Hi Luigi,

yes, you can use Drive Calculator for ducted fans, but until now there are
no constants in the database. If you have the equipment to do the
measurements, it is your chance to be the first to contribute the missing
data. You may use the built-in 'virtual dyno' to have power constants
computed. You will need a thrust stand to register thrust data and may use
the 'Generate' function to have the thrust constants computed.
