1. The inner wing panels are going to be extended so the gear mounts in the fuse. It's a double edged sword a little bit, all the gear on the fuse is nicer for transport, but the added width also can make transport tougher. The inner panels will also need to be long enough to have the flaps be part of them rather than the wing panels.

2. The motor back where it is should provide a good balance without lead, with batteries in the nose. The fuel is right on the CG now which is preferred so there is no trim change during burn off.

3. Full flying stabs is just that much more complicated, particularly with the anhedral setup of the tail

4. Already had the stab moved up higher, it's a personal preference. The stab location looks good where it is IMO, it's how I originally designed the jet and how I would prefer it to stay. It also simplifies the mold as the stab will be a bolt on unit from the bottom of the fuse.
