Blade Element Momentum theory program to calculate small-scale low-Re rotor characteristics. The current implementation is useful for multirotors.

Not bad for the first time.

The comparation with CFX and Russian CFD package LOGOS from

Vladimirova, N.A., CFD ANALYSIS AND CALCULATION OF AERODYNAMIC CHARACTERISTICS OF HELICOPTER ROTOR, ERF 2013.

Very simple, very reliable impulse theory applied to small scale rotors, quad's alike, seems to be very promising.

Espesially at low velocities.

The data about propeller were obtained in thesis Isa Diana de Sousa Baptista Morais Carvalho "Low Reynolds Propellers for Increased Quadcopters Endurance",
the experimental data scrached from http://m-selig.ae.illinois.edu/props/propDB.html

Sure, it can be more precise but i've only used classical work...
