Solved, there was a conflict with m4fire and m4aim command. Deleted all binding related to the m4 and now I can use as usual f10 map.. now I can't shoot no more from the copilot seat with the carabine not a real issue...
arrived and easily installed on my ikea chair! no issue at the italian custom....
it's a great piece of gear! a real game changer for heli simmer! tried on fs2020 (h145) and dcs modules... perfect!
thanks again...
