I'm not really qualified to give advice on a pony..or any other plane
..but here goes.
1) The pony is an E fighter so it won't out turn a majority of the planes in the game (190 is only exception).
2) It operates better in the vertical than in the horizontal.
3) It's 6 .50's pack a great punch..but only at point of convergence...
SO...
1) E fighters need to be employed from a position of advantage..dont engage higher bogies if possible..climb at an angle 90 degrees to fight till your co-alt or higher.
2) use shallow dive and wep to maximize e at merge. Try and "bottom out 1500 under bogie at 2000 or so and begin gentle climb to merge.
3) if bogie goes nose down to HO apply rudder and pull up gently to vertical. You now "on the perch" and can prosocute attack from position of advantage.
If bogie stays over you..thats a warning sign..If he extends use low G climb to reverse..if he starts a gentle climbing turn..drop the nose and run for help.
On offense...use the ponys vertical manuvering and E to rope your opposition..you need to be wary of 109's (G6&G10) since they outclimb,outturn and out accelerate you (same for La5) and 190's in the vertical (combined roll and acceleration in dive make vertical scissors losing bet) Most others you can use low G zooms to gain advantage on.
On defensive your weakness is your slow acceleration and poor sustained turn rate..so..
Never let pony under 225 IAS and never initiate a turn under 5k or so with other bogies around. Always have a 2k advantage at start of attack and work down to bogies level..dont go under bogie till your more proficient..one good ploy is dive in and level 500 over bogie...begin gentle pull up bout 1500 out if he slow and goes nose up..pull straight up and chop throttle, if you time it right you'll drop right on him..you'll die if you misjudge his e badly.
If he pulls up and has e continue in a shallow zoom climb ...if he gains you're now the grasshopper
...if he starts to fall back
pul up to maintain seperation..idealy you'll stall him out 1500 ft directly under you..
Hope this helps a bit..just remember you got this from a grasshopper
