I assume most of the n50 motors are 3.7v as on my S033gg. Since the "conversion", I upgraded the short n50 for a long one that was a Main motor for a 8inch coax, but still need resistors to keep the 7.4v ESC from killing the tail motor. I'll probably end up installing g a 5v regulator and running ESC at minimum voltage.
