All are right on with the prop recommendations. How extensive was your dialing in on the thrust angle? As someone else mentioned, if your pulling left do to insufficient right thrust, then that is one more issue to fight when trying to hang. Check for up/down thrust as well. Is the model laterally balanced? Is the tail on 3D rates? The sim is a tool to learn, but by no means replicates hovering an actual model in real time. Practice will get you there. Good luck, Joe
