I think my roll PID needs adjusting. Unfortunately I can't take my PC to the field so I'm hoping someone could suggest an adjustment to save me many trips in the car. :)
I'm currently using Chris' default Bixler param file. My Bixler weighs about 1.1kg. I changed the loiter radius to 30m.
If you watch the video it does rock a little in STAB mode after takeoff, although it's when it get hit by a side on gust of wind during the Loiter test that it really goes wild. I wish I'd let it recover by it's self, but I was so shocked I switched straight to Manual, sorry.
Generally it flys fine, it's only in gusty wind that the flaw becomes apparent. Maybe it's the I value that needs adjusting?
Thanks in advance for any suggestions.
Maybe move your aileron control horns out one notch?
