Folding Props vs Standard props

I am building an Introduction F5J from Hoellein and since I am looking into different motors I could use. I was wondering to what type propeller the Aeronauts are closest to?

Graupner folding, to some degree.

Unless you want the equivalent in a non-folding. Then we would need to know the motor being used, the voltage, the plane and its weight, etc.

One 10x6 is not like the next 10x6, folding or otherwise. Manufacturing differences and design are two reasons so it is tough to give an accurate comparison without know other data.

I am just looking for a rough starting point because none of the motor manufacturers ever show folding prop data.
Plane will be 35oz ~3m and I am looking to use a cobra 2213-26 or -22.

The charts for regular props are fairly close to what you will see for folders. Of course, it is not a 1 to 1 comparison.

eCalc does show the 2213-26 motor and you can plug in the folding prop data and see what the specs are.

here is a link for the Cobra prop specs for comparison ....
