J-Bizz 200 Bugs, Suggestions etc.

The J-Bizz 200 works excellent in my simulator (FSX) apart for a few minor flaws.
1. J-Bizz "Skydiver" configuration:

The inside parts of the door (the stares) are invisible.
When the door is closed, the outside parts of the door are visible and the interior parts are invisible.

(note the invisible stairs).
2. Although it already looks excellent, I think the engines should look a little more seperate - meaning having a tube for each. It's just a personal opinion, but thought I'd post it anyway.

3. Systems:
It seems to work well, with a few exceptions:
In addition, I ran out of fuel around a minute after takeoff (my engines were working at 100% and I climbed around 40,000 ft. in a minute
).
Since refuelling (when I ran out of fuel) and arriving at Edinburgh I used only around 23% of fuel.
I didn't track my speed so I have no idea if I was supersonic or not.
Cheers!

- The autopilot speed hold doesn't work
- The ILS approach system doesn't seem to work
