I would be interested to know now the one tune works compared to the other.
Two main things to test:
- fast forward flight in Attitude mode holding a significant amount of forward stick. Suddenly release the forward stick to where you are only holding a small amount of forward stick. Does it "pop up" as if you gave it a lot of back stick?
- descending straight down, no wind, at slow to medium speed. Does one hold attitude better than the other and not wobble all over the place?
