How dumb am I?
After posting my original post I weighed the lead needed to put at the nose again and realised that i miss read the scale. I only have to add about 175 grams or .7 lb. NOT 6 or 7 lbs in my original post. [X(]
I feel stupid im only 17 and lack the fundermentals of conversion.

Placing the battery under the tank is a great idea. And I will try it.
The tail does not sit on the ground after adding the nose weight so I dont think there is something wrong with the gear, however, I will check.

I am also having problems with the cowl. It does not fit right on the fuse (too small) but that is not as important as the cg so that can wait.

I will take the model to an experienced modeler at my club if all else fails.
It is a great looking plane and I can not wait to fly it.
I know where to come if I need anymore help.

Thanks for all your replies I will take or your opinions onboard.

You guys are legends your help is greatly appriciated.
