Phasing ring?

[OzarkCopterBum]

After my crash last week I did notice a new vibe so I replaced the mainshaft last night. Easy enough till I got it all back together and noticed that my pitch had changed and is "off center" meaning I can only get -2 to +15. I had also replaced the link for the collective so I went back and tried to setup from square one. Anyway got pretty much the same and was scratching my head for awhile till I noticed the upper links touching the phasing ring so I loosened that and spun it to around till it stopped. The links werent touching and it helped the pitch but I still only get -5 to + 10 which is fine but not what it was.
What am I missing?

Wow Thats a tough one.
Did you by chance put the mainshaft in upside down. Lokk at the bottom of the shaft. If the shaft is sticking out the bottom it is upside down.
check to be sure that you did not put the mixing base on upside down.
Make sure that all of the links are going to the correct placees.

It sounds like it is a reassembly issue if the pitch was good before and now is different.
Make sure the the Phasing Ring is set per the instructions or you will have big problems.

Fourtunatly all of these things can be checked by just looking and comparing to the pics in the manual.

If this does not help, we will have to dig deeper.

Yes I did put the mainshaft in upside down but figured that out pretty quick when I put the pitch gauge on and had like -18 to +3 hehe. :roll:
I'll go over it again tonight when I get home and dbl check everything. I think the part I was referring to is the #455131 washout guide. I dunno where I got phasing ring from. I guess it sounded more important.

It has to be either that or the actual link as they are the only things I messed with. I made sure the shaft was the same length, that the jesus bolt was installed and the mainshaft lock ring was seated correctly.

Hey Ozark,

There has to be something reinstalled backwards or upside down..... 'er I think. I am like Jeff, this is a tough one. I will be glad to take a photo of my setup and put it on here for you to look at, in comparison. Just let me know.

[OzarkCopterBum]

I have one sitting right next to it and they are identical.

Anyway, fiddled around last night and was able to get +11 to -9. The low end is with the pitch control arm all the way down to the frame. All I can think is that the shaft is slightly longer or shorter of the holes for the jesus bolts are different. I'm flying it like it is.

Also, after all that its still got the same vibe, hehe. Still need to go through the tracking and tighten that up some. I have a VERY hard time seeing which ones off. I can hear it better than I can see it.

[flyinfool]

There are two ways to attack the tracking.
One is to color one of the blade tips so that you can see which is higher.
The other is to mark one blade and grip as the "master" and make a small adjustment to it.
Then hover again to see if it got better or worse.
If it got better then you are going in the right direction.

[Hotshot Charlie]

The way I do the Master/Slave blade is, during setup, I set one blade as the Master, I then make all my pitch settings with the pitch gauge on the Master blade. When I get to the field, I make tracking adjustments only to the slave blade, since I have the Master set where I want it. I may be doing something wrong, but it works for me.

[flyinfool]

Your right Rob.
I ment to say to make one master and adjust the other one. :oops:

[Bklyn]

I do the almost the same as Rob, but after the Master is adjusted, I also do the Slave. Sometimes, at the field, I don't have to touch anything after checking the tracking. At least I know that it should be close.

[Hotshot Charlie]

Your right Rob.
I ment to say to make one master and adjust the other one.

I was sort of "fishing" because I wanted to make sure I wasn't doing something backwards. heheheee :shock: Now that wouldn't be the first time I did ! :arggg:

Hey John,
I also will work on the slave blade like you do, it makes tracking easier, like you said. Thanks for your input. I am like Jeff, :oops: , I should have stated that also.

[OzarkCopterBum]

On a Stinger are you adjusting the short links?

[Hotshot Charlie]

"On a Stinger are you adjusting the short links?"

Yes, unless there isn't any more turns one way or the other, then you move down to the next link/rod.

[VTHELINUT]

HI
I'm no expert but !
I adjust the long links that go's to the swash only. I never touch the small links, I set the small links the same on my link sizer and never touch them. The small links are touchy. you can fine tune it better with the long links.

[Hotshot Charlie]

I'm no expert but !

Me either, Mike.... but I did learn from a guy that's been flying heli's for over 20 years, and that is the way he showed me to adjust the tracking. I have been doing it for 2+ years and it works for me. :mrgreen:

I don't think it really makes much difference, your adjusting the same thing at different places, albeit, one might be a little more "sensitive" than the other. :wink:

Ya'll have a great week !

[ChrisLaFollette]

I adjust my tracking the same way as Rob. I set it up on the bench with one blade and mark an X on the Grip and Blade then I adjust the tracking with the other blade. Works Perfect. Woodies to make a little bit of a chirping/whooshing sound so if your flying woodies you may think there out of track when they really arent. I hover my heli eye level and kinda tip the disk around so you can see the blades perfectly level. Kinda hard to explain but you can tell if there out or not. It sure does feel good once you have them tracked and it floats in a hover like a feather. :mrgreen:

[OzarkCopterBum]

I got em tracking pretty true. I did adjust the shorts, all it needed was 1/2 turn. Also I think I was hearing the paddles that were slightly off.

Anyone here use paddle gauges or just eyeball em?


Chris:
9C is MIA? That has to suck.... Somebody walk off with it at the field?

[ChrisLaFollette]

No I lost the WHOLE HELI while flying it at my house. Had a Mechanical failure, something to do with the tail and I lost it in the Pine Trees next to my house and never found it. Pretty sure the Neighbor stole it as he steals crap all the time but I can do anything about it. Read again it says "All but the 9C MIA. Out of the hobby as of right now." I am kinda browsing for a cheap R30 to fly. Something for 3-400 bucks.

[Hotshot Charlie]

I just put the ole' "evil" eye on them. Probably not the best way, but so far has gottem them darn close.

[flyinfool]

Chris
Hate to hear of that kind of garbage.
Sounds like your neighbor needs knuckle bumps.
I would report it to the police as stolen, post on the various heli forums about it being stolen, and watch for it at local swap meets, hobby shops, for sale adds in paper, eBay etc. Then sick the cops on him.

Eyeballing can be close depending on how well calibrated your eyeball is.
I have seen eyeball jobs that were out by more than 5° that the owner swore were perfect. Others can eyeball so close that even with gages you will not detect a misalignment.
Eyeball it as close as you can and then borrow a set of gages to check the accuracy of your eyeball, if your eyeball is off a little, gages are cheap and easy to use.
Another check is to look at the tracking of the paddles.
There should be just one edge visible and it should be parallel to the main rotor while hovering on a calm day. If the path of the flybar is not parallel to the main rotor on a calm day, something is not adjusted quite right. It could be any one link that’s off.

[OzarkCopterBum]

That IS a bummer Chris. Keep watching the FS ads, You'll get another.

Ya know, learning to fly a heli isnt nearly as difficult as learning how to tune a heli. If I had a mechanic I'd be doing inverted auto's by now.... hehe

I was watching the tracking/flybar sunday and noticed they were not parallel, I couldnt remember if that was correct or not. There was a bit of a breeze so I'll be sure and check again when I get out today.

[Hotshot Charlie]

The flybar will move/angle with the wind. Yes, it's normal.

[OzarkCopterBum]

I did have the phasing/washout guide slightly off. I made that adjustment and got a little wobble squared away but even with the wind pretty still the flybar was not parallel with the blades. I looked it over and couldnt even begin to fathom where to start trying to adjust it.

Even so, its flying really good.
