In rare cases after arming throttle level is higher for a second, then goes back to normal values.  
I noticed it first time when I used 1.7 firmware, however there is similar topic from previous year [Slight higher idle throttle when first arm?](http://discuss.px4.io/t/slight-higher-idle-throttle-when-first-arm/2471) .  
Hopefully I have a log [Flight Review](https://logs.px4.io/plot_app?log=7c0b159c-bf28-48dc-8677-b3ccd1c2d25b) .  
I’d ask someone to check the log because I want to be sure that copter can’t apply too much throttle on startup.

In related issue was mentioned that MPC\_THR\_MIN could affect but after I lowered the parameter nothing has changed.  
Maybe I will fill the bug in Github shortly.

Sort of: switched back to Ardupilot.  
Here is the (closed) issue: [https://github.com/PX4/PX4-Autopilot/issues/9022](https://github.com/PX4/PX4-Autopilot/issues/9022)

What do you mean? That you did not solve it and therefore you switched to Ardupilot?
