Hi guys, okay Im setting up my trex 700n with the new DFC head and beastx unit. I have set up multiple of these units with no problems.

Well, I put the balls on the inner holes in the servo horns (round horns) and I cant get the blue light until 7.5 degrees cyclic. There are no other holes on the bell cranks to put the balls, so I am stuck.
So should I just adjust it 7.5 degress and the blue light comes on and say its good (it says 6 degrees in manual), or should I put it at 6 degrees, and leave it with the purple/ red light on?

AND, another question. When I first started out setting my max pitch range, it had 22 degrees. When I lower the pitch to 14 degrees max, I only get a red light. 18 degrees I get the blue light. Negative pitch I only get a purple light at 14. I dont want to continue and fly it until I hear some answers first. So should I say forget what light is on and fly or ?

Thanks for the help in advance!

6 degrees is what the BeastX requires to function properly.

The light is an indicator of how efficient your setup is in regards to servor resolution and head geometry. I have flown with helis that get 6 on blue and others that don't. I haven't ever been able to tell any difference. I no longer pay any attention to the light.

Set the 6 and go with it.

You can use the 700 e bell ranks and that will get you closer to the blue light at 6 degrees

Ah, you stole my thunder . But yes this is the way to optimize the geometry. You'll need the two bellcranks as well as the 700E elevator lever. The nitro elevator A arm fits right on it, secure the screws in the inner holes on the arm. Same with the bellcranks, put the balls in the inner holes.

I did this on my 700N and I get the blue light exactly at 6 degrees (it also becomes nearly perfect geometry for the Vbar and 750 setup that way).

But believe it or not, the Beast will still fly just fine even with the older nitro bellcranks and ele lever with too much throw, but it won't be quite as solid.

So you can get by with it the way it is...

if you use shortest possible ball on swash, you should be able to get blue just shy of 7 degrees.

Oh good idea! I never even checked to see if there was short and long balls on the swash

Okay another question which I have never ran into this issue. I have all of the servos perfectly centered at midstick. And when I go negative, the swash tilts slightly to the right. Then when I go positive, the swash tilts slightly to the left.

What's going on here?

All ATV's are at 100 percent. I looked at and tried parameter menu A, but that seems only for midstick.

the simple answer is "do not worry about it".
With swash level at center, the BeastX will take care of adjusting for any flight deviation from what the aileron and elevator signals are commanding.

If you get actual odd behavior in hard positive or negative collective, see Parameter A description in the guide.

Okay sweet!

So what exactly does parameter menu A do? I have tried it and read the manual and seems its only for midstick and not full pos and neg. But the manual says its exactly for what my issue is. I don't understand it one bit

Setting up my synergy n5c again and noticed my swash tilts the same way. Left full pos. Right full neg. But level at mid.

Did you ever figure out how to fix this?

Thx
