Hey Chris. Since you do the cutting yourself have you ever had a problem with the spinner being unbalanced? Seems like it would be pretty hard to get the cutouts perfect. As far as I know there is no good way to check the balance on one of them other than to put it on the plane and check for vibration (which is an incorrect science in itself).

I have the TruTurn 2.25" spinner on my YS91FZ. I have used both the APC 15x6 and the APC 16x6 in it. You have to cut the slots bigger but otherwise it is working fine. I used a dremel tool with a cutoff wheel to enlarge the slots. The two nuts come close to the end of the spinner but its working fine (I can't remember, but I may be using the Dave Brown spinner adapter - one of them is shorter than the other) I have lots of flights on it now. I have also used it with an APC 16x8 propellor (temporarily had a YS120 on the plane) which is why the cutouts are a little bigger than needed.
