Brodak .40 Crankshaft Thread Length vs. Spinner

[Peter in Fairfax, VA]

So, I'm pretty happy with my Brodak .40 / Brodak Vector combo.  3-7/8 ounces of fuel, does the pattern.

However, the TT Thunder Tiger 11x4.5 prop is kinda thick and the crankshaft threads seem a little short.  Would like to mount a spinner, but concerned there is not enough room.

Thoughts?

make a McCoy type prop nut that go's into the prop .make it long enough to attach the spinner to it

Did you try the 10.5x4.5 apc?
