I've been testing the various new control-line modes on my test stand, using a Phoenix 35A ESC and (1) a Rimfire 35-30-950kV motor and (2) an Axi 2814/10.
The new "simple" C/L mode: (using defaults: Low Governor Gain, Medium initial spool-up rate, Medium Head Speed Change Rate; Motor Start: Medium, Timing: Normal; PWN Rate: 12 kHz). The Rimfire gave 9,000 to 11,000 RPM between about 1.65 and 1.80 ms while the Axi required pulse widths between about 1.47 and 1.62 ms -- so they aren't compatible with the previous Heli/High RPM/Governor mode.
The new C/L, Governor High mode: Gave the same calibration as before for the Governor High mode (about 1.3 to 1.43 ms to get 9,000 to 11,000 RPM).-- for BOTH motors.
The new C/L "Set RPM" mode: I set it up for the Axi motor, I thought, asking for 2000 RPM below 50% throttle, for 8500 RPM between 50% and 99% throttle, and 9500 RPM for throttle greater than 99%. The first run showed beautifully stable RPMs: from 1.12 ms to 1.50 ms it was 1710/1740 RPM on my tach; from 1.51 ms to 1.88 ms or so, it was 7260/7290 RPM on my tach; at greater pulse widths it was 8130 RPM. These were about 86% low, so I changed the number of poles from 12 to 14 and got: 2010, 8560/8490, and 9450 RPM!!
This mode would allow a real nice, slow idle, a slightly reduced RPM for level laps, and maximum RPM for the rest of the flight, for example. Cute!
