Hi, i have the cc3d atom, when i plug in the battery, the escs make the arming sound in different times, but the quad flies just fine, is it ok?

Thanks!

That usually means that you have different (firmware, brand, date-of-manufacture) ESCs.

I would check the output page and make sure that they all are set to use the same protocol.  You can just set the bank protocols at the top of the page to the same type if you can't figure out which banks are important for the ESCs.  That assumes that the only outputs you have are ESC (no gimbal, no servo, etc.).

Hi, i have used this quad with the same hardware but with open pilot and it was just fine, so i guess theres no problem with the escs, you say i should make the banks the same?

If it flies fine, you can leave it as it is, but I like to have mine all set correctly.

To answer your original question, motors starting a little differently doesn't usually hurt.  Where it can is when doing stunts and one motor stops, sometimes it takes a little longer to start a stopped motor than to start a slowly turning motor.

Each bank can have one or more ESC output in it.  Look at the top of the output page and make sure that the banks for channels 1,2,3,4 are all set the same.

If they still don't start the same, use the ESC calibration and motor neutral procedure to make sure they do:

hi, thats what my banks look like:

i doesnt look right to me, how can i change them to be the same?

There are two things "wrong" (but not so bad...).

See how your first 3 motors use bank 1 and motor #4 uses bank 2?  That means bank #1 and #2 must be the same.  They already are the same, but 50Hz is very slow Update Rate.  Try PWMSync on banks 1 and 2.  It will make it respond with more "locked in" feel.  You should do ESC calibration and motor neutrals after changing ESC Update Rate.

Your motor neutrals (how fast the motors spin at very small amount of throttle) are somewhat different.  The last part of the "ESC calibration and motor neutral procedure" will correct the motor neutrals.

- i did what you said, niw some of of the motors had much lower neutral point than others. is it bad?
- i just raised the ones that had low point to match the ones that had high points. is it ok?

- if my most "extreme" flight mode isnt extreme enough for me, how can i make it more extreme?

- can you help me with video problems? or is it not the right forum?

thank you!!

The "quick and dirty" way would be as you say, just make all the minimums the same and see if that works.

The "right" way is to do the ESC calibration and neutral instructions on the wiki.
