[NSRCA-discussion] Need a little help with ICE HV80 setup

[Ed White]

OK. Pretty much case closed as far as I am concerned.  Changed current cutoff to 
insensitive and got two flights on the same battery packs that were surging 
before.  They sound just fine now..

I haven't looked at the logger data yet.  Not sure I will do anything different 
no matter what it says.  I think it was just seeing very short duration noise 
spikes

Thanks for the help,

Ed

 Hi Ed,

Change to insensitive and it will never happen again.  The way it     was 
explained to me was that the controller only needed to see 1     (millisecond?) 
of 100 and it shuts down where an insensitive setting     would require a 
sustained reading of 100 to shut down.  On a fast     throttle up it certainly 
is possible to get a little spike and     activate the cutoff. Your setup 
depending on the batteries should be     about 80-85 amps peak static.

Enjoy that plane!

Chris

In a new E-motion I've got a Pletty Xtra 30-10, ICE HV         80, 20.5x14 PT

for about 65 amps WOT.  According to         the logger I'm exceeding 100 amps 
in the air and triggering the         current cutoff.  I can hear the cutoff 
operate in the air.  But         I do not get an error code.  Firmware is the 
latest.          Settings.are below.
