Hi I have bought T-33 jet trainer and it is a very nice airplane, it flyes well. I also have the SAAB B17 and NAMC YS-11 from Inibuilds. But I have some questions: 1. how can I reset the G-meter 2. When using TACAN I cannot get DME readings on the DME instrument and no pointer is active on RMI, it works with VOR I did try with freeware Hawker Hunter and Justflight Hawker T1 and DME worked perfect and gave DME readings plus DMI pointer was active on both planes 3. How can I get into rear cockpit, ref to page 30 in manual. I have tried varius key combinations that works on other planes, among them SAAB B17 and NAMC YS-11 BR
