Hi guys,

I know this has been asked hundreds of times before (maybe more...lol) but my search didn't exactly pop it up right away. Anyway here it is:

I'm trying to setup my Hornet CP and I'm looking over the programming for the CC Phoenix 25. Some are pretty basic but some are somewhat not. Here is my current setup:

Hornet CP
Electron 6
CSM200LW gyro
3 HS55's and 1 TowerPro 90 for tail
3S TP 1350mah
Feigao (1308413L) 4462 RPM/v ... 10T gear

I'm trying to figure out the best options for the programming. And, I'm still a newbee but I would like to try 3D manuevers with this heli.

Here is the programming list. I'll indicate the basic ones that I know would be the proper setup and hopefully you can direct me to the proper setup for the others:

1) Cutoff voltage = Option 5: 9.0V 12-16 cell NiMH or 3 cell Lithium packs
Option 1: 4.0V 2-4 cell Lithium Polymer packs
Option 2: 5.0V* 4-7 cell NiCad or NiMH packs
Option 3: 6.0V 6-8 cell NiCad or NiMH packs
Option 4: 7.2V 9-12 cell NiCad or NiMH packs, or 2 cell Lithium packs
Option 5: 9.0V 12-16 cell NiMH or 3 cell Lithium packs
Option 6: 12.0V 16 cell Nicad packs, or 4 cell Lithium packs

2) Current Limiting =
Option 1: Very sensitive (Very low over-current threshold, will rapidly shut-down)
Option 2: Sensitive (Low over-current threshold, will rapidly shut-down)
Option 3: Standard * (Moderate over-current threshold, will shut down after a slight delay)
Option 4: Insensitive (High over-current threshold, will shut down after a slight delay)
Option 5: Over current disabled (Over current detection disabled)

3) Brake Type = Option 5: Brake Disabled Helicopters
Option 1: Soft delayed brake * General aircraft use, with fixed or folding prop
Option 2: Hard delayed brake Direct drive applications where more braking power is required
Option 3: Soft brake, no delay Competition use where a very short brake delay is required
Option 4: Hard brake, no delay Competition use where a very short brake delay is required
Option 5: Brake Disabled Helicopters

4) Throttle Type =
Option 1: Auto Calibrating throttle* Recommended for general aircraft
Option 3: Governor Mode – Low RPM Range (see Note below) Recommended for collective pitch helicopters
Option 2: Fixed throttle Fixed pitch helicopters
Option 4: Governor Mode – High RPM Range (see Note below) Recommended for collective pitch helicopters

5) Timing Advance =
Option 1: High advance timing (12-35) Recommended for higher pole count motors (eg. Jeti or large Mega motors) Gives more power at the expense of efficiency
Option 2: Standard advance timing (5-20) * Recommended for most motors (Aveox, Hacker, Astro, smaller Mega, Kontronik) Gives a good balance of power and efficiency
Option 3: Low advance timing (0-15) Recommended for use when efficiency or run-time is primary concern – Gives a slight loss of power with a slight increase in efficiency.

6) Cutoff Type =
Option 1: Hard Cutoff * (Immediate motor shutdown)
Option 2: Soft Cutoff (Throttle down at low voltage or over-current)

7) Soft Start = Option 2: Soft Start* Recommended for most setups; governor mode soft start, slow spool up
Option 1: Very soft start Recommended for use with fragile gearboxes; governor mode slowest spool up softest start
Option 2: Soft Start* Recommended for most setups; governor mode soft start, slow spool up
Option 3: Fast start Recommended for fastest startup; governor mode faster start, fast spool up

The rest I figure I'd go on the default but maybe not. Any help would be great. Thanks in advance.

I've never used a CC in a CP yet but if I did...

1) Cutoff voltage = Option 5: 9.0V 12-16 cell NiMH or 3 cell Lithium packs
Option 1: 4.0V 2-4 cell Lithium Polymer packs
Cutoff's are not desirable on a heli!

2) Current Limiting =
Option 3: Standard * (Moderate over-current threshold, will shut down after a slight delay)

3) Brake Type = Option 5: Brake Disabled Helicopters
Option 5: Brake Disabled Helicopters

4) Throttle Type =
Option 1: Auto Calibrating throttle* Recommended for general aircraft
Not sure, I would probably tune the ATV range to suit the Fixed throttle (red LED on at 100%) or use the auto calib mode. Both using standard Throttle pitch curves. Then later have a play with the Gov modes to see if they perform any better.

5) Timing Advance =
Option 2: Standard advance timing (5-20) * Recommended for most motors (Aveox, Hacker, Astro, smaller Mega, Kontronik)
May be play with this setting in the future...

6) Cutoff Type =
Option 2: Soft Cutoff (Throttle down at low voltage or over-current)

7) Soft Start = Option 2: Soft Start* Recommended for most setups; governor mode soft start, slow spool up
Option 1: Very soft start Recommended for use with fragile gearboxes; governor mode slowest spool up softest start

Hornet X 3D Twister(Axi 208/20, Tsunami), MS-116 ESC, MS-044 gyro, KOK Extréme white blades, 3xTP1320 prolites ~15mins, AUW=375g. Futaba7C

Thanks Dark...

So far I set it as per your recommedation with the exception of the Cutoff Voltage which I set at the 9.0v cut-off for 3S lipos.... I think that's the only batt type I'm gonna use (and the only type so far which will work with the CP since my 2S lipos couldn't even get the heli to lift more than a foot off the ground..... and the batt cost more than the heli [bought used]...lol). I tried it out and hovered maybe 2-3 feet max in my living room... worked great... lots of power. It seems so cramp in the canopy though... but what the hell... I'll see for now, but maybe re-arrange the electronics later. Thanks again dark.

Hornet mrk1 was smaller... The later Hornet's fly best when setup correctly with 3 cell packs in the range 700-1500mAh. Most currently prefer 3xTP1320mAh Prolite packs (85g / 3oz) capable of 10C discharge or better. This will give you a flying weight between 340g (12oz) - 370g (13oz).

I wouldn't use a cutoff voltage (set to lowest value), say for example you have a close call and come down too fast, hit the throttle hard and the cell voltage drops under load momenteraly below 9v. The ESC will shut down in flight and you will crash.
Better to remove all cutoffs and use a low voltage warning device.
