Nobody else has any experience or advise with this flight control? Starting to think I should not have taken Josh's advice to buy this.
So much depends on PID settings and the best bet might be to start by clearing I and D and then bringing P up until it is unstable and then backing down 10%. Then adjust I and D to filter out overshoot and wobble.
I browsed this thread because I wanted to find some PID settings to get me close on 4S with a Versacopter like quad. It works out-of-the-box with 3s (and very well). I'm going to have to take my own advice and start from scratch, I believe.
EDIT: This morning I put I and D at min on all settings and then put P at 10 on all settings. That allowed me to fly. After some fiddling, I backed P down to 7 and right now I have D at 10 and I at MIN. This is with a QAV250, Luminier 2208-9 motors, 4s 1350, 5045 props and 20A escs. I am not tuned but I can reliably fly it. In Attitude mode it is probably good enough, in Rate (Acro) mode it needs a little work - probably more D. It will punch out reliably in both modes. As always YMMV (Your Mileage May Vary).
EDIT2: So... what I learned while flying. Damping and Power2sens interact with the PIDS - a lot. So does Roll Factor % and Agility for yaw. So not only do you have the normal PID interaction, there are four other factors that come into play. My current PID setting (which is getting closer to OK) is Roll/Nick

20, I 5, D 10, Damping 0, Power2sens: 60 (check out the specs on the quad above). Still not tuned great but quite flyable. I arrived at this by setting I and D to MIN and then upping P and decreasing Damping and Power2sens until I got what I imagine to be a reasonable figure. Then increasing D until I got crap and backing off. I is just a guess - I couldn't detect a rise when pulling back at half throttle in Rate (as described by the manual) but I added in 5 just because. YMMV I left Roll Factor and Agility at factory settings but I'm sure both need to be adjusted.
To some extent, one might be able to leave the factory settings as is and adjust Damping, Power2sens and Roll Factor only. Just guessing but the interaction of seven different values is somewhat confusing. Still - I like the receiver so I'm pressing on.
