I mentioned previously that I have been experimenting with some different wing layouts to see which gave the most stable flight in the Sim. I had three different layouts, which all met the Aspect Ratio and external dimension targets. The centre section of wing was the part I could alter, and by altering the offset from the centre line of the aircraft, I could alter the length of the wing root. Making the wing root longer has the useful effect of bringing the centre of lift forward.

| Short Root | | | | |

| Medium Root | |

| Long Root |
I *think* i will be using the short root version. It may look like the obvious choice, but I first built the jet with the Medium/Long Root layout to try and minimise the amount of wing area which was buried in the fuselage.
Testing is looking promising at the moment. I have recently been trying to tune out some Dutch Roll that was occurring frequently by altering the vertical CG location. That was until i noticed the following in the Plots Manual;
Now its time to tune the artificial stability to get nice stable performance, and finalize the aero settings for accurate flight performance. Still plenty to do!
