ESC Settings

Xnova XTS motors are not picky about ESC settings.  Most default settings are just  fine, but there are some things to consider.

Xnova XTS motors make best power with low timing. You may want to set timing at around 5 to maintain power and efficiency, then play with PWM to adjust temperature of ESC and motor. As you already found out the ESC gets warmer as you increase the frequency while the motor gets cooler, and vice versa.

Heli specific setup:
Governor setup is critical for a constant headspeed.  Too low a throttle setpoint  will overstress the entire power system.  Pulling 100A at 50% duty cycle on the  esc produces very high current ripple and high peak currents in the system.  This  reduces efficiency a great deal.  Also remember that 50% throttle on the  transmitter may or may not be 50% throttle (duty cycle) in the ESC.  These values  may not be directly related.

For a 3D heli setup, the gearing, motor kv, and headspeed should be chosen so that at the highest power draw the ESC still has some "headroom" to operate.
