Why WOULD you want to set it up?

Is the plane doing something that you need to correct?

Your RV-9 shouldn't need it, as it is not a 3D plane nor prone to adverse yaw.

The best idea I've seen so far is to simply keep it simple. Using a Y connector into the aileron channel is the easiest and probably the safest way to get started with this. Safest because it's pretty hard to mess it up. No mixing, no alternate channels needed, nothing like that. All that needs to be done is to make sure the servo linkage is set up right, connect the ailerons to a Y connnector, plug that into the aileron channel, make sure that the channel is not reversed, then fly the plane.

And, as already said, for the RV9, not much more is needed.

Eventually, if you really want to use mixing and two separate channels, at least you will know that the plane flys just fine with it the most simple setup. Then you can go as advanced as you wish.

But, as also stated, this IS a beginners forum and we realy try to keep things as basic as possible, which is what will get everyone up and flying. More advanced setups are for more advanced pilots that are familiar with both their planes and their radio.

Well OPJOSE, Inever said I wanted to put aileron mix in, Iwas just simply inquiring about it.

I have flown the plane with the y connector hooked up, and it flew great. I changed to the separate channel separate servo setup and it flew exactly the same, as I figured it would, but I am keeping this setup, a because there is one less connection to potentially fail, a marginally small amount of weight savings, and just because I like the fact that I can adjust each servo separately. I was also talking with a local pilot and he said, while it is extremely rare,if one of the receivers aileron channels died mid flight, at least i'd still have the other one to land the plane with, not the case if using a y-conn.I'm not sure why people are making this sound like its such an advanced setup. The only real reason that I can see to only use 1 channel and a y-conn for ailerons is if you don't have the extra channel in your receiver.

Anyway, thanks again to eveyone for their help with this matter, and I do appreciate it. My plane will be staying right where it is with separate channels for ailerons.

P.S. If anyone is looking for a 3 inch y-connector, I might know where you can get one real cheap.

Not to knock dual aileron channels, actually it's the other way around.

Having a "Y" connector installed reduces complexity and a potential failure point.

It is far more common to accidentally change a setting on the TX that will completely throw off the plane's handling in a dual channel setup.
Also if one channel goes on the RX, they all go.

As you'll see advised time and again here, it is important to NOT rely upon the radio to get your linkages set up correctly.
Better to set things up with your "Y" adapter if possible.

On most TX's the signals for each of the channels is sent out in a serial manner.

So your right aileron will get it's position signal first, then, the elevator, throttle, rudder and left aileron.
That causes a noticible delay in surface movement, particularly on larger surface, as you bounce from one extreme to another.

Some TX's try to work around this by resequencing linked channels (e.g. what Spektrum calls "Servo Sync" ), but that underscores yet another small problem that comes into play.

As I said I'm not knocking dual or multichannel use for various surfaces or channels, but to call a "Y" adapter "more complicated" or introducing more failure points is a bit disingenuous.

Just a little known fact but JR/Spektrum advises against using amplified and reversing Y harenesses with their 2.4 systems. (not that its what we're talking about here, but another reason I recommend using the features in a transmitter if they and the receiver support it)

Yeah I also find that reversing harnesses only recondition one channel, introducing delays to the reconditioned ( reversed ) channels.

These units often feature "pots" to make the adjustments, and these pots wear out easily with use. Also the crystals used drift with temperature changes, forcing frequent tweaks to the fragile pots.

Better to use a "reconditioning" device such as a JR Matchbox if you want to do this outside of the TX.

The Matchbox takes the incoming signal and sends it through it's own dual ( or quad in this case ) circuitry so that everything is in sync.
It can also be separately powered lowering the demand upon existing electronics. That's why we often see Matchboxes and the like on larger more expensive planes.

For smaller planes I prefer mechanical solutions as much as possible, then dual channels.

On Soap Box:

Not just smaller planes, but for those that really don't need all the advanced capabilities.

Consider a Tiger 60. Does that need all of the crap that an advanced transmitter offers or does it really care? It can be flown with the barest minimum of direct setup and mechanical linkage and without all the fancy mixing, and flown very well.

This is the idea behind a Beginners Forum. "Beginners" being the key word. There are occasions when we can mention or even offer suggestions advanced settings, but not in a way that it is the only way they can fly an RV9 or a Tiger 60.

Given a Vivat or Focus 2 meter pattern plane.. well, all bets are off, but as I said, those are NOT beginner type aircraft and the settings are definitely NOT at the beginners leve.

Off Soap Box.
