decide on a style you enjoy. pick a plane (and most prolly a side) which corrosponds with this style. -thers manouvering type planes, speed planes, accel planes, alt planes. essentialy boils down to do you like B&Z or T&B but its a little more complicated than that i think. heres a few play styles for the planes i like to fly (fw and bf

)
Climb rate, acceleration and manouvring while you point your nose up =bf109 series. the earlier ones (esp f2,4 - g2) are very nice to fly. later ones can prove frustrating for a less experienced pilot as it will seem that red team outclasses you badly at times. youl want to push for the alt advantage at all times as you can climb better. very irritating high speed performance but you learn to love its acceleration which allows for some fun dogfighting.
Speed, speed, speed, dive, roll rate, armour and weaponry=FW series. they all ****ing rock. you will need a wing man though so that when you break away in a dive to avoid someone your wing man can follow and clean up. otherwise its extend till you can turn over and go for a head on. roll rate means excellent scisoring (look that up on the internetz. vey useufl manouver) but youl bleed E quite quickly attempting any conventional turning at all.
Russian planes in general. manouvers, dogfights, turnrate, very very good low altitude performance. esp the late war LA series and the like. fairly poor at higher alts.
Spitfire is a very enjoyable plane in general. kind of the 'middle gruond plane' that is great at evertying amazing in nothing. fast, manouverable, good alt performance , the works. i dont fly it at all but from what i can tell its good enough at evertying to poke holes in the weakness of anything. thats the way it seems in a good players hands anyway. otherwise it just does lots of zooming around and turning and shooting things in your average spit noobs hands.
Fly the mustang if you like your flashy looking planes i have no idea how to use it all i know is that if it kills me its cos it was flying just out of the earths atmosphere and dived on me with its stupid stupid guns that never get a kill but ALWAYS break something that you needed like cables or your target

.
Choose a plane style and learn it first. otherwise youl prolly ge tbogged down with all the different planes and how to fly them and you wont get good enough with any of them any time soon i guess. gunnery is v impt to learn as well. theres some tracks out there somewhere that are made just for gunnery practice but i cant remem where from.
I dont really have experince with much else but thats jsut my experiences im not flash as a player but these things seem to work. hope i helped any first timers out there get started off

. btw any FW players out there wanna share some wisdom

always looking for any advice myself to.. esp whens the right time to zoom climb? to what speed do you push it?
oh yea. one last thing. if you are struggling to get into and enjoy the game. get a few friends to play. you ehh.. dont need a cd key so.. may as well let them borrow it ... just to play ya know.. on lan or something...not illegally.. and play a few games together. always fun playing with other complete noobs. makes for a few laughs and a good time. my early resentment of the spit as a previously dedicated 109 flyer started when i hit the ground at 100k and blew up while my friend flew into my newly respawned view at about 290 in his spit hit the runway at more or less the same speed and bout a 45 deg angle and despite loosing everything except his cockpit managed to jump out and run away from his pretty unrecognizable spit. damned spit h4x -_-.
