That's adjusting the CG (Center of Gravity) in either the .air file or the aircraft.cfg file.

I looked it up for my Lear 45, and it says:

static_cg_height=4.41

This will probably have to be a little different for the 35 model, but just play around with it until you get it fixed right.

In case you don't know how to find this, its in the aircraft.cfg fiel at the very end of the [contact_points] section.  Just look for what it says above, and correct as neccesary.

Just out of curiosity, why doesn't the aircraft have any textures?

When I opend the aircraft.cfg file, it was already set at 4.41.  So I tried to set it at 6.41, but the model didn't move an inch.    Is there anything else that could be holding it down?

Well actually, it does have a few textures.  I've textured the landing gears (which you abviously can't see in this picture) and the fan in the engine.  I haven't done any major texturing yet, but that's my next step after I figure this out. 

The static_cg_height= value affects the static height when the sim loads & in Slew mode. You need to tweak the gear vertical position entries to match. Try increasing the values marked in red by 2. (-6.42 etc.)

the caution is that in some instances, where the pivot point is rotated, the texture mapping may be "off".

That's why I've seen the "model-texture-animate" being recommended.

I don't really want to give the impression that I favor one over the other - especially since I tend to texture last.
