Dang! I also would like the source code files if possible. I'm working on the KA-50 MFD's tomorrow. I'll be altering the following Avionics files:
hm_avevn_ka50.c
hm_dam_ka50.c
hm_eo_ka50.c
hm_eo_ka50.h
hm_mfd_ka50.c
hm_tgt_ka50.c

I guess we can merge yours with mine after you get back from your Holiday.
