1) The principle of RPM Standardization
Throttle value
100% +100%
During the RPM standardization, the ESC will establish a “Motor RPM-Throttle” curve by itself based on the actual battery voltage and the actual KV rating of the motor. Therefore ,
you need to standardize the speed with a fully charged battery, and ensure the main blade pitch is 0° (in order to make the helicopter not take off).
In general, people use the default “Throttle Curve & Pitch Curve” of the transmitter (as shown below) when they standardize the speed.
Attention! Please ensure the main blade pitch is 0° and the throttle amount is above 40% (we recommend using 50%) when standardizing the speed.
2) Procedures of RPM Standardization
• We recommend using the default “Throttle Curve & Pitch Curve”. ( If you don’t want to use the default setting, then please ensure the throttle amount is 50% and the main
blade pitch is 0° when the motor rotates.
• Turn on the transmitter, move the throttle stick to the bottom position and then wait for the ESC completing the self detection.
• If you’ve set the “throttle cut” function, please lock the “throttle cut”, and then move the throttle stick to the 50% position and then unlock the “throttle cut”. If there is no
“throttle cut”, then you can move the throttle stick to the 50% position directly.
• The ESC drives the motor to rotate, the main blades start to accelerate slowly (because the main blade pitch is 0°, so the helicopter won’t take off, but you still needs to be
careful), you need to wait for the acceleration completing and the speed getting stable, and then lock the “throttle cut” or move the throttle stick to the bottom position.
• The ESC will stop driving the motor, the main blades start to slow down and then stop rotating.
• The RPM standardization completes.
Attention! Please calibrate the throttle range before the RPM standardization. There will be no need if you’ve carried out the ESC/Radio Calibration when the first
time you used this the ESC or you didn’t restore the settings to factory defaults after the calibration (changing the transmitter & receiver is an exception).
