Battery Voltage - You will be able to see the voltage state of your battery during flight and respond appropriately to deteriorating conditions or alarms you’ve programmed in your radio.
Battery Current - Compatible controllers will transmit the instantaneous current draw of the system. You can use this information to reduce the load to prevent an overcurrent shutdown
Motor Power Output - This is the percentage of full power your ESC is delivering to your motor
RPM - Ensure you are within acceptable parameters, without the use of a tachometer
BEC Voltage - Monitor your BEC voltage and its stability to the RX even under different loads from different servos
ESC temperature monitoring can eliminate a potential thermal shut down
Battery - Ripple Just how hard are the capacitors, FETS, and internal components working with your set up, excessive ripple can cause internal heating of batteries. Excessive heat is harmful to the components and it can ultimately kill the controller
