You can edit the uav file in almost any editor. Windows Notepad is OK. You might even view it in html if you click on the file.
Actuator settings: make more conservative (So that the servos don't go zooming, perhaps the wrong way in Swash Leveling routine)
1350, 1522 , 1750 or 1750, 1522, 1350 for the cyclics [0,1,2] maybe tail, [3] too.
Throttle curve: -- yours has throttlecurve1=throttlecurve2 (gotta have curve2 for negative pitch)
put this line in for curve2 in place of the one you have:
<field values="-1,-0.5,0,0.5,1" name="ThrottleCurve2"/>
Manual Rates: 220 vs 540 (you want to see some movement)
<field values="540,540,540" name="ManualRate"/>
<field values="570,570,570" name="MaximumRate"/>
220 degrees per second (rotational rate) is a very slow flip. My heli would probably need 30 feet to invert. But at 540 degree / second t handles fine. If that is too fast then lower your TX endpoints. I use 570 maximum so that the heli can provide a little movement of its own.
Flight modes:
I see you are set for 3 flight modes. You can probably get 6 flight modes by mixing. Change flight mode in the air (if possible) to compare different settings banks--there are three--and different flight syles: Acro+, Vbar, Rate, Rattitude, Weak Leveling, etc. If you are using a Spektrum TX I might be able to help with mixing.
Let me know if you have trouble editing.
I hope this answers your question.
