I can't understand this number
however it must be 90 with a margin of 4 numbers.


From what I see there are two possible causes.
1 and I'm sure that's the problem, your 0 as I thought is not configured well.
maintaining position try to hold that position that you configured and this configuration tends to move the model

2 the vibrations cause the problem

I have to ask you this question, in your radio trim and subtrim are at 0?

PS
it's not set up right , the servo horn are not straight.
I can tell you step by step how to do it, but I think these are things you already know.
Why elevator is it so inclined?
the other two servants are not at 90, but slightly down.
swashplate not is level.
and I believe that the tail it is not set well, you have too much subtrim (but that has nothing to do with your problem, it's another thing)
Geolink if you are almost 90 is ok, so the problem is NOT THE GEOLINK

before putting hands give me confirmation if you have 90° in geolink.
how many vibrations do you have?
and that you don't use trim and subtrim on your radio.

this is servo 90°

do these things:
servo-subtrim tuning
move slider ch 1 2 3 to have this

with the servant in this mode you must have this (follow the red lines)

this situation you must have it turning the rotor 360 degrees, always the same
and In the end you must have this situation

Obviously put the blade in one point and measure the degrees, after at the same point put the other blade and measure, you must have the same degrees, this is for tracking
PS
note on the tail not is perfect I have to fix it again

Thank you i will recheck my setup. I do find with the 450 pro getting the servo exactly 90° by eye difficult. Is there a trick or tool to get it 100% correct.

I have run calibration for the geolink compass but with my heli at north on the hand held compass the geolink is stating 84°

Is there a certain tolerance? I can manually adjust in settings but only by +-45°

Can the compass calibration be done wrong or is it pretty fool proof?

Thank you for your help by the way this is all new territory for me.

Hello,

84° is still acceptable, so it should be OK.
Calibration can't be done entirely wrong, but it could be done more precisely by moving to angles where LED light is flashing more frequently - with more gentle movement around to make sure GeoLink's LED will not flash anymore there.

If you will use 6° degrees correction then it will be perfect very likely. However it is easy to see with Position Hold. If model will be really steady then calibration is good.

when I calibrated the compass I had some doubts.
When I made a tight movement I noticed the light changing
and then after I widened the movement.
But then I arrived at a certain point where the calibration never ended.
And it took me a long time.
I believe that I didn't understand good 100% all circular movements to do.
How the black lines of the circle of this image (I only made one to get the idea)

I move making a small circle how la prima linea nera, after movement how the second black line ecc ecc.
But then never finished calibration.
Exactly to complete compass calibration all the movements to do Which ones are they?
i remember i was at least 20 minutes when instead it had to be completed in a few minutes
