I've always though opening the entire forward fuselage directly into the relative wind to fire the laser as being detrimental to a high performance fighter the Falken is depicted as being. I think that a more conventional approach; a retractable ball turret similar to the YAL-1, would be more feasible.
I have my Falken kit still in it's box unassembled. I'm not sure if I should build it or sell it.
