motor to
ensure that the screech does not happen. If you are very close to full
throttle on the ground before surging happens (and light comes on and
off), I
seriously doubt the surging will happen in the air, as the amps will
drop
considerably in the air as the prop unloads.<o:p></o:p></span></font></p>

<p class="MsoNormal"><font size="3" color="black"
face="Times New Roman"><span style="font-size: 12pt;">I checked with
Dave on my settings and there was
nothing unusual. I was on a much older firmware 2.16 I think and
updated
it to 3.2 I am more interested in having trouble free flying this
weekend
rather than knowing for sure if it is the ESC/connectors or what.
(I'll
work on that later) There was some pitting on the tips of the dean
connector,
but I doubt that it was the issue. So I updated the programming on my
back up ESC and installed that one instead. <br>
When testing it I noticed something else that I do not know if it is
normal or
not. I use fixed endpoints on the throttle. With the prop off, at
full throttle the red light comes on steady at around 66% ATV (Futaba)
indicating full throttle on the ESC. I put the prop back on and
watched
the ESC (never did that before so I do not know if the behavior is the
same or
different.) The red light comes on for a second as the throttle nears
full and then goes out. It seems to want to get to full but can't due
to
the prop load. I can hear a slight bit of surging as the light comes
on
and off at times at full throttle. Varying the ATV doesn't help.
Prop is PT models 21 x 14. Is this normal? Should I just leave the
setting as it was with the prop off? Should I put back the other ESC :)<br>

really think you may have a simple setup timing
issue. I’m curious as Dave L suggested if you had some different
throttle “habits” that changed when you were recently flying (such
as a new pattern as Dave suggested). It sounds like the sound that
happens when a rapid increase in throttle gets the controller ahead of
the
motor and you get that electronic backfire squeal. And again,
this may only happen with your best battery packs. <u5:p></u5:p></span></font><o:p></o:p></p>
