I think what stang, in his inimitable way means to say is that the turn radius between the two is of minimal consequence. however I believe the G14 is superior in a knife fight over the the G6 because of it's better climb rate and the 30mm option. I prefer the G6 though.
109g14 turns like 109g6. dont use WEP during turns (too strong)
I agree with storch.
The G-6 has a slightly smaller turn radius but the difference is almost meaningless, up to the point where we can say that it is almost identical. Therefore the Bf109G-14 is clearly a superior choice to really maneuver with when the fight becomes slow.
I still get routinely outmaneuvered and shot down by some of the better pilots flying US planes, which generally have a much larger turning radius than the 109s but is allowed to use maneuvering flaps over wider speed ranges. If there's one thing I've learned from those fights, its that learning to tame the behavior of the 109 caused by strong WEP such extremely slow speeds is the key to success in slow speed maneuvering.
Unlike the US planes the 109 becomes severely unstable when the speed drops down around 200mph during tight maneuvering, and its at that critical point where most of the fights are played out. The recent changes that allows the use of the first notch of flaps over 200mph is of great help to the 109, but unfortunately the plane is still abysmally unstable when compared to some of the other platforms such as the P-47 or the P-38 using the first notch of flaps all through the maneuvering.
A classic pattern of slow-speed maneuvering contest against those planes takes place at the first merge. The P-38 or the P-47, for example, will chop throttle and engage flaps at speed where you cannot. You will have to chop throttle and use extreme rudder control to match the decceleration. After that it becomes a contest of who drives his plane slower, turns it tighter, and still maintains enoguh control.
With all those series of loops and turns your speeds change up and down of that critical '200mph' point where your flaps are retracted and then deployed again, not to mention your throttle setting changes rapidly up and down up and down and up and down again. Every time the throttle is changed the torque kicks in very harshly, and you immediately feel the consequence of such powerful engine mounted on such a small plane. Every time the flap retracts you feel the plane wanting to just stall out instantly.
If you can stop the 109 from wobbling out and losing ground during that first critical merge, then you win. If you cannot, you lose the edge to those fat P-47s or P-38s, before you ever have a chance to really enter a true contest of turn where you have a chance to win.
