ka-52 is a beautiful aircraft... to remove counter-spin of the helicopter, the designers have wonderfully used two counter-rotating main propellers thus removing the need for a stabilizer properller at the back of the helicopter... simple idea.
but the kamov design office should now move towards armored vertical take-off and landing "tilt-rotor" gunship aircraft like v-22 "osprey"...
in fact, one step ahead, like the "vtol-x" program...
