Hello,

I'm modeling a twin-electric-ducted-fan plane in Phoenix Builder. I'm building this virtual model to try to predict the performance of the actual scale model that I plan to build.

I've been using small-diameter, ten-blade propellers with 50,000 RPM and blade pitch based on a 45-degree angle at the tip. These specs are based on the 64mm fan/motor combos that I'm thinking of using in the actual model.

Someone mentioned that perhaps it would be more accurate to use turbines set at the published thrust of the EDFs. Or perhaps somewhat lower, since published specs often are optimistic.


Any thoughts on which method would give a more accurate performance: fan-sized propeller blades or small-thrust turbines?

Thanks, Bill
