Wing Attachment

A problem with my Storm is the wing attachment. Gradually the holes in the wing and the Aluminium spar seem to open with usuage. I now have 1-2 mm gap between the wings and fuselage/wing stub. I am ruminating on a CF tongue or fitting some sort of seal between wing and fuselage. Has anybody else had this problem and, if so, any bright ideas for solving it??

CG Position

The problem I have found in moving the CG back is that control in steering and premature lift off on take off become increasingly difficult. OK for those with a tar mac runway but grass can be a problem.

Directional Thrust

Has anybody found a directional thrust system that fits? On a Merlin 90, this model will virtually stand still! It crosses one's mind that carrier/harrier landings might be possible. Has anybody tried it?
