Is the "soft cutoff" on Phoenix controllers really soft ? Does it give enough time to maneuver and land the heli safely or does it drop the power below hover point and the landing resembles autorotation ?

Currently I fly with a timer on the radio but occasionally I forget to start/stop the timer and want to use ESC to determine landing time that is safe for lipos but I do not want the heli drop from the sky. I know there are various lipo warning gizmos but if ESC does cutoff right this is all I need.

I have a CC25 ESC and when the soft-cutoff kicks in, the heli just drops to the ground. I've sinced lowered my lvc and am using a lipo warning device.

The cuoff isn't very pretty! It pulses and the heli is fairly hard to control. Just hover it a couple feet off the ground and let it kick in so you can see for yourself. I also have cutoff at 7.2v, but am using lipo alarm( If you look in my gallery it is on rear part of frame / round ) that is set to start at 9.4v.

msg73,
This is exactly my concern. We should probably ask CC to add "very soft cutoff" mode where it gradually lowers the throttle for a period of 2 min or so.
BTW where in NJ do you fly ? I live in Bedminster (Central Jersey) and looking for a place to fly.

Very soft cutoff would be good too, but my $10 lipo warning device works fine.

I live in northern NJ (near GW Bridge). I fly at a local park or empty parking lot on weekends. There's a huge soccer/baseball field about 1/4 mile from my work (Princeton) . I usually fly there during the week.

I usually land when I start to fell power falling off well before the cutoff. Cutoffs get REAL UGLY, real quick. I started off with Like90's warning device, but soon learned when to land by feel and took it off to save weight. Want to buy it?

Don't come off the throttle untill you see your GOD!

Thanks, that is what I suspected. Ordered battsignal and will set ESC cutoff below normal 3V/cell.
BlakeMcBrayer - thanks for the offer, I've ordered one before your reply.
