Last night I was flying the G2 and F4, prepping for the upcoming FSO, and was having a hard time with the flight model, especially of the G2.
The F4 is a much easier bird to learn than the G2, believe it or not. The G2 is very well suited to a sort of mid-level, mid-speed E fight whereas the F is more suited to "entry-level" stall fighting due to the softer breakaway and easier recovery.
Comparing the two, I'd simply recommend you fight the F like it was a Spit 9 and fight the G2 like it was a Yak.
Another question, I thought the G2 would be able to take an F6F in a stallfight but had one hell of a time last night - albeit the F6F was flown very well and I was in a bird I never fly - but shouldn't the G2 be able to handle the Hellcat?
At low speeds with flaps out and proper trim, the F6F will be a handful for a G2. In that sort of situation, your best bet (as is the case with any early-early, mid-mid or late-late 109 vs X match up) is to use your superior power to weight ratio to gain a vertical advantage. The F6F has nowhere near the G2's ability to add E through acquiring altitude - during a fight.
Off the cuff, using that G2 v F6F match up, I'd offer the following:
1.) Take the fight into the vertical as soon as possible. You will gain energy rapidly and, should the Hellcat elect to try and follow, he will lose energy just as quickly. The fight can go from even, to heavily lopsided in your favor, within the space of about 10 seconds.
2.) Trim tail heavy. Combat trim seems to be especially troublesome on the 109's in stall fights. It limits your ability to bring the nose around in both the vertical and horizontal plains and will fight against the port leaning engine torque (which is an advantage once you learn to use it).
3.) Once properly trimmed and fighting in the vertical, it should be easy to bleed a heavy, underpowered AC like the F6F, of any E advantage - and hold it for yourself. Once a position above the Hellcat is obtained, the G2 has an uncanny ability to hang in the air with proper throttle management and careful use of the control surfaces. Ill try and type out a visual...
Imagine yourself in a lazy rolling scissor with the Hellcat. After a few rounds, you are both slow but you are on top.
Continue trying to claw altitude by weaving back and forth above him. This will put you in a risky position and you must carefully judge the Hellcat's E state to determine whether he has just enough E to get guns on you - or just enough E to bring his nose up in desperation (read: no shot).
When the 109 starts to become unstable, apply full rudder right, full aileron right and ease up on the throttle (flaps out goes without saying). While reducing throttle in a climb sounds downright stupid, it will keep you level and stable by reducing the high torque/light airframe relationship between the DB605 and the G2 tub.
All this time, you should have the ability to rock your wings, while weaving, and get a visual on him, just below you.
When you see his nose begin to shudder and drop below the horizon, he's had it and you are now in complete control of the fight.
Apply full left rudder, full left aileron, slight back pressure on the stick and jam the throttle to WEP.
The combination of these factors will, almost within the space of your aircraft, snap roll you around, using primarily the engine torque, and if youve done it right, youll get a clear shot at him from about 150 yards and can rake him from nose to tail.
Once you see that shot coming, ease up on the throttle again and reduce control surface input to regain stability.
Shoot. Boom. Rinse. Repeat.
The entire engagement shouldnt last more than 20-25 seconds.
