QPlane first flight, yaw needs more tuning?


(hans bert) #1

Hey Guys,

i did my first qplane flight a few minutes ago, 3.9.0 pix2.1. I was almost pieeing myself :smiley:
Yaw was not very stable, so i added 2° angle mounts for the motors prior flight. Now its a bit better.

Transition VTOL->plane was ok, but took a bit long what to you think?
the yaw to the left was due to the motor torque. Maybe make the trottle up more slow/smooth any idea?

Transition plane ->VTOL looked good but than an unwanted yaw rotation :confused:
looks like one motor saturated, on 1954 (why not Q_THR_MAX_PWM 2000 ?)
Would be awesome if you could have a look at the log and give me some advice on yaw and on general !
Maybe i add 3 degree angle mounts, because hover looks quiet good i think.

@tridge thanks for your awesome work :slight_smile: i follow you since Samba and i love rsync !

that is how i mounted my angeled adapters.

thats what i try next. Can somebody confirm that i dont have a thinking error?

I stole the idea from here: http://wiki.mikrokopter.de/en/AngleAdapter

Changed the motor mounts to the second “dual angle” mounts. and did some hovering:

authority is mutch better from my feeling but PIDs are off now.
Hope my interpretation is right.
