Thank you Peter.  Very detailed.  Are you an Engineer?    :)

No, I am not, Crist. I did however have the privilege to head R&D staff for many years. This then brought with it a certain understanding for the need of accuracy...

Completeness, too.

So, did it work?  How well?

Approx. 200 flights on two airplanes. All components work flawless, regardless of outside temp. No maintenance done. Motor bearings feel like being perfectly ok.

All ESC parameters seem to be correct, no problems whatsoever. Repeatability is close to be perfect, all temperatures remain well below limits.

Earlier used low cost 25C batteries did not reach more than 30 cycles and I have just recently switched to four well kown brand 65C types. So far approx. 20 cycles on ea. with voltage logs showing no indication of unusal drop and batteries remaining cool at approx. 35°C
