Hi.
i was watching a few vids today of b52h , t/o landing,bombing,cruise , on one of the vids it gave a close up of the nose section , and it gave the crew weight 5 crew at 1500lbs , so my 220 lbs as now been amended to 300 lbs per crew member.
I have also read that the b52h at full weight is capable of doing 6000 ft min climb after gear and flaps retracted up to 33000 ft in a tactical climb , but normal rate is about 3000 ft min , they then level off till some fuel is used  , before climbing to between 50 and 55000 ft.
I could at one stage match that , but my last effort , was a mess , but i dont give up that easy.
As for air files , i have no programe to edit these , nor do i like to tamper with them , understanding the SDK for the aircraft.cfg or panel.cfg , and repainting aircraft for fs9 is my limit.
I had a quick look in the b52 panel.cfg ,to see if i could swap my co-pilots inop alt , but FSX inst panels are getting imposible to workout.
regards alan.
p.s. i posted my camera views,in the camera view post some one had started,they work well for me,but i have done a slight change since,in my aircraft.cfg file,the title for aislestand/overhead , now says engineer flight,and the engineers now has rest position after it.
