I noticed this the first time I flew this plane. It's not that the nose is heavy (well I suppose it may be a little), but what I think needs fixing is the CG. Normally when you give a plane up or down elevator input, when watching from an outside side view the airplane should pivot around the CG, normally this is 28-34% back from the leading edge of the wing, centered on the fuselage. Well in the 162 the CG is WAY too far forward. The airplane seems to rotate on a pivot just behind the cockpit, not even near the wings. This is NOT GOOD!!!

What I think has happened is that when the first piece (say the nose of the 162) was imported into OPS to replace whatever plane was used for a template, it was positioned much too far back. I've done many new planes and jets, and have seen this happen on my own. The way to fix this is bring the entire model forward (must do this in 3DS Max, or AC3D to change the model's origin) until the CG is where I mentioned above. I wrote to Roadtoad and Panzer when this model was first released but apparently they must have thought I was nuts or something.

I feel strongly (after experiencing this myself) that doing this to the 162 would take care of this obvious problem.

Pete, the plane was a little nose heavy, but as you said not THIS much. Could you possible fix this for me? I have no AC3D or MAX. It would be greatly appriciated.

Was it nose-heavy, or did the engine push it down? Or both?

This is beyond me right now. I've got many projects going right now with work and am unable to. I'd thing if Roadtoad or Panzer can ever get around to it, it'd be good for them to fix it up since it's their baby.

You are kidding right? I can keep the 162 right on the edge of a stall (preferably the upper edge and ease it down with no problem. I havent noticed any of the issues mentioned here so am a bit confused (true, that my normal state, but thats beside the point)...

The phyRelDensity of the forward fuselage is 0.5, which is pretty high (the FW190A3 uses a value of 0.15). That means the forward fuselage is given a larger chunk of the aircraft's total weight. Reducing that number will redistribute the weight (presumably farther aft).

Also, the engine nacelle has NO phyRelDensity property at all! I'm not sure what that does to the overall balance, but the engine was the heaviest part of that plane, I'd bet. You want the properties to be as correct as you can get em.

The cylindrical airfoil for the fuselage is in a rather odd place as well. Not sure where it should be exactly, but the fuselage of a streamlined jet aircraft DOES generate lift.

I don't have much time to tinker with the 162 right now, but simply by moving the inertia boxes and adjusting their density properties, using some of the other planes as a guide, you should be able to get it to fly right.

What you mentioned are all good ideas, but believe me when I say they won't work. The model HAS TO be moved forward in a 3D program. All of these changes will effect different things, but from a purely pivotal point of view, the airplane will be pivoting around a CG point (that's only based on where it was imported into the SM file) that will remain way off.
