Status: offline 		I’m installing a AR6210 receiver in my new plane with the DX6i transmitter. I have the EMS Heavy Duty Y-Harness. After I bind the receiver the ailerons both move the same way. How can I reverse the other aleron?

Status: offline 		If the aileron servos are on their sides in the wing then if you mount the servos output bushing on each side either both pointing toward their respective wingtip or both pointing toward the fuselage then both will be operating in the correct orientation for ailerons. When using a simple Y harness then this servo orientation is what you must use.

Status: offline 		well you may have a problem...using a Y harness you can not reverse one servo with your radio....the servos need to opposite of each other or the servo arms opposite of each other...in other words both servos facing each other or away from each other if mounted on their sides or the servo arms either point toward or away from each other if the servos are mounted flat.
Now this is not the end of the world... hook up the second aileron servo to another channel in your radio which is best or get a reversing Y...In a Futaba set up I think its channel 2 and 6 I'm not sure on JR/Spektrum

Status: offline 		At least with the Dx8, if you select the wing type showing two aileron channels, it will assign a channel for each aileron. Aile and Aux1 I think.

Status: offline 		JeffInTD.... Yes... the DX6i also ....but he's using a Y-harness... one channel (ail port) splitting the one signal.

Status: offline 		Yeah. I'm saying I would change that to two channel ailerons with no Y. You can then reverse one servo via the transmitter. To me that would be simpler than using a reversing Y.

Status: offline 		Thanks to all that replied. The problem was the servo was backwards on on side. Once i reverse them all was good. For the life of me I don't know how he flew this plane. Now I'm thinking he never flew this plane. Again thanks fo the help.

Status: offline 		When you say "the wrong side", what do you mean? Take a look at the quick sketch. The one on the right is not the correct method. This will have both going the same way. The setups on the left are the right way to do aileron servos. I just want to make sure the OP knows what the proper setup is. Both servo arms on the inside or the outside, but not one on the inside and one on the outside. This will work just fine with a Y cable to one receiver channel (aileron channel).

Status: offline 		CGR's excellent drawing illustrates what we have been trying to describe verbally when one chooses to use a Y cord on two airlron servos Also there is nothing wrong with useing that method.

I realize mrcoolpop that you have fixed your problem by orienting your backward servo that the CGR drawing shows but in case there others out there with the same problem but their Servos are a surface mount This is how the orentation is done. Surface mount are real common with small foamys.

In this case the servo arms must point on both sides either both toward there respective wing tips or both toward the fuselage and this will also give you the proper goemetry to properly operate your servos with a Y cord.

Both of these methods either the servo flat on a mounting plate or the surface mount is a good habit to get into even when you are not using a Y cord but two channels instead.

In these pictures the Red airplanes have the servo arms arraigned to point to the wing tips on both wings but they could also both point toward the fuselage just as well such as the yellow wing:

Status: offline 		One thing to remember about the Y-harness is there are two types - standard and reversing, and each has different applications. Regardless of which one use, you do have to pay attention to your servo setup - they both need to face the same orientation to the center line of the aircraft: output shaft facing down, up, outboard or inboard as shown by CGR's diagram.

The standard Y-harness will allow both servos to turn in the same direction. Use this for ailerons when you need to move control surfaces in opposite directions.

The reversing Y-harness will allow the servos to turn in opposite directions: one servo to turn clockwise, the other to turn counter clockwise. Use this for flaps, dual elevators, spoilers etc where you need to control surfaces to move in the same direction but the servos are on opposite sides of the fuselage center line.

Status: offline 		I'm wondering why would anyone with a radio that has a dual aileron setup opt for a Y connector? Using the dual aileron mix on your TX will lead to a better flying airplane.

Status: offline 		Another advantage of using two separate channels on your receiver is that you will be able to adjust each one from you transmitter and it doesn't affect the other one. On Futaba radios, channel one is for the right aileron, channel 6 for the left. Adjusting either one from your transmitter doesn't affect the other side.

???????????? Question of the ages but I know people with 9 channel radios that use the Ys. As my basic instructor told me, it was my plane, I could do what I want with it. I haven't used a Y sense I quit using the 4 channel radio but others may find the Y just easier? I'm a big fan of easy.

Status: offline 		OK here goes and I can offer one little tidbit and its certainly not binding to everyones senario but since I too am a a fan of Easy consider this:

Maybe its early am at the crack of dawn at some event hundreds of miles away and ya got a million things on your mind its cold and windy. But you are determined to get a trim/needle flight in before the event and competitors or heck just like this morning at my home field: Colder than snot but determined to at least to get in one flight with my trusty little china arf Ultimate and OS AX before I had to beat a retreat to the burn barrel. All the while listening to the good natured ribbin by the buds for even trying to put an airplane together.

Not the most pleasent situation to be attempting to put an airplane together. Conditions the mear act of assembling an airplane with the wing balanced on my head and plugging in a bunch of plugs (from one to a bucnh?) with the wing ballanced on my head as well as my wheechair berings screaming "Oil Me" in the cold.

Now consider these conditions and not having to identify which of those two wires hanging out has to go to which plug Marked or not is a big, big functional help to some of us. Instead I can simply plug any plug to any lead and not worry.

I will confess not sure if any one else will but I will, confess to having assembled many an airplane to fly only to discover its miss plugged. Back to square one balancing the wing on my head.

Now I have plenty of airplanes and while I do actually on most use a separate channel for each aileron but indeed do have some with two aileron servos Y corded and that was on purpose for the the small tid bit above. You can call that one of my keep it simple stupid (kiss airplanes)

I also must agree to disagree on the point about not being able to properly adjust the ailerons unless the are on two channels. This because I have never run across any airplane that was not easy to adjust mechanically. The point of me decribing how to orient the servos properly for this was for the OP's information so he will know how its done. I make it a practice of mentoring all the fellow I teach in these simple methods to everyone as useful and simple practices.

John

Status: online 		Just a note to all those recommending using a reversing Y for the ailerons on a Spektrum/JR system. DONT

http://www.spektrumrc.com/Experience/InstallationBestPractices.aspx

Don't use electronic reversing Y's

They can cause issues. Run the servo directly to the receiver, or use a reversed servo as a last resort.
