HI Guys1

I installed the version 1.1 on top of 1.0 and instead of improoving i had huge problems. The first one is that VNAv still dont work at all but the main problem is about the LNAV. I take off i engage autopilot I engage LNAV and VNAV With VNAV the plane climb like a rocket and the speed doesnt rise and LNAV doesnt follow the rute make a turn in a big angle making the plane fly upside down. On 5 flight all 5 the plane crashed after take off..Any idea?

Thanks
Alfredo
