You're not nuts, its safer carving small props anyways.

4.5x2 is the standard.
4x2.5 is the speedier prop.

The little three blader is not worth looking at to most.

The other commercial decent alternative, for more sedate models, is the Graupner 5x2, it has the right prop hole too.

That gives you a good idea of suitable prop loads. TD or Pee Wee?

Cox once made a small 1/2A prop for their Camel that looked pretty cool. Interesting subject for carving I'd think in a 4.5x2-ish size.
