You do not "need" anything for pattern beyond a model that is mostly neutral to airflow (symmetrical or semi-symmetrical wing chord and little of no dihedral). Dual ailerons help as you can work in differential for axial rolls. Not really necessary, but the smoother you perform the maneuvers the better your scores will be.

So . . . how much do you want to spend? Retracts? Kit or ARF?

If you're looking for an ARF for the Sportsman Pattern that will tale a .46 side the Kaos is a good model.


Or a Phoenix Models SeaBee



If you're going to get into the full-house tuned pipe pattern ships I'll defer to the wiser pattern pilots.
