Thanks to all that have replied so far. I just grabbed the spinner and wanted to see just how much wider I needed to make it. It appears that the spinner simply won't take that wide a prop. See picture.
In order for me to widen the spinner, I'd need to take out the guides that fit into the backplate. Presumably a bad idea.
So for now, I'd like to stay with the spinner concept - personal taste, I guess. So additional questions:
1) Do I purchse a larger diameter Spinner? I currently have a 2" Dubro (

2) How big a spinner can I get for a OS .46 FX?
3) Is this something you "just know" with experience? What rules of thumb are there so I can avoid this in the future?
4) Isn't a True Turn (or equivalent) too heavy for a .46? (mentioned here:
http://www2.towerhobbies.com/cgi-bin...?&I=LXFBJ5&P=7 ). What is the adapter kit needed for?
Sorry for the newb questions... I really thought I had a decent grasp of this hobby.
Thanks!

I would think cutting out the guides would not be ideal. My thoughts on the questions:
1. That’s what I’d do since you want to stick with a spinner. If you can find them, SIG nylon spinners are advertised as having “slots for APC props” (whatever that actually means).
2. The spinner size is dictated by the plane rather than the engine. Just go as big as you can without it looking “too big.” I would think 2.75 inches would still look fine on most of the trainer planes I have seen.
3. It’s really just what looks good. On planes with cowls the spinner size is determined by the cowl size
4. Tru-Turn spinners are surprisingly light. The adapter kit has a special nut to accept the retaining bolt for the spinner cone. Your Dubro has multiple screws around the outside to hold the cone on. The aluminum spinners use a single bolt in the tip of the cone and it screws into the adapter nut.
Even though I’ve been on RCU for a few years, I’m still very much a beginner and have lots of questions. I answer as many as I can but I still have more questions than answers. The forums really are a good resource so keep asking questions.
