[NSRCA-discussion] Pletty CC HV 85 issue

[Atwood, Mark]

I 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.

The Axi motors used to do this a lot.

Yeah, I was wondering if it might be a mechanical issue, too. I had a foamy once that had similar behaviour, (down on power, strange squeal) and it ended up the prop shaft was slipping. BUT, it did it every time, not just once-in-a-while.

Just one season flying mostly once a week , so under 100 or so.

How many flights on the motor?  I wonder if could be bearings?
