the D11 certainly "feels" the lightest of the jugs. only its anemic climb and acceleration cause me to choose the M over it, but even still I take it sometimes just because.
get in a nice full flap wallow fest on the deck and if you fly the jug to its full potential the other guy will very often either just run out of fly and auger, or will give you the passing shot you need, which with 8 50s doesn't need to be much for very long.
its not a VERY agile aircraft, but it IS more agile than most people expect, which is where its lethality is, all to often the other guy assumes you cannot match his turn or manuever and by the time he realizes his error, hes in the tower still hearing the hit sounds for several seconds.
2 tips:
1: unless your going on a dedicated bomber hunt, take the light ammo load 8 gun pack, it gives you a little extra climb and overall maneuverability, which in a jug can mean the edge ya need, and you still have over 2000 rounds, more than enough to shoot down a couple sets of buffs should the opportunity arise.
2: if you take 3/4 or a full tank, make sure you switch to the main and leave the AUX with a 1/4 in it. the jug (in AH) is notorious for getting main fuel hit, and it drains QUICK.. and its pretty much a death sentence unless your at 20k or right next to your base. Oil on the other hand.. you have the middle east in your plane, she will go several sectors with an oil leak.
