Default E-flite esc?

I received an eflite 40 amp esc for Christmas. Enclosed info is not very clear about soft start and or if the low volt cutoff is soft. I'm thinking about using this esc in a 450sa i'm working on. Any info or experience with this esc would be appreciated. Thanks.

I have a 20-amp version of the same unit, I like mine (BCPP with Hacker e3-49 4900kV).
The start is nice and soft, the softcut is pretty quick though, as soon as you notice power loss you had better land.

What's 'softcut', and how does it work?

When the esc senses that the battery voltage has dropped to some predetermined level, the esc will reduce power as a signal to the pilot that the batteries are about to be over-discharged. Typically this can be a reduction in power or a pulsation. There is supposed to be enough power left in the system to allow a safe landing (if you hurry) without over-discharging the battery, which can be damaging.

I've always wondered if one could fly the 450 with the eflite 370 brushless 4100kv motor...

Shaft diameter is different, the 450 pinions won't fit the shaft, on quick inspection the gear pitch is similar on my MX400 main gear as on the EFlite pinions, but I don't know about TRex gear pitch, I think it is different too.
