Tail setup

[smartthumbs]

I’m finishing up a flybarless X50 nitro & have a question about the tail setup. Should the tail pitch control lever be 90 degrees to the tail boom at neutral? If so, then I’m getting more travel one way than the other when setting the max limits with my controller (ikon, if that matters). 6mm one way & 9mm the other. I figure I have 3 choices. Please let me know which, if any, of these I should go with. Also, the servo horn IS at 90 degrees at neutral.

1. Set the tail pitch control lever at 90 degrees, set the travel limits to the max each way even though they are different & let the controller sort it out.
2. Set the tail pitch control lever at 90 degrees, set the travel limits to 6mm each way. One way won’t be maximized but at least they will be equal.
3. Set the tail pitch control lever to a position that will put the tail pitch control slider in the middle of it’s travel, ensuring equal travel to the max limit each way.

Thanks in advance for any help.

Thats about what I ended up with to. I have a AR7200BX and I 90'ed the arm. I got a lot more push than pull. Flies great so far..

I would stick to setting 90 to the boom. That's common practice.
Also one way having bigger distance than the other might not be problem. Consider that heli naturally has spin (physics) and tail rotor is there to compensate the rotation. Now logically to achieve same rotation speed in direction opposite to the natural spin you have to add more on pitch on the tail so i wouldn't think it's abnormal to have one side with more pitch than the other.
I can check how mine behaves but i am currently servicing engine so heli is all disassembled for at least a week or two.

Okay guys, thanks so much for the help. Option 1 it is.

I was thinking of this when I looked at mine this morning. With the lever at 90, my concern is the neutral position pitch of the tail blades is wrong. I would suspect the tail would be steady if in rate. I was thinking I'd set mine so that there is about 3 degrees of "bite" into the boom for a proper neutral. No doubt will fly fine either way the modeler chooses to set it, but I think that it may lead to the tail servo over working if not made to have a steady tail in rate. Not an expert opinion, but it seems to help tail performance when set correctly.
