Completely wild idea - and you are tasked with trying it out...

Force your fuselage angle to -90 degrees, and engine type rocket - with enough thrust to overcome the model's weight.

Your gear contact points would have the same "-Z" value, with x- and y values spread around in a triangle so it doesn't  tip over. 

If the contact points are z,x,y:

-10,1,0
-10,0,1
-10,-1,0
-10,0,-1

would give you four contact points,


My main assumption is that the flight sim engine assumes that the fuselage angle defines the "line of thrust".

I believe - and you'd have to check the SDKs - that engine type "3" is rocket.  However, come to think of it, I don't know if it's recognized in FS2002/2004, and it's just a CFS2 thing.

If not, just make it a very powerful jet anyway

I recall seeing (awhile back) a complete package for the shuttle Endeavor, or one of its compatriots.  The full model, with the tank and boosters, started from an upright position, so I would look around and see if you can find that, then work off it.
