Yes switching to 3D worked, many thanks!
AC was a BC so cockpit was wide enough, also the up/down keys worked but not left right so think I had messed up something in my novice fiddling.
Being flying FSX for while so thought I'd try x-plane and well really nice. Tried the SR71, wow crashed twice on take-off but third time pulled at 180 kts and away she went, mmmm tricky little filly.
BTW if anyone interested running it on Q87M-E, i5-4670, 8gb ram and tweaked BIOS to give dedicated 1GB to HD4600 and runs really well.
Again many thanks imk
