The flight dynamics results are in – and it takes a lot of work to fly the Dropship! Unfortunately we have not been able to demonstrate controlled flight maneuvers yet. If I can’t understand how to fly it, it will be exceedingly difficult to explain to the AFCS.
Initially I thought this may be Dutch Roll. However, we are a lifting body and my experience with Dutch Roll has been limited to swept-back wings. But it does affect the vertical and longitudinal axes.

After searching online, I ran across “coupled roll-spiral mode” which is a condition I was not previously aware of. Anyone that can build a dampening routine for this mode is welcome to contribute! In fact, based on the article below, it is likely a combination of the two effects.
Time keeps marching on and I have gotten in a little over my head with this flight model and all the necessary changes that I hadn’t accounted for. As a result I removed all the availability on the booking calendar through April 10.
