you misunderstand me. all three to be used effectively need a bit of skill. unlike in a tempest which u can dive in a 600mph and have the plane push itself back up with no compression problems and 4 20mm hizookas that with a few well placed rounds will take down any aircraft. even the spit14 when used properly at altitude is a helluva plane to reckon with. this conversation should be about lowering the perk of the spit14 and not lowering the eny or perking said 3 rides. put a new player in a tempest and then a 51. see which he lands kills in very easily and which he dies in more often. a spit 16 is very easily outflown and i only have trouble in my 51 against a veteran in a spit 16. the La7 also can be very easily beaten unless the pilot with the higher skill flies the lala also and so said with the 51 too. none of them need to be lower eny theyre perfect as is.
The Tempest is more of a challenge to fly than the P51D. The P51D is far more forgiving and more versatile. The Tempest if fast, sure. It hits hard, sure. But it inst the most maneuverable plane out there. A new guy is going to have an easier time in the P51D, imo. The Tempest isn't a plane to hop in to a just fly. The P51D is. In the Tempest, managing the torque, right turn, rudder, and raw speed isn't a beginners treat, it has more quirks than the pony. The P51D can go either way and is far more stable (forgiving). In the hands of a vet, sure the edge goes to the Tempest. Matter of opinion, I know.
I like the self scoring on how you defeat other aircraft. Remove the pilot, compare the actual ability of the aircraft then the "newb" variable is non-existant. Take each category for what it is worth. The La7 is a better bomber interceptor/hunter (especially low level) than either the P51D or Spit16. The P51D is better at escort duty and ground pounding. The Spit16 is more capable at dogfighter than either the La7 or P51D, both find themselves out-turned, out rolled, and out-climbed, and will eventually have to run like they always do but even then the Spit16 can hang with them for a bit because it accelerates and retains E very well.
Lastly, I wont argue that the Spit14 needs its perk reduced. There are a whole host of aircraft that needs to be checked both in ENY and perk price. The list is getting too crowded at 25+ ENY, and too few down low, IMO. Start down low at 2 ENY, bring some of the 15 ENY down to 12, etc etc. Space 'em out a bit more.
