I have the 40, 45 and 80. But you are correct the 45 they had some problems with (the version 2 that is) and the version 1 they stopped selling for quite some time now.
But I fly with them on the 450's and 500 and never had an issue with them (aslong as programmed correct) and they have an fantastic soft start

I have never used the governor but that also seems to be quite good.
Goodluck with it
