This is my first multirotor and it's almost perfect.I've made maiden flight today and my hexa (from jdrones) is oscilating a little bit (faster). It's almost when windy (a little, too). I'll post a video soon, but reading wiki, i saw that i must change RATE_ROLL_P and RATE_PITCH_P.....how to much i need to decrease during tests? The default on firmware 2.0.49 is 4.6...lets say, 4.5 and test?
I don't have telemetry yet, so i need to land, plug usb and change.
I also noticed another thing: i'm doing some tests in my bad, holding my hexa with motos on and about 5cm in the air. With default settings, using telemetry by usb, i click on "Flight Data" and select "Tuning" checkbox. In this graphic, i can see all 4 lines moving in the original settings. After changing P for stabillize pitch & roll from 4.6 (default) to 4.3 (i'll try tomorrow), the lines nav_roll and nav_pitch doesn't move anymore, stay in line, even moving my hexa. This is right?
I've just changed P settings and clicked on "Write Params". Is safe to flight? i'm planing more tests tomorrow.
APM 1.0.84 and FW 2.0.49
PS: LOG files attached. first before change, second after change (you can see lines not moving)
Jonis, for original jDrones ArduCopter HEXAs with bigger motors good starting PIDs are looking like this:
Those values are good starting point to make your finetunes.
