Hi Pete
There are many different converstion formula out there for changing the number of blades you are currently using.
But the simplest one that is pretty close to the money without breaking out the old slide rule will suggest the following
4 blade 10 x 6 =
3 blade 11 x 6 =
2 blade 11.5 x 6
The only difference is the more blades you have the less torque effect is generated on the airframe during take off when high rpm and low airspeed are present.
Hope this helps
