Update: Kamov Ka-50 DDR [EHCS]

Changes:

Adjusted missile flight behavior: Missiles now use the helicopter preset and no longer loft into high altitudes unnecessarily.

Reworked missile rack: The rack now more closely resembles the original 9K121 Vikhr rack.
The color scheme has been updated, and the number of missiles per rack has been increased from 3 to 5.

Fixes:

Missiles can now correctly receive a laser code via the EHCS standard before launch.
This was previously not possible due to an issue in the original missile by Anonymouse Sandwich.

Note:
There is currently no option to manually set the laser code via the pilot interface or in the editor.
To change the code, you must send the desired laser code to Channel 4 of the "Target Data Passthrough" node on the EHCS controller.
