Master Airscrew propeller 11x7

MICHAEL  2 points - 3/21/2013

The majority of propellers used in the radio control flying hobby have two blades but props with three or even four blades are available. Two-bladed propellers are commonly used because they are relatively efficient and easy and cheap to produce but sometimes an rc airplane will call for more blades, particularly where a scale look is required. Adding more blades decreases the overall efficiency of the prop because each blade has to cut through more turbulent air from the preceding blade - in fact a single bladed propeller is the most efficient but these are rarely (almost never!) seen in our hobby although they have been experimented with. Incidentally a single bladed prop has to be balanced with a counterweight on the other side of the hub to the blade, otherwise the plane would shake itself to pieces as soon as the prop was turning! If choosing a three or four bladed propeller the general rule of thumb is to decrease the prop diameter by an inch and increase the pitch by an inch, but on some models fuselage and ground clearance issues might dictate which propeller size you can and can't have on the model. As with everything, trial and error... In which case you would be looking for an 11X9.

what is the equivalent 3 blade prop to a 12x8 2 blade prop ? Is there a chart somewhere ?

Are these ok for Electrics, or nitro/gas only?

I am looking at this Prop because it is available as a pusher as well. I am building my second hexacopter. i have used a couple different static thrust calculators but each gives me a different result. I would like to know if i can use this prop on a Turnigy L3010C-1300kv (420w) motor? i will also be using 50amp (60amp peak) speed controllers.
