I have an early FY-90Q basic not pro but after following the instructions here http://www.rcgroups....&postcount=1813 I found it will work just fine. All thats needed is to download the software from the FY website and connect a USB to TTL converter to the FY-90Q. The settings for me were all way too high causing the quad to swing about overcorrecting all the time, worst in a wind and at low throttle. After backing off the settings I have much more confidence in it and will now start testing with a camera on board
If anyone else like me found tuning the pots didnt do the trick then this may help.

I use the USB to TTL onverter that came with my Remzibi OSD so didnt cost me anything to try

Case in point. Back when the FY-20A was a new gadget I contacted them and asked if it supported PC access for firmware upgrades and tuning. From their bewildered response I gathered that they did not understand why anyone would need it. Fast forward a year later and the FY-20A still does not have this feature.Or maybe it secretly does.

If you stay tilted for a long time fighting a steady wind (or simply flying forward for a long stretch), the (rather simple) algorithms that calculate the attitude presume that you're flat and the tilt information is sensor error, and start compensating for it.

Attitude control is OK for photo as you don't care about doing smooth movements.

Using no self leveling as you say would sort the problem out but the other FY20 and such dont seem to get confused like this do they? unless this is linked to the intermittant diving problem I have had with the FY-21!
