Default RE: In flight glitch - please help diagnose

I emailed Castle yesterday. Here is a response:

Hi Micah,

We talk with litterally thousands of hobbyists per week, and this is
something that looks like it may be starting to be a trend.

Apparently, when the electron 6 Rx voltage gets a bit low (strong current
going out to servos, and in your case, BEC power sagging a bit because of a
hot controller) it's reaction is to send all channels to 100% - as you've
observed. When it does so, in most applications, that travel is beyond the
"normal travel" you're using and the servo binds and stalls. A stalled servo
draws an excessive amount of current (more load on the BEC) and you can see
where this is headed - a downward spiral the Rx doesn't get out of, and any
ESC's BEC can't remedy the situation because it's maxxed out already.

A cooler running ESC would help keep the above loop from happening in the
first place (as would a different Rx) so having it in some cooling flow
would help yes.

I'd be happy to mail you a new peice of heat shrink if you'd like to send me
back your mailing address?

Thanks,
