Greg..

Thanks for the info, but you're thinking a bit "old school". If you're flying 72 mhz, it's important that your transmitter is always the 1st to be powered and the last to be shut off since any other transmitter on the same channel could start you prop spinning when at the wrong time.

Not so with 2.4 ghz. Even Spektrum says it doesn't matter in which order things are powered since, once the initial bind process is done, they share a unique code. In fact, after your flight, the easiest way to pervent a prop strike injury from accidentally bumping your throttle stick is to turn off your 2.4 ghz transmitter. That is, so long as your ESC failsafe throttle position set up correctly. Even if the ESC is in "failsafe" it will still be trying to connect to your transmitter, otherwise you'd never regain control after a "brownout".

Anyway, it's a well know problem that the DX6i and the AR6000 that have already been bound together are finicky in connecting to each other on subsequent flights. This is why we who are affected by this try powering and unpowering our equipment is various combinations to try to get things going and fly. So this is one of those "tricks" that seems to work for me a majority of the time. But once they are connected, they are rock solid and it's a great combination.. Although it's still just a bunch of black magic anyway...

P.S. The Spektrum DX6i has no lights that illuminate upon power up. You may be thinking of the DX6, which binds quickly and easily to my month old AR6000's. Most speculation on this issue has to do with the DX6i having to communicate with the AR6000 under the older DSM technology vs DSM2. The DX6i is backwards campatible, but it's not as seemless as with the newer DSM2 recievers it's designed for.
