It's hard to tell from the photo, but make sure that the servo rods have about equal lengths of thread showing at both ends. It seems like the link is almost all the way out of the servo rod at the servo end.

Also tilt back a little more your anti-rotation bracket. Make sure you're using the right holes for that.

Photocycler, It looks like you have the link balls wrong on the swash. The longer balls go on the outside where the links from the servos connect. The elevator link looks like it's at an excessive angle. What distance are the servo horn balls? They should be 16mm.

yea crappy picture, they are equal

I tilted the anti-rotation back, I am running it in the hold closet to the swash

sorry, can you explain how it is wrong, I used the stock savox servo horns which appear to be greater then 16mm, I may have to move in a hole

it looks to me like the long balls are on the upper swash, when the short balls should be there instead. The longer balls should be on the lower swash. Not sure if that will be enough to fix your linkage geometry, but it will get part of the way there.

the balls on the top and bottom are same length with the exception of the 2 longer balls that came with the FBL kit that I used on the top swash plate connecting to the mixer arms, is that incorrect?

I have since moved the balls in on my servo arms and got a much straighter path for the links

[wbefield]

with the long balls up top, I didn't feel like there was enough clearance and that they could make contact with the lower swash, so I changed them all the the short balls.

since there are only 2 longer balls, did you just swap them with the ailerons and keep the elevator the short?

[photocycler]

Ok switched servo arms ball links to 16mm (inner hole)

Swapped 2 cone ball links from upper swash mixer arms to lower swash ailerons

[d1esel]

You need three longer balls.

[d1esel]

If your head geometry is not set up correctly your BeastX won’t be happy. You need to be able to achieve the required collective and cyclic pitch with adequate resolution. Think of resolution as servo travel, more servo travel equals more resolution. FBL controllers typically require high resolution for best performance. Improper link ball location anywhere in the servo horns, swash, or grips will give you a compromised setup.

Ok cool, I got it, thx guys

[d1esel]

You need the ones in the FBL kit (MSH51120).

Wouldn't it be nice if Tammie's carried MSH.

[photocycler]

Ok wow..good to go, that shouldn't been as confusing for me as it was...all settled

Now Im on to adjusting blade pitch and with equal links, one side is a few degrees off, this leads me to believe something else may not be right as I thought equal links should give equal pitch?

[photocycler]

Ok long balls on lower swash, short on upper, ball links on servo arms are at 16mm,

When adjusting cyclic on my beastX the servo arms are hitting the frame when I get the blue light. Any recommendations how to fix this?

Double check the ball distance on your servo horns. I have some four sided Savox horns, and the outside hole is 16.5mm next hole in is 13.25mm. If their hitting the frame, you will have to move the balls back out. I had a similar issue setting up my vbar. Seems to be a bit of a design limitation with the Protos.

[photocycler]

I am using the savox single arm horns and am at around 16mm.

Hard to tell by this picture but , it looks as if ele servo has a lot of angle on it. You may be to far out on your servo arms , thus not getting blue light. If the swash arms are not totally level, as long as you are not binding, and have full pitch range = + -. not a problem.
I also left some info on your other thread regarding "savoxx servos"

[photocycler]

Ok confirmed, definetly at 16mm c-c on the servo arms. Some people say they are getting blue light others says I am fine with red light

[crickr1]

Almost finished with my re-build. Should be setting up bx tomorrow.
Sounds like your almost there, I'll double chk my ball links, size/location and get back to you tomorrow.The blue light is optimum, if you just can't get it , you should be alright as long as you lock in your 6deg. and have no binding.(if I remember reading a fe posts about that correctly)
Not sure if it was on bx forum or gaui??

[photocycler]

Ok I am sticking with the Red light for MAX Cyclic Limit on the beast and moving on

finally onto the last piece, ESC setup...Are there any stock settings I should change? I dont have a program card but would like to run the governor at 70% throttle with the stock 15t pinion
