Problem with CC45 and AXI2820/10

I have a new AXI2820/10 and CC-Phoenix45 that keeps cutting out at very low rpm.

When you start applying throttle the motor spools up and according to the whatt meter gets to around 45-50 watts and then cuts out. Vlotage at cutout is approx 11.8v and amps is approx 4amps.

The following is my setup

Prop 11x6 folding prop (MPJet 40mm spinner and graupner cam blades)
Battery 3S2P 2600 Polyquest

The settings I have programmed the C45 with are as follows;
Cutoff voltage 9.0v (option5)
Current Limiting standard (option3)
Brake soft delayed (option1)
Throttle auto calibrating (option1)
Electronic Timing Advance Standard (option2)
Cutoff Type Hard (option1)
Soft Start (option2)
PWM Switching 11kHz (option1)

Any suggestions as to what might be wrong would be greatly appreciated.

You could lower the cutoff voltage (just for testing and while you are closely monitoring the voltage) or select soft cutoff to see if it is the LVC that kicks in.

What happens without prop?

Didn't have any luck with solving this problem by changing settings, looks like it was a LVC problem.
I ended up purchasing the Phx Link and updating the software in the controller which fixed the problem.
Shame to have to spend extra dollars to fix the problem but i guess no I have it I can make the most of my CC controllers by keeping them all up to date.

It is also nice to be able to look at your settings on a computer screen instead of listening to beeps!
