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. <o:p></o:p></span></p>
