To me this is the apex of the game. Taking on rides that are far more capable than mine and finding a way to win.
It is just a conspiracy of mind!
Yes uber rides have more options. Great feedback in this thread though on dealing with them. If you have to engage and don't have E or alt try to force the uber ride pilot to make a mistake. If nothing else to give you time and extension.
Heck if nothing else when he is on your 6 cut the throttle, slam the rudder over, turn hard (basically speed breaking) and let him fly past. Take a shot if you get one. Don't expect to get a 2nd chance on that technique though.
Still on your 6? Dump the flaps and fly in between the trees. These things I do but I avoid stick stirring (just my thing = too gamey for me). If you are still alive
TAKE IT TO HIM! Uber ride dudes don't expect this sometimes. This is a mistake on their part.
If he is using his superior climb and acceleration at this point to position for a last killing pass...use it against him. You may have just enough E to turn your nose on his (or part of his fuselage). Dont bump your nose until the last split second. He may think you do not posses the E. What a surprise it is when he discovers you do!
EDIT:
Greebo is a master at this BTW. Like no other. When you think you have him (or so out match his position) he finds a way to even the odds and even kill you. He is amazing at this. I have learned so much by being killed by Greebo.
