Of all the time i've been working on single & multi rotor copters, I've never once had to program my ESC's. I've always been lucky enough to have them work out of the box. I think that luck has ended though and I need some help wrapping my head around this.
I'm flying an x650 frame with 4 Avroto motors, DYS (hobbywing) 30amp esc's & 11x5 graupner props. When I switched to the 11 inch props I started getting some strange pulsing on the throttle. It's been suggested a couple times now that I change the esc programing, so that's my next step.
Anyone have any advice on settings for that combo of gear? Below is a list of all the programable settings in the ESC.
Thanks in advance!

Programmable Items:
1. Brake Setting£ºEnabled / Disabled, default is Disabled
2. Battery Type£ºLi-xx(Li-ion or Li-poly) / Ni-xx(NiMH or NiCd)£¬default is Li-xx.
3. Low Voltage Protection Mode(Cut-Off Mode)£º Soft Cut-Off (Gradually reduce the output power) or Cut-Off (Immediately stop the output power). Default is Soft Cut-Off.
4. Low Voltage Protection Threshold(Cut-Off Threshold)£ºLow / Medium / High, default is Medium.
1) For lithium batteries, the number of battery cells is calculated automatically. Low / medium / high cutoff voltage for each cell is: 2.6V/2.85V/3.1V. For example: For a 3 cells lithium pack, when ¡°Medium¡± cutoff threshold is set, the cut-off voltage will be: 2.85*3=8.55V.
2) For nickel batteries, low / medium / high cutoff voltages are 0%/45%/60% of the startup voltage (i.e. the initial voltage of battery pack), and 0% means the low voltage cut-off function is disabled. For example: For a 10 cells NiMH battery, fully charged voltage is 1.44*6=8.64V, when ¡°Medium¡± cut-off threshold is set, the cut-off voltage will be:8.64*50%=4.3V¡£
5. Startup Mode£ºNormal /Soft /Super-Soft, default is Normal.
Normal is preferred for fixed-wing aircraft. Soft or Super-soft are preferred for helicopters. The initial acceleration of the Soft and Super-Soft modes are slower in comparison, usually taking 1 second for Soft startup or 2 seconds for Super-Soft startup from initial throttle advance to full throttle. If the throttle is closed (throttle stick moved to bottom) and opened again (throttle stick moved to top) within 3 seconds of the initial startup, the restart-up will be temporarily changed to normal mode to get rid of the chances of a crash caused by slow throttle response. This special design is very suitable for aerobatic flight when quick throttle response is needed.
6. Timing£ºLow / Medium / High, default is Low.
Usually, low timing value can be used for most motors. We recommend the Low timing value for 2 poles motor and Medium timing value for motors with more than 6 poles to get a high efficiency. For higher speed, High timing value can be chosen.
