Good quality spinner and bracket. I especially like the thin bracket that acts as a spring and holds the spinner tight. Ive been through several of the other kind with a stiff, rigid bracket. They are always a problem. The last one even cracked off and the bracket scraped up the full length of my prop as it departed. Not this one. It has a well designed bracket that tightens down and holds tension when you tighten the screw. No more loose screws, cracked screw holes, loctite, spinner wear on the prop hub, spinners flying off, broken brackets, nicked and scraped propellers, all things of my past. Its almost like the manufacturers knew what they were doing when they made this bracket flexible and springy, and got PMA approval.

Considering that the alternative is close to $2K, this is a great solution. The mounting bracket could stand to be a bit thicker as it does twist under the 30Ft/lb of torque required of the prop bolts. A box wrench will hold the counter force needed to make it work tho. A little polish and paint before assembly and she lools great!

Nice product but the bracket is too soft. I did not have a choice to use plier to keep it untwisted/ straight when I torqued prop bolts. The lock nut doing his job to keep the cap screw there.

For a more more aesthetic part it would be nice if it had less scratch marks in the aluminium.

Mount bracket is so thin that it twisted and deformed when the prop bolts were torqued to specification. Terrible engineering done on this mount bracket, and its FAA/PMA. Really?? Found a used older bracket that was twice as thick to use. Stamped UNIVAIR all over it. Dont waste your time or money. Spinner is fine, no problems there.
