Default c-g problem

Hi folks,

I am just putting the finishing touches to a model, it is a Modeltech VASP, 60" span pattern ship. The c-g is indicated to be 7 inches back from the LE, but I am too nose heavy, must be the heavy MVVS 49 lump up front.

By moving the battery pack half way down the tail and adding 4oz of ballast at the tailwhell I can get it to balance, but this brings the auw to about 7lbs. The destructions don't give any idea of what the auw should be, so a quick wing loading calc gives a figure of 27oz/sqft. This is the first time I have done this calc and I have not included the wing area that is coverd by the fus.

I have no idea what sort of wing loading figures I should be looking at, other than as low as possible.

Ideas or advice,

Cheers,

Chris
