Tail control rod not straight?

[Clay333]

I received my (new to me) used Logo 600 3D today. I got it put together mostly, but I am waiting on the seller to ship the landing gear to me so I can't really finish right now anyway. I noticed that when I put my tail control rod on it is not straight with the boom. I know that it isn't always straight on all helis, but on this one it is the whole width of the boom difference. Is that normal? I will be honest, it really doesn't look right to me, but is don't see any way to change it. I can't just flip the tail or servo to the other side. If. This isn't normal and you would like to see pictures of what I'm talking about just let me know and I will snap a few.

Also I am new to Vbar. I have always ran Beastx. The Vbar on this heli is a black sensor with v5.1 installed. I plan on updating it. Do I need to redo the setup since I will be using a different transmitter? I know with Beastx it isn't necessarily, but it is advisable to redo the setup. Is the Vbar the same or should I just bind, check for reversed channels and things like that and fly? Or should I completely start from scratch? Since I am not familiar with Vbar I would prefer to leave it alone as much as popular. But if I must I will start from scratch.

Thanks in advance for your advice/opinions. If there is anything that I may need to known about this amazing heli please tell me, so I don't have to learn the hard way. Thanks

Start from scratch :-) Its not that hard to learn and you dont want to be clueless should you need to redo something or trouble shoot.

Yes you should check all the setups again with diffrent transmitter.It probably wont be anything wrong but better double check.

About control rod it should be straight with the boom. Chech if rod is still strong and that it isnt crackes somewhere. also check if the lenght is still good enough.

Probably is better to replace than have a tail problems in the air.

Pics please.

There is nothing at all wrong with the control rod. It has one tiny little dent in it, but other than that it is completely straight and definitely not splintering. I got a fee pictures that I will post. I had to put a piece of masking tape on the boom so that you could see the control rod in the pictures. As you can see, the rod is straight, but does not run with the boom. I am not noticeable anything put together wrong, but as I said I am new to logos so that's why I am here asking. This heli does have the QuickUK tail on it, but I don't see why that should make a difference.

This is guide for tail rod.

That's normal on the logo 600. Whether the rod lines up with the boom is dependent on optimal tail geometry which depends part on tail servo location and tail pitch slider control arm among other things. Now whether or not the Logo 600 has optimal tail geometry, I don't know. But this is normal on it.

On my Protos 500, the rod lines up because I can control tail servo placement and the control arm with ball reaches center of boom diameter.

I have that part, it just isn't installed right now. I also don't have the horizontal fin or tail boom braces installed. I have fitted that part on there, but it doesn't change the control rod being crooked though. I am not going to put pressure on the control rod with the guide so (correct me if I'm wrong) it will no make the rod run straight with the boom. Thanks for noticing though

Yes, i know exactly what you are talking about with the Protos, and I have to say that I am a fan of the boom mounted servo. I like the fact that you can get it straight, move the servo for adjustment, and you control rod doesn't need to be tweaked when you change belt tension.

Would it be possible to get some sort of a stand off ball link to make the ball further from the servo horn? I am pretty sure I have seen them before, but don't remember which heli they were on and if they were the same size as the logo's ball link.

[pustinek]

Well you wont get the control rod perfectly lined up with boom beacouse servo is on center of boom and control arm for the tail is kinda on one side. So its normal that is runs a bit diagonally. I think just install that tail rod guide and line it up that was that control rod runs straight and smooth

Never tweak your tail rod when you adjust tension!!!

On the logo the belt is more thermally stable than the boom, so when you adjust belt tension you are actually resetting the tail geo to the correct distance!!!!

[Clay333]

I am glad you told me that. I would have definitely thought that if you moved the boom in or out for any reason that you should adjustable the control rod to compensate.

On all the logos I've built, I've just butted the links right up against the carbon rid when I glued everything together. The length has always been perfect or close to it. I tried adjusting one once and cracked the carbon.

[Clay333]

Wow, that sucks. The guy I bought this one from had some space between the rod and ball link. I have read that they should be butted up, so I screwed them down until they did. I didn't crack the carbon... Luckily. I did notice that it seems to align better with it screwed all of the way in. Now both the servo arm and tail arms are both at 90degrees.

. Mikado knows what they are doing.

The belt sets the distance all the way from main shaft to tail shaft

If you want to fly without having to adjust your belt again, then try a carbon tail boom. I haven't touched the tension from 35F to 95F. Works great.

[Kalpazan]

Be careful with those carbon booms. Some are not pure carbon but more like aluminum body with carbon shell, so not good. Stock Mikado carbon boom however should be fine.

[OverTemp]

Yup... Stock mikado. Pure carbon, very light and rigid.

[Laughingstill]

Make sure you push the boom all the way in, tighten it, then pull the tail case out to adjust the belt tension. Then if you pin the boom at the front and rear, it will never move.
As long as the CF rod for the tail is not tweaked, it will work perfectly. Good luck!!!!
