October 31, 201114 yr Hi Fs Fans,I was wondering if you need to be registered on IYP in order to use ALL the aircraft besides the C172. Like, after you use the C172 and you like the programme, you register, but you need to purchase a registration key to use all the aircraft, but I want to do it without paying.Is there way to do it for free?Thanks in advancetowerdudeP.S: Sorry for the double question. Just answer one of them. towerdude
