I dont know what a phase ring is.

Id recheck the paddles and see how that helps, thats what I was thinking.

The phase ring is the ring just below the head block with the two guide pins for the washout block. If it's not lined up right it'll cause the head timing to be off which would result in some left-right cyclic with fore-aft cyclic being applied and left-right input would result in some fore-aft.

...yep...

so I put in black like Ace's pic, but it wont go to the top of the tank either,

Some hobby shops have it or automotive stores. It is thin and very flexable. If you are going through the side of the tank maybe the tube can't be long enough.

Ohhh, hmm, I put that phase ring thing in what looked like the right position according the manual.. Im new to this ccpm setup stuff, so thanks for bearing with me. Maybe someone can shoot me a pic of theirs from the side so I can view one setup?

Actually my Rator's that have metal heads have a phasing ring also. It's a good thing since you can adjust the head timing if needed but you need to make sure it starts off at 0 and only adjust if you know everything else is right.

I'll post a closeup pix tonight of what mine looks like. You can kind of see it here, basically it needs to line up right with the slots in the main hub.

...yep...

Ok, well, I played with the paddles, they are very close if not on the money, still does the pitch up.... do you have to adjust the servo's in CCPM settings in the radio? Frustrating having a bird that hovers good, but nothing else yet, haha. Thanks.

You can have them what you think is good, but are they even with the swashplate?

I make sure that the paddles are even with the SP, and make sure the swash is level, then bring it to a hover, and add weigh to the nose, till it stays in a hover without trim...

The Predator should track fine without nose up BS....

Thanks Bill, Ill double check that, and the paddles screw on hard, so I dont think they are stripped..

Do you think the MAH blades could be part to blame?

Its possible when running very light blades..3Ders love light blades for flipping as such, but if your into FFF , you need to get a more FAI type weight..
Paddles have a define effect on all this too...The grey paddles do fine for 3D, but the black is for more fff...
If you like to do both, then use the grey paddles, and use weights to position till you like best of both worlds..

Your into gassers now, so things count, its not like a light glow powering thru each maneuver with any combination...

RotorTech has this down to a art form...The 710 is very good at both ends with their 3D blade, because it has good fff characteristics also.
But if you want more, the Scot Grey versions are made for the job if you like fff and FAI type manuvers ....

Are you running Stock paddles?

Yes, stock paddles, and I have not gotten the thing into FFF yet, maybe 15mph from one end of the field to another, its most annoying when coming back into a hover, thing wants to keep rolling back to the right a little too.

I noticed, that when I move the collective from low to high, about mid point the paddles move a little, Ill try to get a little vid of it and post it if I can.. Nothing is obviously making them move though..

Noticed something in your pics...the spacers on the main blades...shouldn't the blades have equal spacing on top and bottom ?? Seems only spacing blade up or down from centerline of holder could have some weird effects... Food for thought.

It's OK....It's not your fault !!!

Got me on that one, I can probably seperate the washers, when I got them they had rubber spacers on it..

This bird has me baffled.

The one item that stuck out for me on the pictures is the last photo. Might be the angle of the picture but it look like the swash is level but the controls are not lined up. In other words if the swash is level the left and right side control cranks should line up with each other. Also when the blades are at 0 deg and the washout arms are flat then the servo links should be 90 deg. to the center of the servo horn. I would take a good look at the linkage setups. Look at pg. 23 in the manual for a reference to what I'm writing about.

Good call! always have blades centralized.

looks to me like the elevator link is not long enough. The right angle links are from center to center of pivots. Don't get fooled by the angle of the control arms.

Odd, elevator arm does look short at that angle, when I set it up though, everything was square..

Call Century
ask them if Cn2220A main shaft thrust bearing kit will
work on your heli.




Enjoy the hobby.
