Product Review (submitted on February 10, 2016):

I have quite a few of these, some I use as purchased, but most I rewind to my specs.
I notice that some complain about bent shafts..I have yet to bend one. The problem can be highly minimized by cutting the shaft. Mounting the prop adapter on the long shaft gives it too much leverage. Shaft should be cut just long enough for the prop adapter. Use only as much shaft as required..whether using a prop adapter or prop saver.
Another mod I do is I drill two extra holes for grub screws and tap them to 6-32. Sometimes I re-tap the existing grub screw holes to 6-32 also. It's much easier for me to find 6-32 tap and drill sets and 6-32 set screws than metric. Boxes of 50 set screws for less than $6. I still use Loctite on the screws. Of course, if you already have a metric tap and drill set to match exiting holes then just drill and tap two extra holes.
Another benefit is that not as much force is required on the grub screws and reduces the possibility of distorting the bearing tube.
