K4 Climb Rate Vs IX

[MAD-MM]

There was last Year long Thread about K4 Climb Performance, first it was to high the chart's was to low because of missing Exhaust Thrust after that i dont realy rember what our K4 now actually has.

After the Spitfire lighter Airframe with his Merlin 66 prove a impressive climb Power on Sea Level (4600 Ft/min dont know how correct this is)

There on same level or have we noticeable differents?

Please i dont ask who build the best airplanes!!!
