Everyone does remember HiTech is reworking the damage model for the next release? Something about increasing the number of damage points.
Last week I flew an offline experiment that is easy for any of you to duplicate. I set ammo to 10x then upped a K4. My goal was to fly in-line behind the cons 75- 200yd back with full zoom to watch the damage from firing one 30mm at a time.
B24 - I began at the wing tips working in starting from the left. Until I hit between the two engines only pieces like ailerons fell off with football size flashes. When the outer wing panel with engine fell off the inner engine or wing might begin burning. If you hit just behind the inner engine on top of the wing you get a fire. I changed to the right wing tip with the same results. Because the fire and smoke from both sides remaining wing stubs were obscuring my view at 75d-200d I then used a single 30mm to break off each wing stub clearing the fire and smoke. Using single shots I dismantled the tail section. Single shots broke off the rudders and stabilisers. Then single shots broke each half of the remaining rudder and stabiliser "H" from the fuselage. After placing 5 single shots into the aft body section behind the wing root with no visible damage, I placed one round into the wing root exploding the B24 fuselage. By working the aircraft with single shots it seems you can map the current damage points.
P51 - Working from wing tips in, ailerons fall off then either a wheel assembly or flap falls off or the wing snaps off. The rudder and stabiliser break off easily with single shots. The aft fuselage section absorbs rounds. Hit forward into the wing root and the P51 explodes.
190D9 - Similar wing damage to the 51 but you have to be much more precise in shot placement. Almost seems like hits don't register unless you hit very specific small areas on the wing. Tail section and aft fuselage the same as the 51, but again your shots need to be much more precise. A single 30mm into and forward of the wing root explodes the 190D9. Cutting the D9 apart one 30mm at a time required very precise placement apposed to the B24 and P51.
P38 - Working from the wing tips in you had to be very precise and land hits on the surface planes of the wings not into the trailing edges. Ailerons would fall off to a single will placed 30mm. The outside wing panel would fall off if hit on center just outside of the boom. The booms did not destroy hitting in the aft. The tail section needed precise shot placements onto surfaces, not edges. Hitting the booms in the forward section most often caused flame and smoke. Hitting the inner wing sections and pilot pod on center cause the P38 to explode.
