xinmayu,

I flew the 225 for the first time this evening.  Nice airplane - and big, really big.  I flew it with the 747 panel but there is also a 225 panel with six engines that I just now installed.  I haven't flown with the new panel yet but it looks pretty good.

I found the panel at the same site where I got the plane.

As far as the engine exhaust goes there is an install.txt file that explains that fs9 only recognizes 4 engines.  The builder tied the two outboard engines on each wing to the middle engines.

So even with the new panel and the six sets of engine instruments you are probably still only going to get 4 engine exhaust trails.
