high wing, vtail
I 've watched quickies go around pylon 1, watching from under the pylon. My observation is that the v-tailed plane will scribe a nice arc , while a conventional tail will skid around the corner. When the model is "skidding" around the corner the angle of attack the wing takes will cause drag.
At least that my thought, then theres the argument that everyone else who wins is flying them. So take it for what it's worth. Good luck
