XNOVA XTS 4525-530kv 10P mit Ø 6mm Länge 56mm Welle
Designed for extrem 3D 600-710mm blade size helicopter where highest power to weight ratio is important.
It is a extreme power plant specially developed for the new Logo 700 helicopter.
It is a insane powerhouse and also a very efficient and cool runnning option for any other 700 light setup competition machine.

SC 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.
