Hi Ed,<br>
<br>
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.<br>
<br>
Enjoy that plane!<br>

font-size:10pt;">In a new E-motion I've got a Pletty Xtra 30-10, ICE HV
80, 20.5x14 PT models CF prop. The problem I have is that I
have it set on the ground 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. <br>
<br>
Should I just expect peaks over 100 amps? and set the current
limiting to insensitive? Or is there something else I need to
look for? Also, although PWM is set to 8 KHz, I also tried
OUTRUNNER and got pretty much the same result, a little less
hitting the cutoff.<br>
<br>
thanks,<br>
