Default RE: RC motors speed/torque and acceleration characteristics

1. torque is proportional to current(A)- measure current at load and multiply by motor torque constant.
2. see above- maximum current (in this instance provided by manufacturer, 140A) coincides with peak torque. for BLDC, this is 0 rpm.
3. ESC settings vary by manufacturer

to be honest- the manufacturer just took the max voltage and a suggested max current draw, multiplied them, and gave that as maximum power. it is common for turnigy to do that. i think youll find real numbers significantly different than the suggested specs.
