S550 on board Power distribution accurate?

i am using s550 frame and readytosky 40A ESC. i have 920kV motors and a 3s 5200mAh battery. the motors and ESCs are perfectly fine, checked them on a quad, but as soon as I solder them on this hexaframe, the servos don’t give out constant output and even after ESC calibrations the motors don’t start up in sync. i even used DJI Naza m lite and even in that this issue is there.

Don’t multiple post.

Under what conditions are you testing this?

sorry for posting it multiple times but I am in dire need of help.
initially I used pixhawk 2.4.8 and in all the flight modes the servo output of 3 motors was way lower than rest three. even after multiple esc calibrations it wasn’t resolved. checked the ESC on a quad build and they are perfectly fine. Changed the FC to naza and still the same issue

Many say that.

I’ll ask again:
Under what conditions are you testing this?

5

conditions as in, i am a complete beginner at this

6

Is this on the bench w/o props? Is the Transmitter being used?

7

yes. and i also did a test flight before this where the drone took off spinning and crashed. it was ocsillating and went completely out of control.

8

Then the test is irrelevant. Use Mission planners Motor Test to test motors.
Flipping on take-off is almost always caused by the wrong motor order or spin direction.
As a complete beginner you should use The Methodic Configurator:

i did use it and made a quadcopter. it works like magic. but the moment is shift to this hexa frame, stuff starts to go wrong

10

Well then do it again for a hexacopter.

11

i did… :weary: but the servo output showing on the screen is not equal and I am scared to test it and crash the drone as I am at a location where these parts don’t arrive quickly either

This is nonsense if you are using the transmitter. Remove the props and use Motor Test. If the motors start at the same throttle % (roughly) and spin at the same speed with increasing throttle percentage quite crying and move on to the next step which is to confirm if the motor order and direction are correct for a Hex. See the illustration here for the Frame type you have:
Motor Order

i have used the exact same components and made a quad copter. the moment I use S550, there’s this motor issue. does it have something to do with the printed PDB?

14

So you are not following this simple advise?
Good luck.

dude??? i have the hexa X type frame…and sorry if it felt like I wasn’t following your advice…did not mean that…
