Heh, good one. No, it's not that flaky.

It has a "set" button that you hold as you turn on the RX. When it does that, it comes up in a search mode. At that point, it does, in fact, find the most powerful transmitter and lock on that channel. From then on, it stays on that channel, until the set button is used again.

As for being the strongest transmitter, all you have to do it turn your TX on, and put it next to the airplane. Since TX power drops off as the cube of the distance, unless someone else has their TX right next to the plane as well, the RX will have no trouble figureing out which is the one you mean.

Now, if you wired up a device to turn off the RX then turn it back on in flight with the "set" button pushed.... Actually, it wouldn't work . When in "search mode" the RX slowly moves the aileron servo back and forth to tell you it's searching, and it does take a couple of seconds, so you'd splatter the plane for sure. Still, it's a funny concept.

Oh, I forgot to mention, the RX comes with a set button on a lead. it uses a regular servo plug, and goes in a special port marked (get this) "set" on the RX. So you can set the RX to your channel, then unplug the button and stick it in your field box or whatever. Or, you can mount the switch anywhere on your plane. The switch just hooks the signal line to ground, so you can even make your own "set" switch with as long a lead as you want, and mount it anywhere you want. The the RX isn't very expensive either. IMHO, it's one of the "great secret products" out there.
