Large Shuttle Aerodynamic Issues

[JEF_300]

This save is technically modded, however none of these mods are being used/should affect the aerodynamics

I'm building a new shuttle, the Large Unmanned Cargo Kraft, or LUCK. Its gone well for the most part, for instance it looks fantastic, however there is a problem with the aerodynamics. I cant quite tell if its just (somehow) more stable in reverse, if its something to do with the Cargo Ramp up front, or if maybe the control surfaces are acting wired. I've been testing in Hack Grav for the "Glide Tests". It flys normally, until I turn a bit too far in any direction, at which point it flips so that the rear is facing forward. When i attempt to correct, it just ends up spinning.

Here's are some reference images: http://imgur.com/a/Bq1GK

Any and all help will be appreciated, so thanks in advance

Where are the Centers of Mass and Lift?

I'm guessing it's too heavy on the rear end, and the CoM is behind the CoL.

There's a link to images which display CoM and CoL
