I installed stab fences on mine last week as an experiment. I think they helped but not 100% sure. I usually put them on any plane. I think it's a placebo effect.
I'm having a blast flying it.
I have an Episode ready to fly soon too. It'll be fun to compare the 2 as I have never flown an Episode.
I always thought a DTFS wing would be unstable but I have to admit I don't feel any of that.
