I await flight tests!  If it turns out to be noseheavy, you could go to a forward swept canard to move its area ahead of the engine.  Also, area outside the booms might help, they need not be, and probably should not be, moveable.  In fact that could be one of the trim tactics to use, depending on how this model flies.

"Area outside the booms..."--don't quite follow; you mean perhaps flat-plate extending from the wing LE?  Or fixed flaps behind? or, extended stabilizer?  or...hm, can't think of any other alternative.

the forward-swept wing is a good thought if it turns out the CL needs to be forward.  Would look funky too.

Ah, I see...I'll keep that thought in mind on an "if-needed" basis.

Now sanding primer, preparatory to color. I'm a slow old man.

Hope it flies as well as it looks.  It is different.
