I'll be coming at this build again later with a more specialized motor and power pack, likely the graupner Louie used on his build, and setting mine up in much the same fashion. In the mean time, I've come up with some dirt simple designs to try on my a pack. One is a regular wide delta with a slender delta shaped vane atop the vertical stabilizer. I don't know the terminology for this. It's like a t tail but with a delta on top rather than a t. The other idea is a half circle flying wing, basically half a nutball with a wider wingspan and elevons instead of elevator and rudder.
