Step 1 I'd recommend practising figuring out the slowest speed you can take the flanker vertical I don't know what it is off hand probably around 300kts. figuring out the slowest speed to go vertical is key in bfm rarely do you want to get below this speed. If you do it should be to get the nose on for a shot otherwise you'll need to unload <1 G to get this speed back otherwise you'll be sitting waiting for the eagle or big mouth viper to climb above you and club you like a baby seal. Just to touch on the one problem of the eagle being above you remember if you both go vertical the objective isn't to out climb each other it's a one circle fight or nose to nose fight so you want to max perform to get your nose on him first this. The bandit will have to react and you may get a brief archer lar or try a snap.
Keep the Eagle in the 0.8-0.9M region her wings will thank you for it, bleed down for angles (nose on first) if necessary. In this speed regime you'll be rating like a bat out of hell not much can match the Eagle.
