First off. The only time i have been able to harrier onn g2 is inverted with a 330 or the cap and that was after a ton of changes to the plane. Havnt tried the aero works profile tho. You can use g2 to get your bearingl with hovers and t/r but dont try too hard with the other stuff.

I have not personly flown a magic but, yes you will probbaly need to blip the throttle some more to get it in the sweet spot. Set your cg so that when you roll inverted the plane flys strait hands off. That will help. Spoilers or flaps will help a little too. All planes are diffrent and are set up diff too. You should be at 45deg in the harrier. Its hard to say though. My sig se will harrier at a low aoa and low throttle but when i try to get the nose up it rocks like crazy. My omp 540 profile will hover at 45deg all day. Still need to be on the sticks a little but not as bad as the se. My little bat is way too easy to harrier, and can do so at any angle.

You pretty much have to play with it and try diffrent things to see if it works. Good luck.

Hope this helps
