Hello there ! need you help :-)
got 2.2b4 Version on my Quad.
All fine : take off - stable
fly a bit - and suddenly when i want to change direction :
- yaw stick movement leads to oposite reaction....
Once the quad also started turning around 120 deg.
verry strange i know :-)
- Hardware is correctly set up and i can't find any reason for this strange behavior.
Any help is appreciated !
I also saw this, with 2.1 and now with 2.2, but I think it's because the magnetometer offsets have been reset during upgrade and it needs more time to settle. Does it get better if you try flying longer? (And I think magnetometer offsets are only saved during disarm but not sure about that).
I also saw this when Yaw P (Stab yaw P) was not high enough to rotate, it moved a little in the right direction, then compensated stronger in the other - probably overcompensated by Rate Yaw P.
I have a similar problem with a helicopter. It seems to only do it when I command right yaw. First it jumps a bit to the left, then it starts moving right. Yawing left works fine, however.
exactly what I saw - I decreased Stab Yaw I, increased Stab Yaw P and it was gone... it always yawed ok to the left but not right :-)
the stange thing is that it flyes stable with all other axis. I've replaced APM and Magneto....
do you think it can be the GPS or the 2.4 GhZ receiver ?
Check to see if all your motors are totally straight.
all super straight....
- wold it fly as stable otherwise ?
tons of thanks !
So you're flying in Stabilise mode? Increase Stabilize YAW P and try - really. It will work ;-)
got latest 2.3 and still the same issue
YAW isn't working properly ; all other directions super stable.
could it be a receiver issue ?
receiver changed : same problem....
one motor was a bit off-angle ; now it's strait and yawing well !
- strange but true :-)
