X650 Esc1 issue

Hi all,

I’m posting here since I saw a few similar topics on the x650 in this forum. My setup is a x650 build with a Pixhawk 6X and the stock tekko32 am32-flashed (2.20 F421) ESCs. I adapted the settings to a list I found on here.

Problem: I am able to arm, but do not seem to be able to spin up while esc1 is connected. The connection are on Servo9-12 on the pixhawk AUX channels, because of the IOCTL on that part. If I remove esc1, they spin up. I initially had a situation, before adapting the settings, where motor1 would spin up but less strongly, as motors 2-4. What was wisdom am I missing? Is it the sinusoidal power-up, or is it because the esc’s have been flashed and setup individually, and are not synced? How would I address that? Thanks!
