I am building a Tiger-60 that has a 4 stroke Thunder Tiger 91-S in it. I plan to build a cowl around the engine and put a 3 blade prop with an aluminum spinner on it.
I have been looking at a couple different sites with spinners and I have just been getting confused. I'm not sure which spinner to get and what size and not sure if it will need an adapter or anything on it.

Help please?

I would say any engine (especially four strokes) over the .82 cubic inch displacement should have an aluminum spinner. You might check Tru-Turn. I have two of their spinners and love them, one of which I had made to order. Spinner size? Whatever looks good.

Aluminum spinners need to have an adapter nut. You will need a 5/16 x 24 "long" adapter nut most likely. Tower hobbies sells about any size tru-turn 3-blade props. You will most likely have to grind on it some to get your props to fit( I always do). For some reason all my aluminum spinner needs a spacer washer on top of the prop washer because the adapter only screws on so far,so watch for that.

I was thinking a 2 3/4" or a 3" spinner.
Can anyone show me a link to which one I should buy and what adapter is needed? Also...any prop suggestions?
