one motor is not synced

[itayk]

Hi,

I'm building my first drone, using Naze32 controller.

When I log in to baseflight, in the motor tests, all the motors start at the same speed and it looks fine.

When I'm using my Flyski i6 remote controller, one motor is legging behind (receiver connecter through PPM).

I did ESC sync for all the motors, calibrated the drone, but still, nothing helps.

Please help me.

Check your escs using blheli make sure it sees 4 escs, if that checks out it could be a min/max throttle settings either in betaflight or blheli.

It sees 4 ESCs, and I updated their firmware. But still the same issue.

This is what happens when I just moving up the throttle:

It's weird because I replaced the Flight controller and it still the same behaviour.
But when I do a manual test from betaflight (without the receiver), they all spinning the same.

Any ideas?

is it all ways the same motor giving you problems? did you try swiching motors 1 with motor 3? just to see what will happen. are all the conections good .. is battery ground solder well... go over you're hole build and check conections . when plug in battery dose the drone/esc make the correct beeping sound??

is you drone is angle mode when you turn on you transmiter? maybe it trying to straight itself out. it hard to tell from the video whats going on

All good concerns here.
Switching around parts, 1 at a time, can isolate issues. Re-flowing solder can improve bad connections.
If you're in an auto-level mode, it will act weird on the bench.
The fact it's not spooling up right off though makes me think it's a parts or soldering issue.
