That Elusive Reverse y?
 

I have a U-CAN-Do 3D.46 and as u all know it has split elevator halves with 2 servo's... I don't plan to do any mixing with the elevators so I'm told that I need a reverse "y" connector. Does any one have a link to one of these? I looked at tower but I didn't see one... Please help!

Id have to plead ignorant on the reverse y.... You could probably make you own reverse y by just soldering the red and white on the pigtail to the opposite colored wire on a servo extension...


You can probably achieve the same thing pretty much by just putting the servo arms 180degrees opposite of each other as long as the servos are centered.

I know you said you dont want to use mix but if you have a computer radio it would be so much easier to just activate the mix though. What kind of transmitter are you using?

Don't reverse the red and white wires on the servo extension.
Assuming standard (non-digital servos), the black is ground, the red is +5V, and the white is the servo position.
Connecting the red wire to the white wire will either fry your servo, or make the servo move to one end of it's travel and stay there. (I haven't experimented to find out which one of these two options actually happen ;) )

To have a harness reverse the servo direction, I think it might have to have some sort of electronics built into the harness. I think your best option here (since you don't want to do mixing) is to reverse the mounting direction of the servo, or reverse the servo head. You should be able to set it up so that both servos work together to move the elevators without mixing.

I have a Futaba 6EXA radio...Well you guys have persuaded me... I will just reverse 1 of the horns.. But I still need a "y" connector<only a reg. one right?

I would recomend against a servo reverser, all the ones I have seen at the field seem to delay the motion of the reversed servo or do not center well. Your best bet would be to try to turn your servo 180 and try to keep the proper geometry or if that is not possible most digital servos can be reversed. I had servocity reverse a Hi-Tec servo for me on my last order.

Thanks for the education Tommy. I wasnt sure and I figured someone would make it right...;)

I have a couple of reverse Y's and they work fine. I have no problems from them at all, and it sure makes setup easy if your transmitter doesnt have the the mixing for it. I am sure you can find one if you decide to go that route. If you can't post back here and I will find you one. Good luck.

here you go, and I've used a few of them, they work nicely

You can open up the servo and reverse the leads to the motor and the potentiometer in the servo. This will make a standard analog servo work in reverse direction. I did this once before I got my 9C and it worked great. Oh, the potentiometer has three leads on it. One on each side and one in the middle. The two on the outside are the ones you want to swap.
