin. I'll let you know how it goes.
