Having good success with AdruPlane V3.1.2beta1 loaded on my HK Falcon flying wing. Did a couple of tunes today, then tested fbwa, stabilise, and a short auto mission with no major problems.
What I do wonder about though is how auto_tune functions in regard to increasing or decreasing the Autotune_level parameter and then repeating the autotuning flight. Does decreasing the tune level parameter and doing a retune result in a softer tune, or once peaked up by a previous tune do the PID's not drop back again ?
The reason I ask is that I did a tune today on level 7 initially, and got a reasonable tune I thought, then later in the day I set the tune level to 10 and retuned to see how that went as well.
The result was good at cruising speeds, but I discovered that in slower gliding that the plane oscillated in pitch and roll.I'm not sure if the level 7 tune did that but I think it didn't.
I'm planning to retune at level 8 and see how that behaves, unless anybody suggests that is not going to help me...
