Great project!
I made the 5F flyable too and have added the RPK-17 but only used the stock skin.
Weapons in French service were very basic:
MATRA rocket pods (usually on inboard stations )
LAU-32 rocket pods ( outboard stations, for training )
Slick and retarded bombs, 250 and 400 kg, French SAMP series and Mk82 , two in tandem on centerline and RPK-17 fueltank/bombrack combo which can hold up to 4x 250 kg bombs
The Dassault 5F promo picture also shows AS.30RC , centerline station, but I dont know if this was used operationally
5F never got RWR
A2A missiles.. I cant remember the details, they had none at first ( main mission purely A2G ) but I think they were modified later for AIM-9B/F or even Magic
BTW, check the fuel capacity value of the RPK-17 data ini, the BFT-type tank is working correctly since November2009 updates ( or one update earlier, cant remember ) but the old editor always deleted the fuel
