Final setup on my new 600e pro dfc with stock servos vbar full size 5.3 pro.I am having geometry problem ,reduce the cyclic ring < 65 to keep the collective in the recommended 80-110 range but the cyclic is below the range.
I have the ball on inner servo horn hole.
Is this a inherent problem or there is a fix .

You might need to use shorter servo arms.. I am going to setup a 600E pro Dfc this weekend.. I'll see if I need shorter arms.

shorter arm will cause interference with the servo body.Thanks please let me know how your workout .Are you using vbar

It is a known problem. I just bought the KDE arms for my 550DFC. I was able to barley get it in VBAR limits. I had a 600 pro non DFC and that would not be in vbar limits either. I flew both 13 collective and 8 cyclic and they fly fine. That would be ny recommendation based on flying both ways the difference is very small.

Well, I just wasted a lot of time trying to get that to setup properly. I don't see how you can make it work. Shorter arms will cause servo case interaction at extreme collective and cyclic travel. I was using the stock metal servo arms on the inner hole. At 12.5 collective and 8 cyclic it will bind all over the place..

You can lower the cyclic ring to stop binding by pressing the professor icon. On the cyclic setup in the set up menu.

I don't see a cyclic ring adjustment on that page, just the slider

Click set up and then swash. I think it will be around 85 just drop it down and see if there is binding. If still then continue to lower till the binding stops.

It will be well below the mini 80% and 8 degrees

I set it up so the VBAR knew 12 degrees and 8 for cyclic. Then reduced the number till there was no binding. I was flying the 600 at 2300-2500 HS and it was a great flying heli. I like every thing to be right on a set up but I compromised on the 600 due to the binding and geometry issues. It is not perfect but it will still fly well.

Ok I found the cyclic limit in the swash setup area.

Here is the current setup. No binding..

Inner ball on stock Align arms
Collective +- 12.7 at 85%
Cyclic 8 degrees at 86%
Cyclic Ring 75%

Wow those are great numbers NQNA ,You have the stock arms ,balls at inner holes, set collective and cyclic then at mid stick adjust the cyclic ring ?

Ya thats the sequence I used. You could have a bit more cyclic ring if you drop the collective down to around 12 degrees (or what ever you can get with collective set to 80%). I have the 750MX motor so I opted for the higher collective value.

I am checking the cyclic ring value at the positive and negative collective maximum values.. Then reducing the cyclic ring value to eliminate any servo case interaction with the servo arm/ball.

It sounds like you have it figured out have fun. I really like the 600 Pro. Having the 750 motor n it will make it unstoppable.
