????????????????????

If you are refering to my post, I said using the same profile for two differnt plane, not fly two at the same time. That means that both planes have the same servo reverse settings, same trims, same dual rates, same exponential, etc. This way you can take your 4 model memories and make them applicable for more than 4 planes.

Going back to my example, the Spirit and the Sagitta were both 2M RES sailplanes ( 3 channels ). I redid the servo linkage on the Sagitta for the rudder so that it matched the direction on the Spirit. Then I worked the mechanical adjustments so that both used the same end point adjustments, same dual rates and same exponential. If there were any unique changes I wanted to make to one plane or the other I had to do it via the linkages on the plane, not from the radio.

Making adjustments from the radio is super quick and easy compared to doing it on the plane. But that is how you stretch your model memory count to handle more than that many planes.

Hope that clarifies it.

( flying two at once? Had not thought of that.)

(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)!

The JR S600 is a good choice because it has 10 model memory, dual rates, expo, and the price is right. Only $159.99. This radio is part of JR's new Sport line. Great choice.

Odd, but the S600 is not listed on the JR web site.

This is a very basic computer radio. Not a lot of mixing offered. I would really like to see a flap/elevator mix for landing and an elevator/flap mix for aerobatics. Note that this price package $159, has standard size servos. Good for 40 glow planes and some 2M sailplanes, but typically too big and heavy for small electrics/parkflyers. Receiver is not too big,however.

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.

Piper, a simple and almost fool proof way of handling this potential problem! I like it and am going to make use of it!
