Hi, can anyone help me, I've been reading the eBook and searching the web for a solution but just can't seem to find what I'm looking for. I'm rebuilding the tail elevator section of my F-18 V4 and I'm forced to (as has been since the first build) to place my two servos in 'parallel'. That would mean placing one in the past f the prop and I want to avoid this. I want to place both servos on the outside so that the servo arms are facing each other. My radio however, doesn't like this and moves the servos in opposite directions; that's my question. How do I set the servos up this way and have them running in the same direction when facing each other?
I'm using a Hobbyking HK6 radio with mixing. I was running a Y-lead to the two elevator servos from the RX elevator input. Would I need a separate mixer now? What's the secret if there is one?

I am not familiar with your radio, it mixes but you can't reverse the controls? If it is 1 servo going the wrong way put a servo reverser on it and then use your Y, if it is both going the wrong way, plug them into the Y and then the servo reverser.

What wildthing said. Alternatively, if u are comfortable with a soldering iron in tight places, hv a look at this.

I had a similar issue with a hobbyking Bixler where they had pre-cut servo holes for ailerons and flaps. While the aileron ones were ok, the flap ones needed, either a reverser or the mod shown above.
If at first you don't succeed, destroy all evidence that you tried.

I recently built a NAMC Mig 35B with a one piece elevator running from the 2 traditional servo positions into a Y-harness. I rewired the starboard servo to move in the opposite direction as blkbaron mentioned above, rather than using a servo reverser. My DX6i has mixing limitations as well and for the set up I wanted, reversing the servo wires seemed to be the easiest solution.

When you say the servos are running in opposite directions I believe you mean the arms are "opposite" in that one is pulling while the other is pushing.

The real question is are the servo shafts both turning CW or CCW when viewed looking at the screw?
If they are both CW or CCW then they are turning the same direction.
The issue is that they are mounted mirror to each other.

Many solutions:

1. Plug them into separate channels on your receiver and program the radio accordingly (assumeing your radio can do that).

2. Don't install them Mirrored.

3. Buy a servo reverser and install it on one of the servos (like Wildthing said).

4. Rewire one of them like said above already.

Good luck.

Oh, and some pics of your setup would help the discussion tremendously.

Thanks guys, before I came back to read the posts I tried an onboard mixer and that seemed to do the trick; one lead from the mixer into Elevator and the other into Channel 6 on my RX (extra weight that I don't need). I now wish I had waited a little to check the videos of servo reversing. That soldering option would have been a far better solution - but alas, you live and learn...

You will need a servo reverser on one of the servo leads after the vtail mixer. These can be bought cheaply from HobbyKing and saves all the hassel of rewiring one of the servos. Should be available from US and international warehouse.
