Finally, my PC has pretty much gotten to the point where it doesn't like this project very much.
I suspect that there is too much stuff going on underneath what is actually visible for my PC to handle properly.
So, I present the 'completed'(?) version of the EH Project or as far as I can take it anyway.

This is supposed to be an ISD II, some details are wrong or out of proportion.
Without actually having proper plans to work with a lot of guesstimates had to be used.

Main weapons placements are correct according to the information I found on the interwebs.
They may not be correct, but I think they are close.
It flies, pretty well for what it is. I don't recommend trying to dogfight with it.
Do not remove the little wheel on the rear!

Flight controls as per a normal aircraft.
Trimmed to fly a little nose up hands off once it reaches proper flying speed.

Now has missiles fitted (Micro Interceptors) and associated decoy stuff, not that the decoys help much, the ship is that big.
AG1 to activate the 'emergency' engines.
Note that the emergency engines make the ship want to climb more than usual.

Suggested places to launch from;
Wright Airport
Wright Isles North
Yeager
Avalanche
Air launch

Inertia loves this ship. If you are headed down, it keeps wanting to go there even if it is in a nose up attitude.
It will pull out of a dive given enough height.

A system has been fitted to help it pull out of a dive.
It works automatically and is linked to the pitch controls, so it will also assist in bringing the nose up in normal climbs.

Rolling is the same as previously, once you get it started it is time to stop it.

Android users should download this with caution, it might work, but you could have problems.

Straight and Level flight for this is slightly nose up, due to the construction and placement of the cockpit. (I think I know where it is, but I'm not sure., it's been a while since I've thought about moving it.)

Upper hull detail is done in various shades of grey for the look of it.
Some small lights added in various places.
Main turrets modeled on shots from a YouTube clip I found.

If you want to use this a base for your own version, go right ahead. ;)

I'll add a link to a d/l that has all of my 'research' materials (pictures) soonish, for a relative amount of soon(tm)

As promised, a d/l link for the research I used to build this.

EDIT: just worked out this is roughly 1/8 scale (1/7.91 for those who want to be picky). The full size version is 1.6 km or an old fashioned Mile long.
