Replace a brushed motor with a Resistor (+ Diode)?
the motors are inductive with series R but also generate  back EMF Voltage rising with RPM until prop with wind loading draws more current, so impedance at full load is 6.5V/1A= 6.5Ω equivalent, but nonlinear.

Nonlinear Z

DCR of motor may be &lt; 1Ω so if full throttle is applied at idle, the surge current may be as much as >6.5V/1Ω = 6.5A and reduces to 1A proportional to RPM which depends on ESC, prop load , weight , climb rate, so Amps will increase, with these factors.  

Normally series R to drop 75 mV max senses output current for feedback.
