Georges,

With my DX6, until the RX/TX establishes communications, (which takes approx 2 seconds), it doesn't matter what stick input I give it. For the first two seconds, the ESC is going to see whatever the "pre established" position in the receiver is prior to making the link. On top of that I have a gyro thats trying to power up as well.

I'm beginning to think I want to try the switch fix. That way I can power up the TX/RX and let it get "linked", let the gyro get stable, and then put power to the ESC with Full left rudder.....therefore setting the low point properly.

Wow....I had never imagined this would be so darn difficult ! I work in Mexico so I'm at work today.....but I'll be doing more investigation tonight. Time to go to the lab and see if the Tech's have a toggle switch !
