ORIGINAL: Mode One
(Sorry Ed)! I realize now, the website automatically put in (In reply to aeajr) However, what I was referring to had nothing to do with anything you or anyone else had said. The comment was a lame attempt at a joke. (Although a transmitter can control multiple airplanes, there shouldn't be an attempt to fly multiple planes at the same time). The comment about a guy toggling through airplanes in his transmitter while the one he was after, was running loose on the ground, actually happened. The throttle servo on the plane running was reversed from the last plane he was using. Needless to say, when he got to the plane he wanted, the loose plane hit high throttle, tore off in a hurry and smashed into the wind sock pole! (So, kids, do your programing before starting the engine)!
When I got my first computer radio I was very worried about doing this very thing. The simple solution I came up with is to attach something to the prop of each airplane. I use a piece of foam with a number, but something like a clothespin would also work. Before I can start the plane I have to remove the marker from the prop. Rather than just set it aside I immediately select the correct plane on the transmitter and then attach it to the antenna. When I switch planes, the marker goes back on the prop, I get the next one, change the tx, etc. By sticking to this system I've yet to begin starting a plane with the tx on the wrong setting.
