Yes I did, my friend @tcinla. In fact, I stuffed quite a lot in there. Here she is, nicely leaning forward with the CG well in front of the MLG attaching points, rear moving surfaces placed in the back to counterweight. The final nose-up stance will move the CG tad aft, but, hopefully, it will be ok...
I wonder where the chaps building the old 1/48 Monogram Airacobra with everything "open" managed to stuff weight (ammo boxes, maybe?) 🧐
