I have serious problem how to configure my tricopter (2.0.39). Roll and pitch are correct. Yaw(rudder aka tail servo) was incorect thus i reversed RC channel via MAVlnk (btw i don't understand why dip switches are not enabled anymore in ACM...)
Now the servo moves correct according to radio stick movement but when i do yaw movement of frame by hand servo moves incorrectly - by this 'correction' frame would start spin infinitely.
How can i reverse this?

I can confirm your solution is how I did my tricopter.
For those still looking or using MP 1.2.88 plus.
RC Reverse (RC7_REV)
Almost at the bottom of the advanced parameters list.
Thanks Palo.
It sounds to me like a compass issue. It took me a few times to get the calibration right.
Or motor direction or fail safes. The fail safes are only good once everything else is working. I would look at disabling them first, then check motor direction (no propellors). If it's trying to RTL when you turn off the Tx it will not rest but try to go to 100m first. You can set this FS to do nothing or land.
The check the sensor setting on the MP, and see if they tell the truth.
APM has lots of things to go wrong but lots of uses too.
Don't give up on APMs.
Cheers.
Make sure everything is hooked up correctly and you have calibrated EVERYTHING (radio, compass, accelerometer). Get the servo working correctly via your radio input first. If APM is not applying the yaw correction correctly then go to RC7_Rev and change its value from 1 to -1 or vice versa. If you don't see a change in yaw correction then something else is wrong. Make sure you have flashed it with Tricopter and the latest firmware. I just did a tri today and it was all reversed but I got the radio right then rc7_rev changed and all was well. Good luck.
How do you reverse the yaw on the APM 2.5 using the mission planner?
