Can you help me?

G'day Stas
For a 91 fx the size 2.25" or 2.50" spinner should be fine.

And i ask for it so?
Plz give me an aluminum spinner of this size?
Also from Tower Hobbies can i find one?

The spinner size depends more on the plane, than just on the engine size. For
instance, this P-51 mustang calls for a .46 size engine, but uses a huge spinner.

This Cessna 182 has a big .91 four stroke in it, but uses a tiny spinner.

And US Navy warbirds with radial engine, such as the Corsair, Wildcat, Hellcat, and Bearcat, use only prop hub.

Yes a prop hub but with what dimensions?
Because i cann't write a mail to tower to tell you that i just want a prop hub for my OS 91 FX.

Also, the spinner size depends on the size of the plane. For instance, a .40 size 58" span P-51 Mustang calls for a smaller spinner than a .90 size 71" span P-51 Mustang.
